Bluetooth timecode too long? (SOLVED)

https://documents.blackmagicdesign.com/ ... ontrol.pdf

Code: Select all

Timecode (encrypted)
UUID: 6D8F2110-86F1-41BF-9AFB-451D87E976C8

Did anyone use this Bluetooth Low Energy Characteristic of the Blackmagic Camera Service?

The documentation says It is a 32bit number in Binary Coded Digital.
However I get 12 bytes.

BCD decoded it reads "15150800000904030202050100"
while the timecode showed "00:02:51:00" when looking over to the camera.

Does anyone have an idea?

I think I found a solution while replying to an email from support.

Hi Marcus ! I'm feeling jealous of how far you already got haha !
Was that on linux or mobile ?

I am trying to make a similar project for my use from a linux machine but while I managed to read NON encrypted characteristics values, I have NO IDEA about how to access the encrypted UUID characteristics.

Would you mind sharing your procedure ?

Thanks a lot !

Both. it is Android and obviously Android runs on a Linux kernel.
There is no encryption in this protocol.

I am aware of this, My point is that while I’m succeeding at pairing a phone (both android and iOS in their respective language), I’m stuck at trying to pair my raspbian machine.
When I read public characteristics, all right !
But when I try to initiate binding by writing « camera on » to the correct UUID, it will just fail. Pretty sure I’m not far at all but I’ve been stuck for days , which is why I was hoping that you succeeded and would be ok to share the commands

Can't help you with that. Sorry.
OS Bluetooth API takes care of all that.
