Advisory 08

Temporary Loss of Receive Function During Continuous Receive Operation Over Long Time

Revision Affected:

A and B

Details:

The CC1310 modem has a mismatch in the data rates between two modules. If a CC1310 device operates in continuous receive mode for a long period of time without receiving any packets, the mismatch might cause a temporary loss of proper RF reception. This temporary loss occurs at a rate which depends on operating frequency and data rate settings, and lasts for a short period of time before the receive functionality self-recovers.

Workaround:

Use SIMPLELINK-CC13X0-SDK_2.20.00.38 or later. For customers using an SDK that pre-dates 2.20, the operational mismatch between the two modules in the modem and the resulting temporary loss in the receiver can be avoided by updating the fractFreq value in the radio commands to generate correct settings for the radio.

SmartRF™ Studio v2.8.0 or later can be used to generate the correct fractFreq value for the radio at each operating frequency and data rate. This (new) fracFreq value can be directly applied to settings generated by older SmartRF™ Studio versions. Except for avoiding the temporary loss in the receiver, RF functionalities and performance are not affected by updating the fractFreq value.
