Question about hardware compatibility

[langestefan]

Hi,

I have this board: https://www.waveshare.com/sx1262-868m-lora-hat.htm

Do you think it could work with this library? It seems to only support a UART based interface. On my module it says the type number is EBYTE E22 900T22S 1B. I have tried waveshare's supplied python code but it is very bad, their documentation is even worse. I can't even find a manual for this thing. I found a post on stackoverflow that says this board is not even using LoRa because it has a parameter called 'airspeed' which is not used in LoRa: https://stackoverflow.com/questions/73852442/lora-communication-between-rpi-and-pico-with-waveshare-hats.

Are all EBYTE modules this bad or is mine just special? Do you think I could somehow make it work with LoRa? I have tried the supplied python code and put it into receiver mode but it doesn't receive any messages from my LoRa transmitters (STM32WL's)

No, this library does not support LoRa module with UART interface like ebyte you have. I have tested some ebyte modules with SPI interface and they work fine.

Any LoRa module interfacing with SPI should works with this library. I suggest you use this ebyte module.

Hello, thanks for your reply. Do you think my module is a fake? If I look at the SX1262 datasheet it doesn't even have a UART interface, only SPI. This seems very fishy

No, it is not a fake LoRa module. I think the module has a microcontroller so it can interface from LoRa chip to UART. The idea behind the UART LoRa or LoRaWAN modules are similar to a GSM modem which has UART interface. Like a GSM modem, an UART LoRa module has some commands to control module operation which is similar to AT command.
