I've been able to make a HTTP post though gprs with SIM800L, however, i've been only able to do it by manually input the commands on the serial monitor.
However, when I try to do it by code, i get an OK for every command, but HTTPACTION fails to work, by returning:
I've triend different libraries, with codes such as "sendCmdAndWaitForResp" and already tried directly with serial.write(command).
I'm totally out of ideas.
'+HTTPACTION: 1,601,0' means network error. Have you tried all the possible solutions to be found on Google?
Yes, the strange thing is that i am able by inputting manually the commands on the serial monitor. When I try to code the commands everything works untill the actual posting.
