I use the imx8mmini board (Linux version 4.14.98)
When i test bluetooth, use the following command:
# bluetoothctl
[bluetooth]# power on
[bluetooth]# pairable on
[bluetooth]# discoverable on
[bluetooth]# scan on
[bluetooth]# pair 22:22:C6:AB:48:DB
[bluetooth]# trust 22:22:C6:AB:48:DB
[bluetooth]# quit
# export $(dbus-launch)
# /usr/libexec/bluetooth/obexd -r /home/root -a -d & obexctl
[obex]# connect 22:22:C6:AB:48:DB
[22:22:C6:AB:48:DB]# send /home/root/123.png
Now, picture can be transferred to the tablet via bluetooth.
But when I transfer files to the board through the tablet, it can't.
Why is it identified as a Bluetooth headset device？？？
