Router Role? (need more text here..)

Is there more details on Router mode? We want to place a device on the mountain above our city as most people will have a line of sight to it.

Would that be the best option if we place a device in Router mode?

Once the device is in Router mode, there is no screen, BLE or Wifi I understand. How do we know the device is working?

Thanks. I’ll try and decipher what you mean…

Where do I read more about the Router mode?

There is nothing else to read, that is all it does.
