[Bug] Anne Pro 2 Bluetooth Not Working

[y-mx-b]

Describe the Bug

After flashing the QMK firmware, Bluetooth doesn't work at all. Using the Bluetooth keys to switch between connections doesn't work (though the LEDs will flash), and holding them down to get to pairing mode doesn't do anything either.

Additional Context

Everything works fine while the keyboard is wired with USB-C and the Anne Pro 2 Shine LED controller firmware works as well. It's just the Bluetooth functionality that isn't working.

Can confirm. No fix known as yet.

After the latest update from Obins it seems that the Bluetooth protocol was changed.

Pre-update everything worked fine, after updating the BT module and flashing QMK my Bluetooth stopped working.

[y-mx-b]

Would it be possible to flash an older Bluetooth firmware on the device then?

Would it be possible to flash an older Bluetooth firmware on the device then?

Yes. You can choose in obins archive version. I try couple latest's, and only version before 'Update to Bluetooth 5.0' work. After flashing from obins, flash shine and qmk.

#17483 might be what you're looking for. Sometimes I need to press the BT key twice before it actually connects. If you haven't tried out the fix, I'd recommend trying it out. My BT FW is 2.05

[tzarc]

Tried flashing BLE firmwares 2.03, 2.04, and 2.05 onto my C18, none want to cooperate.

[sehrgut]

Now that #17483 has been merged, does this bug still exist?

[tzarc]

Yes.

Tried flashing BLE firmwares 2.03, 2.04, and 2.05 onto my C18, none want to cooperate.

I also have 2.05 BLE firmware on a C18. I just flashed QMK and shine onto my keyboard and I thought the bluetooth wasn't working either, but then I tried pressing the bluetooth key twice (as suggested by @SgoSkz) and it worked. I'm on linux though so not sure if that makes any difference.

Just a heads-up, I was having issues trying to pair more than one device after flashing Obinskit latest version and then flashing qmk but it's apparently an issue with the obinskit version itself (I've tried to pair more than one device using only obinskit and couldn't make it either - only the first device paired after resetting bluetooth bindings worked). Then I flashed an older version of Obinskit (the latest of the 1.xx versions) and then QMK and shine again and it seems to working fine with this version.

Keep in mind that bluetooth connection is managed by the Obinskit firmare, even after flashing QMK - so the latest Obinskit version flashed will be version used for bluetooth. Also, keep in mind that even when using Obinskit directly it sometimes is troublesome to pair and you have to forget the device, reset the bindings and pair again - so it's probably a good idea to keep at least one key mapped to KC_AP2_BT_UNPAIR so you can reset the bindings for the current selected bluetooth slot.

[tzarc]

Had a stab at flashing a super old version of the BLE firmware, and this time QMK actually pairs and types correctly.

https://releases.obins.net/annepro2c18/firmware/1.14.1-alpha/ap2_c18_22_ble.bin worked for my C18 and current develop branch of QMK.

Some of them have the same filename but are actually different firmware, so even if you try ap2_c18_22_ble.bin from 1.14.1-alpha, it's actually different in 1.14.2-alpha. You may need to try more than one to find a working copy.
