I’m using a Q64 with the GR64 plug in. My unit connects to the GPRS, and listens on a socket for an incoming connection. After an hour, to the second (if no data has been received), the unit receives an unsolicited E2IPEV event as follows;
The ‘10’ means a socket error, but I can’t find what the error number 64548 means. The GR64 At Commands manual only lists error codes up to 255.
Shortly after this error code is received, the unit gets a NW DEACT error.
+CGEV: NW DEACT “IP”, “10.190.12.40”, 1
I’m assuming that this is as a result of the E2IPEV error, rather than the cause of it.
Could the Vodafone network be automatically closing the socket and/or disconnecting the unit from GPRS if it has been idle for this time?
