Logging additional external data from ESP32 (or Arduino MEGA) to a STM32 FC

Hello. Can some one explain how to log additional external data from Arduino based boards to STM32 FC?

I think that i have to create a new log message (Adding a new Log Message — Dev documentation)
But i have no idea how to send data and trigger it via MAVLink

-- Reads data in from UART and logs to dataflash

-- find the serial first (0) scripting serial port instance
local port = serial:find_serial(0)

if not port then
    gcs:send_text(0, "No Scripting Serial Port")
    return
end

-- begin the serial port
port:begin(9600)
port:set_flow_control(0)

-- table for strings used in decoding
local log_data = {}
local term_number = 1
local valid = true
local term

I already did it waith lua. But I want to avoid lua using because of not avery board support it

Look for a Mavlink based device (like AP_Rangefinder_Mavlink) and write your driver based on that.

Tanks for idea)
I tried to build AP_Logger_Test, placed it in ardupilot/Rover directory. And, the build process is faced with a fatal error.
How will it be correct to build such custom scripts?
