Connecting to a TCP end-point with AT#SD=1,0,80,"",255,1,1 works fine and returns OK, but connecting in online mode with AT#SD=1,0,80,"",255,1,0 hangs up the interface completely (no CONNECT received, no error messages).
I’m using EVK2 with HE910 interface board and I’m connected via the USB B connector with a terminal. The board is powered by a DC power supply. I’m on the last firmware revision of the modem (12.00.006).
Am I doing something wrong?
Problem was with the terminal – turning RTS/CTS mode helped.
Yep this is the usual catch. Alternatively you can use no flow control with AT&K0.
