JN-AN-1124 JN513x Periodic Recalibration

The JN513X device features an integrated radio, which is calibrated at startup for optimum performance. In applications with a significant variation in temperature (e.g. >40degC) 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 library function, which can be called to test the temperature using the onchip temperature sensor, and triggers a recalibration if there has been a significant temperature change since the previous calibration.
