sim340 project
Hi,
I've got a device with sim340 to communicate via GPRS network. I had a problem with the way the communications works in this device. From every 5 seconds my device controller execute those at commands:
at+cipshut
at+cipstart="TCP", "<my wan IP>", "<my wan Port>"
at+cipsend="<my info>", n bytess to send
I don't know if i can use the at+cipsend without repeat from each 5 seconds the at+cipshut and the at+cipstart. the responsabile for the implement of this project, tell-me that is impossible, he must use every time the two previsous commands. My question is if there are a way to do this. My last invoice for communications was something like 1.640,00 €. Becou my operator taxes the minmimium of 1024 kb.
Thank you
