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

This anomaly applies to IC Rev. Engineering D, build codes QIAA-DA0, CKAA-DA0.

It was inherited from the previous IC revision Rev 1 nRF52840.

Symptoms

Packet loss when a blocker signal is present.

Conditions

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

Consequences

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

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:
