DESPERATE HELP NEEDED! HC-06 Bluetooth

Just ordered that. Will try it at the weekend as I’m working away this week. Fingers crossed.

On the subject, is this just a case of plugging it in and it’ll override the onboard Bluetooth of the 3B+, or will I need to run some commands?

@Dinsdale Although I don't think this would be any help, you can disable the onboard BT by modifying the /boot/config.txt file and adding dtoverlay=pi3-disable-bt on a line.

@mitu Perfect, I’ll try it anyway. Thanks!

So I disabled onboard Bluetooth, rebooted, and connected the new dongle. It flashes - but no change.

Now this is most likely be because this dongle won’t be Plug n Play. How do I install it? There’s no instructions in the package for Linux.

@Dinsdale I might have a fix for you! It would probably be best to restore things back to default with all the changes you have probably made. This fix should allow you to sync to the built-in bluetooth. (I recently found this fix while trying to help a friend snyc a bluetooth xbox one controller. The things we do for friends and family!)

Create a new file using nano...

 sudo nano /etc/modprobe.d/bluetooth.conf

Add a single line to the new file...

options bluetooth disable_ertm=Y

Exit nano, saving the file in the process

This fixed my connection issues with the xbox one bluetooth controller

Thanks man! Unfortunately it didn’t work.

There isn't, at least not for the PI. Some work with the PI but some don't. They auto-install or are auto -detected

Yeah, I think this one is Plug and Play. I see it in lsusb and it works when I search for Bluetooth devices, though to be honest, this could still be the onboard bluetooth that I haven't successfully disabled - because when I take the bluetooth dongle out, and search for new Bluetooth devices, it just hangs on "searching" and doesn't give me an error. Does this mean the Bluetooth is disabled?

Anyway, here's the error in full when I connect via onboard or the dongle. I have typed this out manually. Hope it gives someone a clue.

I’ve been trying tonight to make some progress. I Google’d the above error and found a reply from @RadBrad87 in this thread: https://retropie.org.uk/forum/topic/1905/retropie-3-8-bluetooth-configure-issue/40

Exact same error... so I tried optimistically to remove the PS3 driver (I didn’t have it installed in the first place) and all associated packages... but still nothing.

I also noticed separately that I could enable the serial interface - and when I’ve Google’d the HC-06 a lot of references where made to this and SPP... but no dice. Same issue.

What the hell is it?!

Dinsdale

Does anyone know why it connects with RFCOMM and why it isn’t recognised as a controller?

Dinsdale

This is now resolved. The guy who did this further did some investigation and found that he needed to convert this to HID to work on Raspberry Pi and other platforms OOTB. He did this using an RN-42 I believe. Finally... works a charm!

So, on the off chance anyone has the same bizarre situation as me, this is what did it!

@Dinsdale What is RN-42 ?

Dinsdale

@ByteThis Diffferent type of Bluetooth module, I believe. Could be wrong...
