My goal is to send GPS coordinates from Arduino to remote server using SIM900A.
This docs simply states how to connect to remote server. From the time-gap of 3 days, it worked only once, I mean the command
AT+CIPSTART="TCP" , "mydomain.tld", "80"
gave result as OK only once but afterwards, it kept on giving ERROR as output.
How to ahead after this ? How to solve this issue ? I am totally new in Microcontroller Programming.
How to make HTTP request ? I googled for SIM900A AT commands and SIM900A AT datasheet but did not find anything.
