// Moteino gateway/base sketch that works with Moteinos equipped with RFM69W/RFM69HW/RFM69CW/RFM69HCW
// This is a basic gateway sketch that receives packets from end node Moteinos, formats them as ASCII strings
// with the end node [ID] and passes them to Pi/host computer via serial port
// (ex: "messageFromNode" from node 123 gets passed to serial as "[123] messageFromNode")
// It also listens to serial messages that should be sent to listening end nodes
// (ex: "123:messageToNode" sends "messageToNode" to node 123)
// Make sure to adjust the settings to match your transceiver settings (frequency, HW etc).

You can’t perform that action at this time.
