JN-AN-1140 JN514x Periodic Recalibration

The JN514x devices feature an integrated radio, which is calibrated at start-up for optimum performance. In operating environments with a significant variation in temperature (e.g. greater than 20oC) due to diurnal or ambient temperature variation, it is recommended to recalibrate the radio to maintain performance. Recalibration is only required on Routers and End Devices that never sleep. End Devices that sleep when idle are automatically recalibrated when they wake.

This Application Note includes a software function library which can be used to test the temperature using the on-chip temperature sensor and trigger a recalibration if there has been a significant temperature change since the previous calibration.
