Raspberry Pi SIM800L, SIM800C and SIM800H GSM module SIM800L GSM module library for Linux systems like the Raspberry Pi. This library was also successfully tested with SIM800C and should also support ...

Thank you for your interest in this project. Unfortunately, this project is no longer maintained as I no longer have a functionning SIM800L module. Additionally, the SIM800L doesn't support current ...

Because the SIM800L module is very flexible, a great GSM project design can be relatively simple. But there are a number of reasons for experimenting with more complex ideas, such as enhanced ...

It is very easy to build an “SMS-controlled relay” with the help of a cheap GSM modem module and a small microcontroller board. Here, I’m using the SIM800L and Arduino Nano V3 to develop a nifty ...

I've got a couple of SIM800L modules in remote devices that have been running for years. A few days ago both stopped registering with the (One NZ) network at the same time, and no longer connect at ...

This project aims to replace a SIM800 module with a BK A7670E (4G) module without modifying the original hardware configuration, if the size allows it The goal is to allow an update of the system ...
