aRFR Cannot Connect on One Device but Can On Another


If you have multiple aRFR apps running in a system you may find that some devices can establish a connection to the console, while others cannot on the same network.

Explanation of Issue

We have found that while some Android devices can use their data connection for talk and their Wifi connection for the app, others cannot.  Specifically we have seen this happen on Essential Phone in the field, but it could be possible on other devices.  The Android device attempts to connect via its data connection and thus can never see the console.


  1. Place the device into Airplane mode and re-enable Wifi, then connect.
  2. Temporarily disable the data connection on the device settings.
