Hey.
I found a description on how to operate the Sony A7RIII (and others). I manage to connect to the camera, but when I send a command according to :
Write to characteristic 0xff01
on service 8000-ff00-ff00-ffffffffffffffffffff
one of the following commands:
Focus Down |0x0107|
Focus Up |0x0106|
Shutter Down |0x0109|
Shutter Up |0x0108|
The camera doesn't respond in any way. Can you advise me?
Thanks
