  3. Start the Berty app.

  4. Make a contact request:

    • if the second phone received it, BLE connection works. You can chat between devices over BLE.
    • if the second phone didn't receive it, you should wait more time that BLE drivers retry connections. You can also stop/start the Berty app and check if the contact request is correctly received.

Other things to test

Permission system

  • Disable mobile data and Wifi.
  • After the onboarding process, try to refuse one of:
    • the permission explanation popup
    • the system permission system
  • Check that the BLE driver didn't start
  • In the Bluetooth screen, try to enable/disable the Bluetooth driver when the permission is not granted:
    • if the permission can be requested again, you should see the same popup that in the onboarding
    • if the permission is blocked, you should be redirected in the app setting to granted manually the location permission

Bluetooth setting screen

  • In the Bluetooth screen, try to enable/disable the Bluetooth driver.

Infra testing tool

[ToC] Summary The goal would be to have a simple config file in which we can define which peers we want to instanciate, their specifities, the test they will run and a simple way to launch a test run. Also we need a way to centralize all the logs from these nodes so that we can process them, the processing will be done by the Berty team. No need to develop a graphical interface to select the different parameters, the tool will only be for devs and nothing better for us than text files that we can easily copy, modify, version, etc... Basically, the needs would be to have the possibility to:
