Arduino_To_Thingsboard

This is a working code which can send data to thingsboard.io from Arduino Mega 2560.

Harware Used:

1. Arduino Mega 2560
2. SIM900A / SIM800

Implementation Done:

1. Connected SIM900A / SIM800 to Serial1.
2. Read the output obtained from that over Serial.

reading rpc commands from thingsboard

hello, good job on the library. I have been trying to read commands from thingsboard but without success. I am using mqtt and i am able to publish data but not to subscribe or read from the server.
I am using this mqtt sketch https://bitbucket.org/mbari_peter/sim800-mqtt-ravi If you know how I can read messages from the server, let me know.

regards

Looping Issue

Hi,
When I use this program with my Simcom module, I'm getting stuck at the power_on loop and getting the following:

AT SIM ON AT AT AT AT AT AT AT AT AT AT GSM OFF AT SIM ON AT AT AT AT AT AT AT AT AT AT RGSM OFF

getStr always 0

Arduino_To_Thingsboard/Arduino_To_Thingsboard.ino

Lines 108 to 113 in 274b528

	getStr="POST /api/v1/"+ AccessToken +"/telemetry HTTP/1.1\r\nHost: demo.thingsboard.io\r\nAccept: */*\r\nContent-Type: application/json\r\nContent-Length:"+lengthOfJSON+"\r\n\r\n"+json;
	//TCP packet to send POST Request on https (Thingsboard)
	String sendcmd = "AT+CIPSEND="+ String(getStr.length());
	if (sendATcommand2(sendcmd, ">", "ERROR", 10000) == 1)

Hi,
I always get the AT+CIPSEND=0. Everything else works fine. Would appreciate if you can help me out. I'm a newbie.
