The OPS states the maximum transmitter RF power accuracy to be +/- 4 dB. Does this imply that if the power is set to +4dBm it could vary from 0 dBm to as much as +8 dBm? What is the typical variation in power that should be expected? Is this accuracy applicable from chip-to-chip or from BLE channel-to-channel or both? Under what specific conditions should it be expected that this variation of power level will be observed (temperatures, supply voltage variation, etc.)? This is a large variation and we need to better understand its impact to our predicted part-to-part communication range.
