Hi
I’m using a M1306B which is running WIP Soft v201 on Open AT OS v312.
I am having a problem with open TCP sockets. Everything is fine the first time I attempt to open a client socket to my server after power on. I can open the bearer, start the bearer, create a socket connection with the AT+WIPCREATE command (and get the +WIPREADY: response) and then I can issue a AT+WIPDATA=2,1,1 command and get the CONNECT response. I can send data to the server and so on. I then close the session by issuing a +++ and followed by AT+WIPCLOSE.
Everthing seems fine so far but now if I try to make a second connection I don’t get the CONNECT response to the AT+WIPDATA=2,1,1 command (in fact I get no response at all and the UART stays in the modem mode). I have tried closing and stopping the bearer but and repeating the entire process but it still won’t connect. It will only connect the first attempt after power up.
Is this a software problem or am I missing a vital step after closing the connection? Any help would be greatly appreciated.
PS.
What is the latest firmware version and IP stack version and where can I downoad it from?
