Compatibility of LoRa Chips: Using SX1262 as Sender and SX1278 as Receiver #81

Closed khalidalbasheer closed 5 months ago

khalidalbasheer commented 5 months ago

I’m working on a project that involves LoRa communication, and I’d like to explore using different LoRa chip models. Specifically, I want to use the Semtech SX1262 as the sender (transmitter) and the SX1278 as the receiver. My goal is to achieve reliable, long-range communication between these two chips.

Is it feasible to pair the SX1262 and SX1278 in this way?

The SX126X and SX127X are compatible from SF7 and above.

The SX126X normally use a TCXO for frequency control and can be used at lower bandwidths than the SX127X.

These are limitations of the devices and nothing to do with this library.

So, based on your comment, I can send packets from SX126X to SX127X using your amazing library. I note that your library settings use SF7. The device I want to use is ESP32 board with LoRa SX1262 chip built-in. produced by Heltec Automation esplora

You adjust the LoRa settings to suit the application.

No issues with the library.
