    Dear All,
    I’d like to set a spreading factor with OTA. It seems that when I set the datarate (with setTxDataRate function), it has no effect at all. Surprisingly when I connect in ABP I can set the datarate with setTxDataRate.
    Is this right or I my doing something wrong with OTA?
    Best,
    Steeve

    Do you mean to set the datarate used to perform the OTA join?

    The OTA join datarate is handled by the library.
    US915/AU915 alternates between DR0 and DR4 according to lorawan.
    The regions will cycle through available datarates for each join.
    This should allow a better chance of joining the network if many devices attempt to join at once.

    After the device is joined to the network the datarate can be adjusted according to the setTxDataRate input.
