Hello everyone,
I tried to connect a sim800L to my Arduino Mega for HTTP requests. However the command AT+HTTPACTION=0 is not responding.

I enter the following commands and when I enter AT+HTTPACTION=0, I get only this response (no error and no confirmation)

the commandsare:

AT+SAPBR=3,1,"CONTYPE","GPRS"
AT+SAPBR=3,1,"APN","internet"
AT+SAPBR=3,1,"USER","ooredoo"
AT+SAPBR=3,1,"PWD","ooredoo"
AT+SAPBR=1,1
AT+SAPBR=2,1
AT+HTTPINIT
AT+HTTPPARA="CID",1
AT+HTTPPARA="URL","test.libelium.com/test-get-post.php?a=1&b=2"
AT+HTTPACTION=0

the responses are:

AT+HTTPPARA="CID",1

Finally, the error was a hardware error. The shield was restarting due to lack of power.
