Thanks a lot for the suggestion . Now its executing only once . But if in case i have to send a data , i use a function
send_data(args);
while(1);
now my intention is to wait for another data to come from the other end . and now that there is a while(1); do you think it is possible.
I send AT only once
I have to wait for OK
in the waiting period how do stop my 8051 from re-executing
I hope u understood my problem
and thanks a lot in advance
