Hello, there may be examples of using LoRA WAN to transmit messages. Now we have organized the collection of information from mobile devices within the radius of WiFI access point. But we need to receive information from(short messages) from fixed mobile devices within a radius of 1-2 km. I use LoRa WAN USB OTG transmitter and gateway. I need to organize the exchange of data between devices at a distance of 1 km, in a remote area where there is no cellular coating and a wipes. I do not want to use the RS232 wire to solve this problem and I don't want to do all this with Arduino
