Hello,
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.
AT+SAPBR=3,1,"Contype","GPRS"
AT+SAPBR=3,1,"APN","net2.vodafone.pt"
AT+SAPBR=1,1
AT+HTTPINIT
AT+HTTPPARA="CID",1
AT+HTTPPARA="URL",myURL
AT+HTTPSSL=0
AT+HTTPPARA="CONTENT","application/x-www-form-urlencoded"
AT+HTTPDATA=110,10000
my message
AT+HTTPACTION=1
AT+HTTPREAD
AT+HTTPTERM
AT+SAPBR=0,1
However, when I try to do it by code, i get an OK for every command, but HTTPACTION fails to work, by returning:
"+HTTPACTION: 1,601,0"
I've triend different libraries, with codes such as "sendCmdAndWaitForResp" and already tried directly with serial.write(command).
I'm totally out of ideas.
Regards,
