Thermometer sensor from phone to phone

How do one send thermometer data from phone to phone? I already got the app to read the thermometer. The reading of the thermometer works good. All I want is the second phone to read the first first phone's thermometer.


perhaps , it may depend on where the other phone is

  • use a CloudDB or FirebaseDB to send the templ then read the temp from the first phone to additional phones from the database.
  • send an email
  • send an sms text

If the other phone is near (within a few feet), there are other techniques that might be used. I haven't tried them. Possibly bluetooth. See Share files & links with Android devices near you - Android Help

The second phone is close and I'm using bluetooth.
