Dear all
I have a strange problem with using hciattach to a uart bluetooth
device . I use a script to attach the device , but i need to attach two
times to get the build ID.
hciconfig -a :

I have no idea what that is so, but I am not the expert in the UART
area. Maybe you have to change or add a sleep time to the CSR init
routine or switch the module to BCSP.
