Librem 5 BT: change operating mode

Hardware Librem 5
1

Hi! I noticed recently that the bluetooth of my Librem 5 does not find bluetooth 5 devices anymore (my mi band 4 for example).

dmesg reports:

redpine_91x: FW Version  : 1.2.20.0
redpine_91x: RSI FW Version      :  0000.2.1.0.0502
redpine_91x: Driver Version      : RS9116.NB0.NL.GNU.LNX.OSD.2.0.0.0024
redpine_91x: Operating mode      : 5 [Wi-Fi STA + BT EDR]

I saw elsewhere on the forum and here or here that the Operating mode should be 13 (Wi-Fi STA + BT DUAL). Anybody knows why mine shows 5 and how to set a different mode?
I could not find this info anywhere.

(I’m on Byzantium)

Thanks!

Mine shows the same

Thanks, according to this (table at page 9), Mode 5 does not use BT LE. Do you have a BT LE device you can test your L5 with (to see if it appears in the device scan)?

Thanks

Bluetooth not found but service runs no default controller

Thanks, this worked (it switched the operating mode to 13), but then I had the same problem of the OP in the other thread. Bluetooth just did not work (it was seen by rfkill, but nothing more). I had to revert back to mode 5 now.

Ah I see now that
“Firmware vesion 2.0.0024 broke BLE so we need to disable dual bluetooth support”
I asked on the gitlab issue whether it will ever be supported again
