Radio_03

LE 2M PHY Sensitivity vs Selectivity

Revisions Affected:

Revision: F and earlier

Details:

Some devices operating using the Bluetooth Low Energy 2 Mbps (LE 2M) data rate may experience increased Packet Error Rate (PER) for receiver RSSI input levels centered around -70 dBm with a narrow window of +/- 5dB.

Workaround:

Updated radio settings are provided starting with the SimpleLink CC13xx_26xx SDK v5.40.00 and are applied by default. These settings improve sensitivity while resulting in up to 4 dB degradation in selectivity.

To minimize potential PER impact, it is recommended to leverage the updated radio settings made default in the SimpleLink CC13xx_26xx SDK v5.40.00 and later SDKs. If the LE 2M PHY is not used, it is not required to use these settings and SDK migration is not required. For applications configured to use the LE 2M PHY, migration to the latest SDK to leverage these settings is recommended.
