410c - bluetooth not working in 17.09 release

Products Support DragonBoard410c
#1

hi,

bluetooth is not working in 17.09 release, it is able to scan the devices, but it does not pairs, nor able to transfer the files using bluetoothctl/obexctl/bluedevil-wizard.

regards,
vinaysimha

Could you please try with latest release:
https://releases.linaro.org/96boards/dragonboard410c/linaro/debian/latest/

With and without WiFi.
Also sharing the HCI dump of pairing step could help (btmon).

#3

with this new release https://releases.linaro.org/96boards/dragonboard410c/linaro/debian/latest/

wifi and bt both are not available

hi vinay,

A few questions for you:

  • are you using a DB410c?
  • which image have you flashed, and how (which method)?

Can you please send a full log of the serial console , including all traces from power on?

thanks

ndec,

bluetooth is working fine , able to pair and send files in 18.01 release, i had flashed the wrong appsboot boot binary.

fyi,

In arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi , led-trigger-bt should be hci0-power instead on only “bt”.

label = “apq8016-sbc:blue:bt”;
linux,default-trigger = “hci0-power”;
