getServices is empty after connecting, but before that the device shows it has services

I can find and connect to a device using BLE

In the scanresults, the device has services, but when the device connects (using pairDevice) then the device returned has no services - which is weird because the state of the connection at that point is successful, and its the same device

Im trying to connect with Arduino, so maybe the issue lies there?

Once you are connected (you have a device), you get the service with something like this:

service = device.getService(profileManager.MY_SERVICE1 );

where MY_SERVICE1 is the UUID you want to use.

That is a good question. Do you mean with the Garmin?

On the Arduino it should, the documentation says all characteristics support it (mine being the int type)

When the characteristic is defined on the Adduino side, you likely have to specify read, write, and/or notify.
