Errata Related to Radio, #143, #102, #106, #107, #107

Justin

Hi,

I am using nRF52832 along with Softdevice 6.0.0, SDK 15.0.0, Chip Revision 2 (QFAA-EX0)

I am looking into Erratas and working on the possible workarounds. However  Radio related workarounds cannot be done in application code as its being used in softdevice.

So can you please clarify if the following erratas are addressed in Softdevice or if it all it is softdevice is susceptible to these erratas?

Errata 143 - False CRC Failure on Specific Addresses.

Errata 102 - Payload/end events delayed or not triggered after address.

Errata 106 - Higher CRC error rates for some access addresses.

Errata 107 -  Immediate address match for access addresses containing MSBs 0x00.

Errata 204 - Switching between Tx and Rx Causing unwanted emissions.

I am asking these questions as softdevice is like a black box for me and do not know if these erratas are applicable.

Thanks,

Justin

    Hi Justin, 

    Errata 143 - False CRC Failure on Specific Addresses.

    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. 

    Errata 102 - Payload/end events delayed or not triggered after address.

     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. 

    Errata 106 - Higher CRC error rates for some access addresses.

      Errata 106 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. 

    Errata 107 -  Immediate address match for access addresses containing MSBs 0x00.

       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.  

    Errata 204 - Switching between Tx and Rx Causing unwanted emissions.

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

    Best regards

    Bjørn
