Hello everyone,

I’m working on a project using SIM800C with NodeMCU V3 (ESP8266), and I need help with the following:

  1. Forward Incoming SMS to Telegram:
    I want to forward any incoming SMS to my Telegram account automatically.

  2. Send SMS via Telegram Commands:
    I want to send an SMS using a Telegram command (via the Telegram bot), which will trigger the NodeMCU to send an SMS from the SIM800C module.

I need help with:

How to read and forward SMS from SIM800C to Telegram.

Sending an SMS via Telegram commands using SIM800C.

The libraries I should install when uploading the sketch to Arduino IDE for NodeMCU V3 and SIM800C.

If anyone has any sample code or advice on setting up the Telegram bot API, please share!

Thanks in advance!

The best way to learn is to look at the sample code that comes with the libraries. Also, the idea of doing small parts of a larger project and getting that working before integrating them is a common recommendation here. Pick one to start, then research what libraries are available. Look at the library's github page to see how recently it was updated, how many issues are outstanding, and whether the author is a company like AdaFruit or a random guy with one library. Pick a few of the same, such as Telegram, and try a couple of samples.
