Wireless IoT Development Platform for 4G LTE (RDA8910, ASR1601, ASR1603), GSM (MT2503, MT6261, RDA8955) & NBIoT (MT2625) Chipsets.

SIM800L, SIM800C and SIM800H GSM module library for the Raspberry Pi to send, receive, delete SMS messages, perform HTTP GET/POST requests and many additional queries

Easy library for interfacing with mobile modems

Python REST api for the Waveshare SIM7600

CLI tool to communicate with SIM modems by abstracting AT commands

This project demonstrates how to receive SMS messages using a Raspberry Pi Pico and a GSM module. The code provided here allows you to interact with a GSM module (A7670C) and receive SMS messages. The received messages are then sent to a specified Telegram chat using the Telegram Bot API.

This project consists of a python script which tests SIMcom SIM800H module over COM/ttyXX port.
