Just something I noticed that I thought would be worth people knowing… If you disconnect the remote bluetooth device, and there’s still an active “send” going on, the send won’t fail; what happens is that your sent character pops up on your recieved data stream. It’s as though the device goes into TX/RX cross-over mode. Even wrapping my code in checks to confirm that BT is connected, I still get one character popping back when i close the connection to, in my case, the PC. I expect this to be less of an issue for my use when my code is final and operating normally, but while I am developing both the netmf code and the PC code, this happens pretty much every time I quit my PC app and if I was using PC–>netmf control I may get into trouble; again, just something to be wary of.
