    The Send method in the mDot.h file has this comment:
    — @param data a vector of up to 242 bytes (may be less based on spreading factor)

    I seem to be limited to 53 bytes / SF_9 125kHz.

    How is the spreading factor determined. I would have thought I would have set it on the mDot class.

    I want to be able to send 200 bytes.

    Thank you.

    See setTxDataRate() in mDot.h:
    https://developer.mbed.org/teams/MultiTech/code/libmDot/file/121e4c454964/mDot.h

    Also if ADR is enabled then the network server may change the datarate at the node. If this is not desired, which is the case with larger payloads then be sure ADR is not enabled.

    >>then be sure ADR is not enabled.
    I guess that is enabled/disabled on the Conduit?

    Thank you Jason.
