Default Bluetooth Troubleshooting Guide (READ ME FIRST)

The Bluetooth Troubleshooting Guide
Many people are new to Bluetooth, and they may not know entirely how it works. I think maybe a little troubleshooting guide is in order. Most of the problems people experience with Bluetooth have some pretty simple solutions. If you follow through with these tips and are still having trouble, then post your problems according to the directions below.

First off, What is Bluetooth?

Bluetooth is a wireless protocol for transferring data and remote commands between Bluetooth enabled devices. The advantage of Bluetooth is that it's simply a protocol for developing Personal Area Networks (PANs) and the actual implementations of different functions is essentially limitless. Different fuctions have different profiles which perform different tasks. To use wireless headphones, you use a different profile than if you were going to transfer picture files between two devices. Basically, Bluetooth can do anything as long as there is a profile for it. If you're really interested in what exactly Bluetooth is visit http://en.wikipedia.org/wiki/Bluetooth

Bluetooth works on the concept of Pairing. That is, one device will send a prompt for another device to share a secret key that the user inputs. The two devices, by sharing a cryptographic secret key will now exchange their list of profiles (supported services) with each other. Devices that have the same profiles can perform the actions associated with that profile. Some devices have no way to input a key (For example, Wireless headsets that have no keypads), so their pair key is built in. In the case of the wireless headset, the user of the devices begins the pairing process from the device with the input console (For example, the cell phone) and enters the sharekey that is hardwired into the headset. In this case, the pairing procedure can only be one way due to nature of the devices. For more information see http://en.wikipedia.org/wiki/Bluetooth#pairing

What does my Samsung PMP support?

The Samsung line of Bluetooth enabled PMPs (YP-P2, YP-T10, YP-S5, etc...) all share a common feature set. That is, they support specific profiles, and have somewhat esoteric procedures for pairing with other devices. All of the Samsung devices support the Advanced Audio Distribution Profile (A2DP) which is used for pairing with wireless headphones for listening to music. This is different from the Headset (HSP) profile which most cellular phones have to pair with the little bluetooth headsets for calling without the phone physically head to one's head. HSP only supports low bitrate mono sound transfer and is not capable of stereo music support. Hence the Samsung players do not support it. The players also support the Audio/Visual Remote Control Profile (AVRCP) so you can control the play/pause and change songs (etc) directly from your remote device. This is not required to use bluetooth headphones, but the Samsung Players support the function.

With the Samsung Bluewave firmware update released for the YP-P2 and the YP-T10, the player also supports the Object Push Profile (OPP) which allows a sender to "push" files to a paired device (images, music, contact cards, etc). The Bluewave also introduced the Hands-Free Profile (HFP) which allows the players to act as a hands-free calling system for the phone, enabling basic control of the phone such as making a calls from the PMP. Again HFP is not HSP because it allows for two way control. The HFP device can control the phone and make calls whereas an HSP device simply plays the broadcast audio signal from a call. The Samsung Bluewave players support the HFP Hands-Free Profile.

What functions does my mobile device support?

Don't be confused between OPP, A2DP, AVRCP, HSP and HFP. The easiest way to find out what your device supports is to look it up. If you don't have the original documentation that came with your device you can often find out specifically what it supports through a little research.

Cell Phones
If you have a cell phone and you're not sure what profiles it supports, the easiest way to find out is a website call PhoneScoop. Simply go to http://www.phonescoop.com and use the JUMP to a phone feature. Enter your phones colloquial name (For Example: The Moto PEBL) or by the model number/name (For Example: Samsung SGH-U600). The PhoneScoop search will find your phone and display it's page. What you're looking for is under the connectivity tab in the Bluetooth section. It will show you a list of supported profiles. You want to make sure that it supports the profile you intend to use with your Samsung player. If you don't see it in the list, you can't do that thing with your phone. Of primary importance is the fact that to pair your phone with the Samsung player (Bluewave) your phone has to support the HFP. If it doesn't support HFP, then you won't be able to use the Samsung player to make calls. If it doesn't support OPP, then you won't be able to pair with your Samsung player to transfer files.

