Okay, here's what I did so far:
- Enabled built-in BT on pCP's Wifi Settings page, rebooted.
- Installed bluetooth-4.14.81-rt47-pcpAudioCore and pcp-bluez from pCP'
repository.
- Installed evtest from the official piCore repository.
- ssh'd in and started dbus and bluetoothd:
Code:
--------------------
sudo /usr/local/etc/init.d/dbus start
sudo /usr/local/lib/bluetooth/bluetoothd -nd
--------------------
- Loaded uart_hci kernel module and ran hciattach:
Code:
--------------------
sudo modprobe hci_uart
hciattach /dev/ttyAMA0 bcm43xx 921600 noflow
--------------------
- Started bluetoothctl and paired the device:
Code:
--------------------
tc@piCorePlayer:~$ bluetoothctl

--------------------
The device is now available as /dev/input/event0 and I can see its key
presses with evtest.
So far so good, but when I reboot I have to start the whole procedure
from scratch again. So, for me, persistence is the first problem to
solve. I would consider automatic reconnection a part of that.
What I tried so far was to add "/usr/local/etc/init.d/dbus start" and
"/usr/local/lib/bluetooth/bluetoothd" to /opt/bootlocal.sh (before the
pCP start command as I assume that blocks while pCP is running), but
that led to the Pi no longer being able to boot. I'm out of ideas for
now and would be very grateful for a nudge in the right direction.
