Making a dual radio repeater

  • Hello everyone,
    I would like to make a repeater with tow radio, because my gateway is 2.4Ghz, but i wan't to put outdoor sensors in 433Mhz.

    BUT: as i'm not english native, i may haven't found the keyword to find this kind of project into the forum, is there anything like this ?

    Thanks, and have a good day !

    Dual radio is not (currently) supported. The supported solution is to use one gateway per radio network.

    So just create two gateways, one with nrf and one with rf69.

  • Thanks for the answer.
    May we trick and use two arduino talking via serial ?
    My controller doesn't support two gateway yet.

    Yes that should be possible. String parsing in c/c++ is a pain (imho) though :(

  • Too bad, way out of my ability...

    @mfalkvidd strtok makes it easy ;-)

    e.g. quick guide

  • Not sure if it is an option for you or not but, could you have one of your radio networks work via serial and the other on MQTT?

    The RFLink (433mhz) has a great PCB (for Mega though) that has both Nrf24+ slot and 433 transiever slot - but at this moment the only thing implemented is the 433mhz function - so its a bit of work.
