Im currently working on an app which needs simple communication between a bluetooth button (basically a selfie button) and the connected phone through the app. Now, i can connect normally with my phone and it does work as intended, but as soon as i want to achieve this communication via code im running into problems. I got the discovery of devices and can connect via their mac adress. The device is a no name brand so there is no documentation on the UUIDS, but i have used ble apps to find out the UUIDS i need, or at least the ones i think i need. This is my current code when the device gets “clicked” in the device list. Im pretty new to this so i might be wrong but im basically trying to activate the notification by writing to the human interface UUID (on the physical button press)so i can later get notifications on button press to use for my app.Im trying this because simply trying to get communicate with the correspondant notification UUID hasnt worked so far. The whole setup notifcation part has yet to work. It would be a blessing if anyone was able to help me out here. Thanks in advance lads.