Also, some wireless carriers in the US and Canada put special firmwares on their handsets that have feature sets that are significantly different from the stock manufacturer firmware. It's very unlikely that you will get a Bluetooth profile that the phone didn't support before, but it is somewhat likely that a manufacturer might disable a profile that the phone otherwise supported. For example, Verizon Wireless is notorious for disabling any Object Exchange profiles (Including OPP) or at the very least crippling them so they only support contact card files. If you suspect this might be the case, you might have to do some research with your specific carrier to ensure that you will have the capability to use the profile you want.

Wireless headsets/Earphones
If you're talking about a wireless headset of the ubiquitous, hangs from one ear variety:

Then, in all likelihood, it only supports the HSP profile and it is not compatible with your Samsung Player.

If, however you have a different wireless headset, like headphones, then you have to find out what profiles they specifically support. It's a safe bet that most wireless headsets support the A2DP profile for listening to audio from your player. If you're unsure though, then you can go to a site like http://www.amazon.com and search for your specific device. Somewhere down in the list of features, you will find what profiles it supports. If it doesn't have the A2DP profile then you can't pair it with your Samsung player for listening to audio.
If you want the ability to play/pause and control the song from the headphones, you will need to buy a set that supports the AVRCP profile. Most listings don't advertise this fact, but if they say they can control the song directly from the remote device, it's likely that they do support AVRCP.
Help! I can't get my Samsung player to work with my Bluetooth Enabled Device!

Don't fret. Often times the solution to your problem is a simple one. Before posting a terrified sounding query on the forums, make sure you try all of these steps listed. If you're still having trouble, then post and maybe someone here has a solution for you.

  • First, you're going to want to make sure that you have the newest firmware for your device. By the time that most devices are manufactured, shipped to your local warehouse, and finally put on store shelves, they're months old. That means that it's possible (nah, probable) that you have an out of date firmware on your device.

    To see what firmware version you have on your device, go to the Settings -> System -> About section and find out your firmware version. Then go to the Samsung Download Center and find the firmware section for your device. If the firmware listed is a higher version than the one on your device, download the new firmware and follow the instructions to update your player.

  • If you have the newest firmware, then we can start worrying about Bluetooth issues. Go into the Bluetooth setting section on your player. The device will ask if you want to turn on Bluetooth. Select Yes and continue. You're going to want to make sure that you set your device as discoverable. Go to Bluetooth Settings -> Discover Option and ensure that Discoverable is selected.

  • Now, you're going to want to make sure that you do the same Discover option on your phone. There are too many different ways to do this for this guide, but the essential pattern is the same. You need to go to your Bluetooth settings menu and find the Discoverable option. You're going to have to make your phone discoverable for the initial pairing to be successful.

    Once you've paired your devices successfully, you can turn Discoverable off if you so desire, the devices will still pair if they already know where to look. Discoverable is only required on the initial pairing of any device.
Ok, if you've followed these steps to facilitate pairing and you still can't solve your problem, maybe you're doing something wrong. Here are some pointers to make sure you get things working. Note, these are the procedures that work on the Samsung YP-P2 (because that's what I have)

  • A2DP Headphone Pairing- If you've got a set of Bluetooth headphones that you want to pair with your player, then you're going to have to make sure that they're on and charged. If you've followed the initial directions above, you can go to the Bluetooth menu and select Stereo Headset. If you have never paired headphones with your device before, it will automatically go about trying to detect some A2DP compatible headphones; don't worry all headphones are automatically discoverable, don't worry about making them discoverable. If the device doesn't automatically start searching, you can select the search function (on the P2, just tap the magnifying glass).

    Once the Samsung player finds your device by it's name, select it and it will prompt you to enter a passkey. This is the part where you have to have the operating instructions for your specific headphone set. Most devices without programmable passkeys just use the passkey "0000" so if you don't know what yours is, you can try that. If that doesn't work, you will have to find the owners manual for your headphones and find their specific pass code. If you enter the correct passcode, give the Samsung player a few seconds to pair and you should have successfully paired with your headphones.

    If your headphones support the AVRCP profile, then they will have controls on them to control song functions directly. If these controls exist, then there is no extra step to pair or make this function work. When pairing for A2DP, this will automatically be enabled on compatible devices.

  • Pairing with your OPP enabled device for File Transfer- The key to understanding how this works is to understand that the file transfer is a one way process. The device that you want to send the file from has to initiate the process.

