Hi,
i have problem connecting bluez (currently im using 5.49 from
debian:unstable and linux-4.14) to my CSR8811 (connected via 2 wire UART).
hciattach works and i can use some bccmd commands but when i do a
warmreset (to activate my pskey changes) bluez seems unable to get a valid
reply from the chip :-(
here my commands:
root@BLOKS ~# hciattach -s 38400 /dev/ttyS1 bcsp 38400 noflow
Device setup complete
root@BLOKS ~# hciconfig
hci0: Type: Primary Bus: UART

while executing the commands above i get the following kernel messages:
[ 308.225409] NET: Registered protocol family 31

any ideas?
Thanks,
Tobi
