I have opened a rfcomm channel synchronously: [selectedDevice openRFCOMMChannelSync:&mRFCOMMChannel withChannelID:10 delegate:self]; [mRFCOMMChannel retain]; I have a problem: I've tried to enter the at commands using writeSync, but there's no response. I have no idea how to read the incoming data from the mobile phone. How to write the at commands and read the incoming data? Note that on many phones you will need to send the command string terminated by a \r, rather than the more usual \n. This caught me out on my SonyEricsson T630 for a while.
