Hi Justin,

[quote user=""]Errata 143 - False CRC Failure on Specific Addresses.[/quote]

The address that are affected are not valid Bluetooth Low Energy address. Hence, this errata only applies to proprietary protocols using the 1 Mbit/s and 2 Mbit/s Nordic proprietary and Bluetooth Low Energy radio modes.

[quote user=""]Errata 102 - Payload/end events delayed or not triggered after address.[/quote]

Errata 102 has been fixed in hardware in nRF52832 revision 2, see Fixed anomalies in the nRF52832 Revision 2 Errata.

The workaround is enabled in SoftDevice SoftDevice S132 v4.0.2 and later. From v6.0.0 the S132 will automatically detect if its running on a revision 1 or revision 2 IC and enable or disable the workaround accordingly.

[quote user=""]Errata 106 - Higher CRC error rates for some access addresses.[/quote]

Errata 106 has been fixed in hardware in nRF52832 revision 2, see Fixed anomalies in the nRF52832 Revision 2 Errata

[quote user=""]Errata 107 - Immediate address match for access addresses containing MSBs 0x00.[/quote]

Errata 107 has been fixed in hardware in nRF52832 revision 2, see Fixed anomalies in the nRF52832 Revision 2 Errata

BLE addresses are not affected, hence no workaround applied in the SoftDevice.

[quote user=""]Errata 204 - Switching between Tx and Rx Causing unwanted emissions.[/quote]

The SoftDevice will call DISABLE after TX and RX, it will not switch directly from TX to RX.

Best regards

Bjørn
