    Hi,

    The below is my setup:
    Model - 4in1 micro esc m0129
    Firmware - 39, hash fb6fd95
    Bootloader - 184, hash 10bf24c8

    modal_io.cpp
    parse_response()
    qc_esc_packet_process_char() - returns ESC_ERROR_BAD_HEADER

    I was wondering if there is a interface control document available for devs? Also has the byte communication changed in this version of ESC firmware?

    Thanks!

      Update:

      It was an issue on my end regarding the baud-rate configuration.

      All is good.
