I am looking for a way to access to configuration of Blheli-S firmware running on a Diatone Mamba F30Mini: enter image description here

It seems possible using :

There is explanation on different site about FC Passthrough. This seems to use connection to a Flight Controller. As I am planning to use an Arduino nano to connect to the ESC, I am wondering how to make the connection.

Is it possible to connect more or less to connect the ESC to a PC ? or connecting through the arduino ?

    $\begingroup$ I haven't tried either method because I've always done it through the FC, but the method described in this PDF (flyingmodscom.files.wordpress.com/2017/06/…) and this article (reefwing.medium.com/…) might help you here? $\endgroup$

  • $\begingroup$ @ifconfig Thanks, document seems providing good information. I need to dig into, to understand the ESC side connection, in its documentation there is 8 pins (GND, VCC, motor1-4, Telemetry & Curr) $\endgroup$

Thanks to informations given by @ifconfig, using BLHeliSuite connecting :

  • GND to Arduino GND
  • ESC1 to Arduino D11

It allow to upload to Arduino the "Arduino Bootloader" enter image description here

Then selecting "ATMEL BLHeli Bootloader (USB/Com)", and go to "ESC Setup" tab enter image description here

Finally quite straight-forward, with a tool that may be more user-friendly.
