I also want to know。Could Raspberry Pi handle specific (custom) Mavlink messages？
Hi @qiuqiuggl, welcome to the forum!
This thread discusses custom mavlink messages being handled by the Raspberry Pi companion computer. Note that if you decide to use a custom message that you want to interface with ArduSub or QGroundControl then you’ll also need to modify and rebuild them so that they can handle the additional message type correctly.
Thanks!I will study this article and try to implement it, and let you know if it works well
