LoPy as a gateway send packet under TCP/IP



  • Hello guys,
    I am a now study LoPy and LoRa and I want to achieve an extension of server and client communicate using LoRa. The controlling PC able to send a packet of message to the client PC via LoRa. So this will achieve a long distance communicate using TCP/IP.
    Anyone can give some example or similar project like this.
    Thanks!



  • @jmarcelino said in LoPy as a gateway send packet under TCP/IP:

    don’t recommend running TCP over LoRa itself.

    Sir, can you please elaborate more on how to change the lora packet data into tcp/ip format?

    The duty cycle / dwelling time restrictions on sub-1Ghz LoRa frequencies don’t usually (for most contries) support using it for TCP/IP traffic. Also you can have very long transmission times (over 1 second) at higher spreading factors which don’t work well with TCP/IP.

    So really LoRa is meant to exchange short messages. You can however take the received messages, frame into TCP/IP and forward them over WiFi if you wish, just don’t recommend running TCP over LoRa itself.
