Advisory 09

Receive Sensitivity Degradation in Continuous Receive Operation Over Long Time

Revision Affected:

A and B

Details:

The CC1310 receiver uses an advanced and dynamic synchronization word search algorithm to optimize the reception of wanted packets and minimize false packet detection. If a CC1310 device operates in continuous receive mode for a long period of time, the dynamic synchronization word search algorithm might in some rare cases lead to unusually high internal threshold values and thereby degraded receive sensitivity. The sensitivity degradation probability depends on the operating noise and interfering conditions and the auto-correlation properties of the synchronization word.

Workaround:

Use SIMPLELINK-CC13X0-SDK_2.20.00.38 or later. For customers using an SDK that pre-dates 2.20, a restart of the receiver resets all internal threshold values and ensures optimal performance of the synchronization word search operation and best receive sensitivity.
