Hello,
Below is the sequence of commands that i have implemented in software for GSM 800C module acting as client.
I am trying communicate between server and GSM.(the data im receiving is plain text)
AT+CFUN=1
OK
AT+CSTT=“airtelgprs”
OK
AT+CIICR
OK
AT+CIFSR
Local IP
AT+CIPSTART=“TCP”,“IP”,PORTNUMBER
OK
CONNECT OK
AT+CIPSEND
after that i am checking uart interrupt for incoming data from server.
I am using hercules as a means to send data to GSM. I am receiving message sent through hercules in the terminal.
the issue is i am able to send or recieve data only for short period of time. after that it is going to hang state and does not respond to any commands or received messages.
is there anything wrong in command sequence or did i miss any commands?
how to have stable communcication between server and GSM for longer periods.
Thanks in advance
