    Hi User,
    When waking from sleep and turning on the CC, the write must synchronize to the timeline of the device, then the device must have 250 ms to acquire the value. It may take approximately 500 ms from wake to have a valid value. Once a value is present it will be updated every 250 ms, reads between that interval will return the last value.
