    @ajb2k3 thanks for confirming. It not so clear from the provided schematic.

    Do you know which pin on the AXP is providing boosted 5V? If I had to guess, I would say it is 'IPSOUT' but it is not so clear to me from the Schematic nor the AXP datasheet.

    Do you know the part number of the IC noted 'DCDC' in screenshot below?

    Please add solution to support 9-bit UART.
    It’s commonly used in SeaTalk protocol.

    Thanks

    Hi All

    I am stuck and a bit lost,

    1: M5Stack Core Basic
    2: LoRa 868 V1.1 Module

    I have a Core Basic and downloaded the Meshtastic Firmware from the browser flasher, All boots as it should and says "Critical Fault #3" Which looking up means it ca not see the LoRa Module.

    Now i have the module connected and it is still saying the same thing when it boots. The firmware seems to be all fine apart from this not seeing the added Module LoRa V1.1

    The module has pin switches and came with 1 / 5 / 7 switched on but this is where i am lost because i dont know what is right and how the pins should be as there is little information out here.

    Does anyone know what pin switches need to be set at or am i missing something else i have to do to make the to match up.

    Thanks in advance
    Craig

    @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
    Felix

    Is there an answer from M5Stack specialists?
