[Feature request] Using key lighting programmatically.

[aminehmida]

The idea is to offer an easy way to access keys lighting programmatically (API?). This will allow cool stuff like receiving notifications visually on the keyboard like flashing "m" letter if you receive an email etc ...
I hope this can be easily implemented in this firmware and thank you in advance if you consider this :)

That is a nice idea and shouldn't actually be all that difficult as there's already a protocol in place to talk to the keyboard over bluetooth. See for example @fcoury s https://github.com/fcoury/node-anne-pro

Thanks for the suggestion, will have a look once the basics are working.

+1 👍 There are some key lighting implementations I've considered working on but pushing full layout updates over Bluetooth seems inefficient

If possible I would love to see some functionality to do this over USB to eliminate the need for Bluetooth pairing if you just want to 'plug and play'

Thanks for your work on this! I'll try to get more familiar with Rust and STM32 to give more constructive suggestions or commits

Not implemented at all yet, but there is a message that changes the LEDs for a set of keys, see here: https://github.com/hi-a/annepro-key#sample-messages

09 35 0b ca 0a   type:9  size:53 cmd:11      ?:202 keys:10
00 ff ff 00 01   key:Esc color:Y
01 00 ff 00 02   key:1   color:G mode:flash
02 ff 00 00 01   key:2   color:R
03 ff 00 00 01   key:3   color:R
04 ff 00 00 01   key:4   color:R
0c 00 ff 00 01   key:+   color:G
2f 00 ff 00 02   key:B   color:G mode:flash
0b ff 00 00 01   key:-   color:R
0a 00 ff 00 01   key:0   color:G
1d 00 ff 00 01   key:A   color:G 

message header 09 35 0b
command header ca 0a
Payload format => key:byte color:3bytes mode:byte

Basically you send message 9/11 and then a list of keynr and colour/mode.
Would be nice to have this all a bit more documented.
