For a simple remote control application involving two MC boards I would like to use a simple UART over the air link, very low baud rate is no issue, but good range at low power would be nice. LoRa comes to mind of course, and premade LoRa UART modems do exist, but they are fairly expensive.So I stumbled over ExpressLRS modules, which might work.Using such 10 USD ExpressLRS modules, would it be possible to use them as simple bidirectional P2P transceivers?I read about AirPort Mode on those, and to set RX-as-TX Mode on one of them.Does anyone have experience with such a setup, or an alternative idea how to achieve a low cost P2P link?
