Bluetooth pairing process is different, 6.0 vs. 6.1

[rock99rock]

The device is Holux GPSlim 236. The phone is Hermes. The phone will pair without question on a 6.0 rom, does not matter who cooked it.

It will specifically not pair with 6.1 roms.

I can see the device when scanning for bluetooth devices, i can choose it, it asks me for passcode, but will not accept the "0000" as the passcode. (tried hardware and software keyboards). IF i type in a passcode OTHER than "0000", it appears to pair, i can see the spp slave service and select it, but once the gps software tries to talk with it, it asks to pair again.

Something is definitely different in the pairing process between 6.0 and 6.1.

Any suggestions are greatly appreciated.

Also see thread about it here from the Himelaya:

Did you select it as a serial port? You have to do this after you pair the device with the phone!

I am not familar with gps units, does it have a pairing mode like a headset? I know with my Plantronics headset, if I let my phone discover it without the headset being in pairing mode, the phone says it pairs with it, but it really doesn't, so I put it in pair mode then turn on bluetooth on my phone and pair up as normal(0000 passkey) and all works fine.

I have exactly the same GPS unit and have no problem pairing it with the probably 15+ WM6.1 roms I have tried.

Try leaving the battery out of the 236 slim for a few minutes and see if that helps. (can't remember is there is another way to reset it)

In the latest PC Pro magazine in the UK, there is an article on WM 6.1. It says:

"There's another neat feature in WM 6.1, namely that when you try to pair the phone with something like a GPS dongle or hands-free kit that has a fixed PIN, the operating system will cycle through a set of common codes (0000, 1234, 8888 and so on) to try to find the right one."

It goes on to say that there is the potential to get locked out of the pairing if it goes wrong.

I have to say that I have not had any problems pairing with my GPS unit and my car kit, using a number of 6.1 ROMs. Indeed I have seen no evidence of the above software routine trying to pair for me. Possibly, that routine will only appear in the production ROMs, rather than the development ones which we use on XDA Developers.

I had issues with the same device on some roms. I eventually changed BT drivers from WM6 and all went back to normal.
On some WM6.1 roms things went OK though.

Try not using any password when you try and pair it manually.
If it asks would you like to pair your device automatically select no and do it manually.

I was having this problem but WM6.1 does not require a bluetooth passcode for most devices.

You are not the only one :D

I reverted back to the 6.0 and it pairs without issue. I am thinking that alot of these cookers do not pay much attention to the development of bluetooth in some of their roms. Its not like I changed something on the GPS, so something must have happened with the software.... Still investigating. I hope it works on schaps new rom.

this method paired my jabra automatically, it didnt even ask if i wanted to do it auto, i juck clicked "pair" and there it was.



When pairing the holux 236 on the other hand, it would ask for a passcode, then reject it if you put in the correct code of "0000". If you canceled it, it would appear in the connected devices list!!, but still ask to pair once the gps application tries to connect. VERY jacked up.

Did that article describe any way of disabling that feature? That functionality could easily trick a simple bluetooth device if it is not expecting such a rampage of codes...

No, there was no mention of if it could be disabled.

Wam, which rom are you using now that it works with? id like to download and try it. The 5 or so ive tried did not work.

I power cycle the device without any change in pairing succession.

Thanks!
