[bluetooth-dev] kernel mode on ARM+kernel2.4 : ppp problem
When trying to establish a ppp link I get the following problem :
> rf_conn 00:50:CD:11:10:AD 1 0
using channel 0
Couldn't attach to channel 0: Device not configured
ppp child died, now restart
What is a channel for ppp ? What Device is it complaining about, /dev/ttyBT0 ?
