@scaramanga have you checked the product listing and documents on the M5Stavk website?

@felmue said in M5Stack Core Basic as Meshtastic Device:

Hi guys

I don't think you can use pre-compiled Meshtastic firmware as some GPIOs used in pre-compiled firmware cannot be selected in LoRa868 V1.1 module.

From the M5Stack Meshtastic variant.h file and the previous LoRa module I understand the following GPIOs are used:

SCK : GPIO18 MISO : GPIO19 MOSI : GPIO23 CS/NSS: GPIO5 IRQ : GPIO36 RST : GPIO26

However the newer LoRa868 V1.1 module doesn't allow to select GPIO36 as IRQ nor GPIO26 as RST.

So I think you either need to compile Meshtastic firmware (with the correct GPIOs) yourself, get the older LoRa868 module or modify the V1.1 hardware.

Note: I do not have the necessary hardware to test this myself - so my above conclusions could be incorrect.

Thanks

Is there an answer from M5Stack specialists?

Hello @HappyUser

the code works for me using M5Core2v1.1 and the following modifications:

//#include <M5Core2.h> <-- replace this with below lines #include <M5Unified.h> #include <Wire.h> M5.begin(); Wire.begin(); <--- add this after above line

Thanks
Felix
