Connection or communication errors with Data Simulator and System Devices


Applies To:

groov View running on:

  • GROOV-AR1, GROOV-AR1-BASE, GROOV-AR1-SNAP
  • GROOV-AT1, GROOV-AT1-SNAP
  • GROOV-SVR-WIN, GROOV-SVR-WIN-BASE, GROOV-SVR-WIN-SNAP
  • GRV-EPIC-PR1

Versions Affected:

R1.3.0 to current for GRV-EPIC-PR1
R4.1a to current for all others listed


Symptoms:

In groov View, your project accesses gadgets configured with both Data Simulator and System tags at the same time (normally because they are on the same page), your project may fail to communicate or connect to either or both. You'll see a sequence of messages similar to the following:

Nov 7, 2019 9:09:26 AM INFO com.opto22.groov.scanner.core.DeviceController - Connecting to device Simulator-1
Nov 7, 2019 9:09:26 AM INFO com.opto22.groov.scanner.core.DeviceController - Connected to device Simulator-1
Nov 7, 2019 9:09:26 AM WARN com.opto22.groov.scanner.core.DeviceController - An unknown error occurred while communicating with device System-1.
Note that the device that these messages indicate groov View is trying to connect to switches from Simulator-1 to System-1.

Resolution:

Opto 22 has resolved this issue and will include the fix in an upcoming release.
