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?
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
