Just wondering if two nodes (different frequencies) can communicate over the GPIO TX/RX serial port and pass traffic?
Example: Node 1 915Mhz
TX/RX
RX/TX
Node 2 433Mhz
No, this is not possible with stock firmware. If you don’t want to customize Meshtastic firmware with this feature, it would require a co-processor in between the nodes to route packets via Serial data between them. Suggest using separate UART connections between co-processor and each node.- ted
