I saw MicroPython lib for SX1262 at [GitHub - GereZoltan/LoRaWAN: Possibly complete LoRaWAN implementation in micropython with SX1262](https://github.com/GereZoltan/LoRaWAN). Is there anyone success using this lib with Heltec LoRa V.3?

Generally, there are some steps to try to integrate these components together:

Make sure the LoRa chip used by the Heltec LoRa V.3 development board is compatible with the SX1262 chip supported by GereZoltan’s library. **Heltec LoRa V.3 is usually equipped with Semtech’s SX127x series chip instead of SX1262.**

It is recommended to solve potential compatibility and integration issues through careful hardware and software debugging, as well as community support.

**Moderator highlight - this is totally incorrect - suspect use of AI + it’s a competitors product.**

The LoRaWAN library used does not seem to handle the mandatory MAC commands, until proven otherwise it should not be used with TTN as it will result in a downlink packet for each uplink (= DoS attack on the gateways near the device)

The last line looks typical of AI generative content - for very generic answers there is a place for others to go and use those tools - but for complex questions and for using as a post on forums, not at all.

Or perhaps it’s because it’s a competitors product because the facts are wrong.

Thank you for confirming my thoughts. It’s wrong advice.

Hopefully someone can make it work with ESP32 and keep improving it.
