Starting and stopping video with BLE requests (HERO9)

[jacobstasiewicz]

Problem:

I am trying to find the bluetooth requests to start and stop the recording of my gopro 9, I already have figured out how to control video settings with gatttool. Is there a cheat sheet anywhere? Or could someone explain to me how to find the requests for certain commands, I am new to this and all I can figure out how to do is change the camera resolution. This page https://github.com/KonradIT/goprowifihack/blob/master/Bluetooth/ArchLinux.md is not working

Details:

• GoPro Camera(s): Gopro 9
• Firmware Version: 01.00
• Steps to reproduce: NA
• Happens every time? [Y/N]: Y

I having a tough time figuring out how to convert the Requests section from https://github.com/KonradIT/goprowifihack/blob/master/Bluetooth/bluetooth-api.md to bluetooth requests

[KonradIT]

To start and stop video send the following byte array:

Start: 3,1,1,1

Stop: 3,1,1,0

And to use with gatttool, copy the command as specified here: https://github.com/KonradIT/goprowifihack/blob/master/Bluetooth/Platforms/ArchLinux.md

I am still having a tough time I can connect to my camera and change settings with char-write-req __________ perfectly fine but when I try to use char-write-req 38 03010101 to start recording, gatttool reads " characteristic value was written successfully "but then the camera wont record
