@dos Weird. I had to downgrade the Redpine driver to 1.2.2 according to this post 70 in this thread forums.puri.sm/t/bluetooth-sup…

However, dmesg says "redline_91: rsi_sdio_ack_intr: unable to send ack"
and
"hci0: Bad flag given (0x1) vs supported (0x0)"
It won't connect after I input the PIN in the keyboard.
