I have the following scenario: I’m opening a UDP socket in Continuous Mode (where [ETX] is considered end of data). If i read and understand the AT command manual correctly, the modem in this mode should send the current datagram (with ETX marking boundaries) and change from DATA mode to AT mode when parsing the [ETX]-character? Now I’m only able to send the datagram when sending “+++” sequence, which is a pretty slow solution (1 sec guard time before and after +++).
I’m opening the socket and DATA mode with “AT+WIPDATA=1,1,1”
ETX = 0x03?
What am I doing wrong?
EDIT: I was mistaken, the modem did actually send the datagram when parsing the [ETX]-character, but it still wont exit to AT mode without +++.
