    Hi,

    There are multiple ways of measuring something like this, for example you could measure from the moment you call the API to send the data in your application to the time that the data is received in the other device. Another way of looking at this could be to determine the time from the data starts being transmitted by the radio to the time the other device receives the data.

    If you just want a raw theoretical time then you can do the math using the data rate of TIMAC which is 250kbps, and the max packet length is 125 Bytes.

    Given that TIMAC is based on the IEEE 802.15.4 Specification it is not straight forward to come up with a fixed latency between 2 devices since there are some variables that can affect this such as:
    - Time that the clear channel assessment takes(this is not a fixed time, it depends on the noise in the environment)
    - No Ack retransmissions.
    - Data packet length
    - link quality
