How can I achieve optimal range for LoRa node-to-node communication? I’m using the RFM95 module at a frequency of 932 MHz but experiencing very poor range—data transmission cuts out at only 4 feet. I have a compatible antenna, which is properly soldered as well.
Probably by asking on another Forum!
