I’m a happy owner of a Hyperpixel.
It works well with my raspverry but when I tried to pair a BT keyboard, I discovered that nothing seems to work.
The command hciconfig has empty content.
$ hcitool scan Device is not available: No such device $ systemctl status hciuart.service ● hciuart.service - Configure Bluetooth Modems connected by UART Loaded: loaded (/lib/systemd/system/hciuart.service; enabled) Active: failed (Result: exit-code) since Sat 2017-12-23 21:12:00 UTC; 1s ago Process: 432 ExecStart=/usr/bin/btuart (code=exited, status=1/FAILURE)
I don’t know where to search…
