You can use the Thread range testing app, shown in the figure below, with your smartphone to verify and measure signal strength, see 'Related documentation'.
The workflow is:
- Install and open the Thread Range test app on your smartphone (Android only).
- Connect the Thread dongle to your smartphone.
- Pair the Thread Range test app to another Thread device (e.g. a TME).
- Monitor and log the Thread signal strength.
- Check Thread signal strength.
- If the Thread signal strength is strong enough: Write down the signal strength on your Thread network plan and proceed to the next device for the range test.
- If Thread signal strength is not strong enough: Adjust Thread network configuration or environment parameters and repeat the Thread signal strength test.
- Save the Thread signal strength log.
- Export the Thread signal strength log and add it to project documentation.
