Tool/software: Linux
I'm trying to use CC256XCQFN-EM connect to BBB, but I can't get it work
I attached CC256XCQFN-EM to BBB UART4
0.947623] 481a8000.serial: ttyS4 at MMIO 0x481a8000 (irq = 32, base_baud = 3000000) is a 8250
above message is shown on dmesg, so I think UART4 is initialized
then connect to board by
RF1 1 GND 3 CTS 7 Rx 9 Tx
BBB p9_2 p8_33 p9_13 p9_11
RF2 7 3.3V 19 nshutd 18 RTS
BBB p9_4 p9_15 p8_35
after startup pull BBB p9_15 to high
call
dbus-daemon --system
/libexec/bluetooth/bluetoothd &
finally
hciattach -n -s 115200 /dev/ttyS4 texas
do init uart
do u init
texas_init
Initialization timed out.
I also tried
hciattach -n -s 115200 /dev/ttyS4 any
do init uart
do u init

Thanks for any insight