    If you want to send a file from your Samsung player to your cellphone (assuming your cellphone supports OPP and can play back whatever file type you're sending) Then you will go to the Bluetooth menu and select File Transfer. Your player will search for a discoverable device. If it finds one, select it and it will prompt for a passkey. Make any passkey you want and press "Ok". The receiving device should flash you with a prompt to accept the file. You will enter the EXACT SAME passkey as you made on the Samsung player and the file transfer will take place. Be warned though, that the Samsung Player cannot pair for file transfer simultaneous as it is paired for any other function. If you are paired to a set of headphones, or you are paired to your phone for Hands-free it will prompt you to disconnect before you can connect for file transfer. You must select "Yes" to be able to pair for file transfer mode.

    If you want to send a file from your phone to the Samsung player, you do not want to be in File Transfer mode on your Samsung player. You will want Bluetooth to be on, and your device to be discoverable, but do not go to the file transfer screen on your Samsung player. Begin by initiating the file send from your phone (Using whatever steps your phone requires) and find the Samsung player. Select it and the Samsung player will prompt you to accept the file. Select "Yes" and the file transfer will begin. You don't have to disconnect other pairings if you initiate the file transfer from your phone, by the way.

  • Pairing with an HFP enabled phone- The current firmware has trouble pairing with a phone from the Samsung player side. The easiest way to pair with your phone is to initiate the process from your phone. From your phone, search for devices from the Bluetooth menu. If you have made the Samsung player discoverable, then it will show up in found devices on your phone. Select it and you will likely be prompted for a passkey. Enter any key you like, but remember it. You will then be prompted to enter the EXACT SAME key on the Samsung player. If you do so, then the two devices will pair and the Samsung player will now act as a Hands-free device to your phone.

    Keep in mind that you can search for the phone from the Bluetooth -> Mobile Phone menu. The process is similar from this direction, find the phone (make sure it's discoverable) and enter the passkey on both devices. The phone should then connect to your device via the HFP.

    Also, you may way to go into your phones settings and make the Samsung player a "Trusted Device" which will allow you to connect and pair without entering passkeys in the future. If you don't do this, it's likely that you will be asked to connect each time the Samsung player tries to pair with your phone (By default the Samsung players automatically trust any device they've been paired with previously).
"I've tried everything and I'm still having issues"

If you still can't solve your Bluetooth issues at this point and you've verified that:
  • Your device supports the profile you want to use
  • Your phone carrier hasn't disable the profile you're trying to use
  • You have the latest firmware on the Samsung player and your specific player supports the profile you want to use
  • Both devices are discoverable
  • You've followed the directions for specifically pairing your devices
You may have a legitimate issue that this guide doesn't cover. When posting on this forum, please try to give your fellow members some help by listing some specifics about your situation. Please try to include:
  • Your specific Samsung player
  • The firmware version you're currently using (Settings -> System -> About)
  • The device you're trying to pair with, including the specific model number.
  • If it's a cellular phone, also give the wireless carrier.
  • What you've done yourself to resolve the issue, including whether you've tried all the above troubleshooting tips.
Thanks. Hopefully someone will have an answer for you. Keep in mind that the Bluetooth technology is a little fickle and can work brilliantly sometimes, and not at all other times. If it's worked once for you and suddenly stops working for no apparent reason, just keep trying. It will work again, it's just a matter of time

Sassafras.

Your tutorial mentions nothing about the AVRCP profile. The T9B,T10,P2,& S5 also support this profile which allows a set of speakers or headphones with pause/play, FF, and Rewind to control the player.

To my knowledge it does not support the AVRCP profile. This is, of course, an anecdotal observation on my part because I have paired it with two separate devices that support AVRCP (A car stereo and a home stereo) that both pair using the AVRCP profile with my Samsung phone. When paired with my P2, it only connects using A2DP control. After researching through the Samsung literature, I cannot find any method or mention of a working AVRCP profile. Please provide a link as to where you know this, and I'll research it and add it.

Whether Samsung mentions it or not, the P2 does support AVRCP (Remote Control Profile)... as proven by my Motorola S9 headset.. ff/rev play/pause are all available from the headset itself when used in Bluetooth mode with the P2.

It's possible the protocol is being used partially or not recognized due to the implementation on your car/home stereos. Bluetooth can be a tricky little devil sometimes, as you well know..

