I’ll use mostly Arduino Uno but will give more details about the differences between Arduino boards when it comes to Serial communication. This tutorial will work with a Raspberry Pi 4 (and earlier: 3B, 3B+) board, and any Arduino board. A basic example at first, leading to a more complete application using a Raspberry Pi, an Arduino, and other electronic devices. Then you’ll see how to setup your hardware and software, and we’ll dive into the Python code (Cpp for Arduino).

The module does not support hot swapping. This is only for upgrading firmware of SIM800. If SIM800 will drop off while working, please connect a external at least 5V/2A power supply to this micro usb. SIM800 resetting key: press the key, SIM800 will be reset. SIM800 powering-on key: Keep pressing the key for more than 1 second, SIM800 will be powered on keep pressing the key for more than 1 second after the board is powered on, SIM800 will be powered off. SIM800 network status: used to indicate network status, the working status of the indicator is as below: SIM800 status: When SIM800 works normally, the indicator keeps on. Power: When there is normal supply to the board, the indicator keeps on.
Go shopping RASPBERRY PI SIM800 GSM/GPRS ADD-ON V2.0(IMIM150720001) Feature Moreover, the module supports powering-on and resetting via software. AT commands can be sent via the serial port on Raspberry Pi, thus functions such as dialing and answering calls, sending and receiving messages and surfing on line can be realized. Raspberry PI SIM800 GSM/GPRS Add-on V2.0 is customized for Raspberry Pi interface based on SIM800 quad-band GSM/GPRS/BT module.
