In this tutorial we will try to make HTTP or GET request directly from arduino to SIM800L using AT Command with Serial Monitor.We will use the basic of AT co.

OK, power is solved. But what will be the brain of this operation To satisfy my desire to have portable weather station I've decided to go with LILYGO T-Call version 1.3, later on version 1.4 module with ESP32 and SIM800L module. LILYGO module comes with antenna and wires for power. Espressif ESP32 > will be the brain which will contain program. Hey guys,we are working with the sim8ool and raspberry pi pico on micropython thonny, the aim is to send an alarm notification using the raspberry Pico PI (on Micropython) and a SIM800L GSM Module. We have successfully tested the AT commands on the SIM800 using Thonny (on the shell Terminal) and have managed to send an SMS using AT commands on.
A comprehensive SIM800 Series library
for simplified and in-depth chip access. This library provides wrapper methods for all AT commands defined in the official SIM800 manual, many helper methods to work with returned replies, advanced serial timeout functionalities, and also methods to directly communicate with the chip. In this project we&x27;re going to create an SMS notification system with the T-Call ESP32 SIM800L module that sends an SMS when sensor readings are above or below a certain threshold. In this example, we&x27;ll use a DS18B20 temperature sensor, and we&x27;ll send a text message when the temperature is above 28C. Once the temperature has decreased
. SIM800L sends back the same AT command String that was sent to it from ESP32. Ask QuestionAsked yesterdayActive yesterdayViewed 37 times0. My objective is to send the command AT to the SIM800L board
and receive an OK.The problem is the data being received through the serial is exactly the same that was sent to the SIM800L module the received.