Nice Guide btw...

Interesting. I should research it more thoroughly. I didn't find anything in the literature, and since I'd never gotten it to work myself, I simply assumed it didn't exist. It's definitely a nice feature to have.

Great post, Sassafras!

I have a question ... in one of the posts on the abi forums (I think) was a posting for a piece of software called: OBEX COMMANDER (v. 1.9.2) that allows files to be transferred between devices. My question is: if I have the OBEX application on my computer can I use it to transfer files (music, pics, text, etc.) from my P2 to my PC and/or from my PC to my P2???

To me, that would be the ultimate in convenience and capability!

p.s. Your topic thread should be "stickied"

If you do a word search in the P2 pdf manual, the terms 'A2DP' or 'AVRCP' never appear. Although the manual doesn't explicitly mention the P2 support A2DP, it does. The same goes for AVRCP. So, right now I can not provide a reference which states A2DP or AVRCP is supported. I just use them.

I do have speaker and headphones that explicitly state in thier manuals they support AVRCP and they control these players.

It is. I can sticky my own shiznit.

Anyway, If your Bluetooth control stack on your PC supports the OBEX profile, then you can pair with the P2 and send files. But as the guide says, the P2 uses Object Push (a specific implementation of OBEX) so you have to initiate a file transfer from the sending device.

Obviously, because if I had found reference to AVRCP I would have added it. I guess I'll just add it to the guide when I get around to it.

Edit: Fixed the guide. Thanks for the suggestion!

Yah, i found it can be controlled from other devices too....
I was playing on the pioneer bluetooth in-dash decks and i could control my p2 by just pressing the next button the dash unit. So it even works with car decks, well, atleast the $300 one i used.

(i wish the dNse would work while using bluetooth, wonder why that is?)

Thanks for this guide! I was trying to enter the address for the p2 as my passcode all night, I read the guide this morning and realized that I just needed to enter my OWN passcode in both my phone and the p2. Now everything works fine.

Read your guide and knew most of it already. Didn't know about phonescoop though. I think I will be using that site before I purchase my next phone for sure. Anyway's, I know my samsung phone does support opp with the v-chip, but I can't remember if my phone has it or not and can't find the paperwork that came with it. Is there a way to find out through the phone itself? No big deal, probably going to get a new phone soon, from samsung of course so i'll just make sure the v-chip is already in it.

What do you mean by v-chip? The only v-chip I know of exists in television sets to control what your kids watch...

That said, if you go to phonescoop on your specific phone, it will have a section about Bluetooth Supported Profiles: It will say "OPP" if it supports file transfer. Be warned though, that most Verizon phones are "OPP (V-Card only)" and that means you can only transfer contacts, but no pictures or music.

Sorry! I meant v-card. Mine isn't verizon, live in canaduh! pretty sure I'm restricted to just contact/calender info, no pic.,or mp3 files. Like I said i'm probably going to get a newer phone soon anyways and i'll be sure to make sure it has full bluetooth capabilities.

Keep working on it, I'm sure you will make it work. The YP-P2 is a great hobby to re-connect bluetooth devices because you have the opportunity to reconnect again and again.

Hello all!

I am sorry to awaken a dead thread but I would greatly appreciate some help. I recently acquired a P2 16G and have been trying, unsuccessfully, to use it with my mobile phone. I have read the guide at the top of this thread but it doesn't seem to cover my sittuation.

- I have upgraded the P2 firmware to the latest version (5.10)
- The phone is a Samsung M300
- The phone supports both HFP and OPP as per the info on the website provided above.

I am able to get the phone to pair with the P2 as I have entered the P2 in the "trusted devices" list on the phone which required me to enter my pass code on the P2 when the phone connected to it.

The phone also appears in the P2's list of bluetooth devices when I go into the "delete device" category of the of the bluetooth settings menu.

The problem is that when I go into the "mobile phone" section of the bluetooth menu the P2 flat out refuses to search for the phone. The search button that should be at the bottom right of the screen isn't even there. I am able to search for stereo headsets and file transfer devices but it just won't search for phones.

Does anyone have any idea what the problem could be? Its bluetooth capabilities was one of the selling points of the P2 for me and as of yet I havn't even been able to try it out.
