Android Question equipment needed for two phones to communicate via LoRa

[toby]

I want to build a simple app that lets two phones, which are 5kms apart at maximum, communicate via LoRa with each other directly without Wi-Fi. Could someone provide a list of required equipment (excluding the phones) and show me where I can order them?

TIA

The app can be a B4A, or B4R which has a LoRa library already.

My project is related to @freedom2000's weather station in that both use the LoRa to communicate. Mine would be much simpler as all I want is to allow two phones to have a direct connection over a relatively long range

I don't have these so you will have to determine if they meet your requirements.
The description sounds interesting - there are also some videos.
