[Symbolls]

Hello i have a galaxy watch that can control a power poin or libre power point from an app and i want to caputre the bluethoot signal sent from the watch and use it to control somthing else whith code how do i intercept or is it a beter way to make buttons on the watch that can control gpio pins on a raspi

It would be easier to create a wear OS app that will either connect to your pi via bluetooth or even better send a request over the network to a server running on the pi; you will be able to trigger it from anywhere. 

 

Afaik capturing the signal isn't difficult, but then you'll need to reverse engineer the commands being sent and send the "next slide" command yourself or whatever command you want to use. This may not even work depending on how commands are sent or if there's authorisation involved. 

 

If you simply want a button on your watch to be received by your pi, create your own button. However, if you want the challenge then sniff the signal. It sounds like a lot of fun.
