Bluetooth commands

Open demiantres opened this issue 5 years ago • 2 comments

The commands from https://gethypoxic.com/blogs/technical/gopro-hero5-interfaces and https://github.com/KonradIT/gopro-ble-py/blob/master/main.py differ (Konrad's values do work). For instance gethypoxid: SHUTTER_ON(new byte[]{(byte) 1, (byte) 1, (byte) 1}), vs. bytearray(b'\x02\x01\x01') (Konrad).

Why is this difference/how can the hypdoxid values be correctly converted?

The first byte is the length of the packet. 2 (length of ==>), 1, 1

I believe the commands seen here are of length 1 (simple command, like power off or tag), length 3 (stuff like locator or shutter) or length 5 (sub-mode change). Here are some examples, sent via gatttool: 0104 = Power Off everything including BLE 0105 = Power Off but leave BLE on until timeout 0301 0100 = Shutter Off (command length = 3, length of 1st param = 1) 0503 0101 0102 = Night Shot Photo mode (command length = 5, length of 1st param = 1, length of 2nd param = 1)
