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 > > > Have seen what happening over the air, when this happens...
