Respeaker Core v.2 Bluetooth slave problem

Hi!

I can’t connect my smartphone and laptop to Respeaker Core V.2 in slave-mode (play music on board).

I’m using <LINK_TEXT text=“http://wiki.seeedstudio.com/ReSpeaker_C … reparation”>http://wiki.seeedstudio.com/ReSpeaker_Core_v2.0/#preparation</LINK_TEXT> guide to run bluetooth.



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

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.
