[172] RADIO: BLE long range co-channel performance

This anomaly applies to IC Rev. Engineering C, build codes CKAA-CA0, QIAA-CA0.

It was inherited from the previous IC revision Engineering B.


Packet loss when a blocker signal is present.


BLE long range (Ble_LR125Kbit or Ble_LR500Kbit). Blocker signal present at the same or nearby RF frequency.


Fails BLE test with co-channel interference (RF-PHY/RCV/BV-29-C) without FW workaround.


Workaround is incorporated into S140 SoftDevice v6.1.1 and the DTM example in SDK v15.3.0. See the following document for a description of the workarounds:
