To test if your module is performing correctly, place the module about one meter off the ground using a milk crate, 5-gallon bucket, or something similar in size. Measure your signal from approximately 100 ft. away, and you should see a signal quality of about -45. In the event you are seeing a signal greater than -45, please reach out to COBRA support, as additional testing will be requested to determine if there is a fault.
If you are running firmware version 5.0.2 or higher, make sure only one module is powered on during this test because the MESH network will give you inaccurate results otherwise.
