First I am in Mexico. I want to connect the SIM800L module to the cellular network to be able to make HTTP requests with GET and POST, I have an AT&T chip. But I can't perform the initial configuration, these are my commands.
AT + SAPBR = 3.1, "CONTYPE", "GPRS"
AT + SAPBR = 3.1, "APN", "INTERNET"
AT + SAPBR = 1.1
AT + SAPBR = 2.1
AT + CLTS = 1
I hope you can help me, or comment if someone has managed to communicate for HTTP.
Thanks and regards
you need to read response coming from your sim800L for each each AT command sent
and you need to post your code here ( with code tags )
I tell you that I have connected the module directly to the PC by UART. My specific question is towards the AT command "AT + SAPBR = 2.1" because it does not assign me an IP address.
So, when using AT commands to make HTTP requests it always generates an error on the network. There is something wrong with the network configuration and I don't know what it is, I hope you can help me.
Thanks and Regards
