hi Venu,
1 . When we issue command
#hciattach ttyS1 bcsp 115200
we are able to see the tx line toggling from the processor .
2. But when we issue command
#hciattach ttyS1 any
hci0 device is created.
But no toggling in tx line when we issue command "hciconfig hci0 up"
we dont have any debug interface.
-Regards,
Shankar
