hello,
with your help i had quite a success in sending data from my mobile phone to
bluez.
but there's something i don't understand.
i registered a SP service: sdptool add --channel=10 SP
./rctest -d
rctest[2482]: Waiting for connection on channel 10 ...
rctest[2483]: Connect from 00:00:00:00:00:00
rctest[2483]: Receiving ...
rctest[2483]: Recevied 51 bytes
rctest[2483]: Disconnect
and the programm doesn't exit, i have to use ctr-c to stop it. is this
normal or is something going wrong although the receiving was successful?
and something else:
if i try to receive with the 'r' option there's an error:
./rctest -r
rctest[2458]: Waiting for connection on channel 10 ...
rctest[2459]: Connect from 00:00:00:00:00:00
rctest[2459]: Receiving ...
rctest[2459]: Read failed. Connection reset by peer(104)
rctest[2459]: Disconnect
has anybody an idea what's my fault?
i think somehow it's possible to use the read socket function but not the
recv function...
regards,
franz

this is normal, because you can connect another time.

You received data (one UIH frame) and then the phone disconnects you.
Actually they are the same 51 bytes as above, but you only see an extra
error message.
