Respeaker Core v.2 Bluetooth slave problem

Post by rodionov12 » Thu Feb 21, 2019 12:04 am

Hi!
I can't connect my smartphone and laptop to Respeaker Core V.2 in slave-mode (play music on board).
I'm using http://wiki.seeedstudio.com/ReSpeaker_C ... reparation guide to run bluetooth.

My kernel version:

Code: Select all

Linux v2 4.4.138-respeaker-r0 #2 SMP Wed Jul 25 11:29:18 CST 2018 armv7l GNU/Linux
There is no additional packages, clean "respeaker-debian-9-lxqt-flasher-20180801-4gb.img.xz" image (I checked sha256 sum, it's correct)

Code: Select all

respeaker@v2:~$ ps aux | grep bt | grep -v grep
root       573  3.3  1.2  28548 12208 ?        Ssl  15:52   0:17 /usr/bin/python3 /usr/bin/bt-auto-connect.py

 ps aux | grep blue | grep -v grep

systemctl | grep ReSpeaker
  brcm.service                                                                                  loaded activating start     start ReSpeaker Bt brcm service
  bt-auto-connect.service                                                                       loaded active     running         ReSpeaker bluetooth auto connect service
My laptop - MacBook Air 2015. I see device, can pair it, but after 5-10 seconds after connect it drops
My smartphone - Xioami A1. I can't see device, but I can see my phone from Respeaker using bluetoothctl.
