hello
I made a bluetooth thermometer for Arduino.
I want to display the temperature by connecting it to my Apple Watch 5.
Can I make an app on my own with the Apple Watch? (only apple watch)

watchOS supports CoreBluetooth (albeit with some limitations). You can make an app and connect to your thermometer while the app is on the screen.

Your app will only be able to do this when it is running in the foreground and the screen is on. It won't work when the app is no longer active.
