Known Issues
| ID | Summary |
|---|---|
| OSPREY_LDB-1700 | Driver does not support iw power_save |
| OSPREY_LDB-1691 | Power consumption in Wi-Fi Idle connection (DTIM 1) is currently above target due to missing software optimization |
| OSPREY_LDB-1690 | Recovery process in Station role sometimes fails to re-connect to WPA3 AP |
| OSPREY_LDB-1688 | Wi-Fi/BLE COEX: In some cases Wi-Fi scan fails to find AP during BLE data |
| OSPREY_LDB-1685 | Multi-Role STA-STA: When both roles run UDP RX traffic, low throughput observed (on both) |
| OSPREY_LDB-1678 | Stability: traffic stopped after several hours of Bi-directional TCP Wi-Fi traffic |
| OSPREY_LDB-1668 | Wi-Fi/BLE COEX: Disconnection observed in stability test of Wi-Fi traffic with BLE Advertise |
| OSPREY_LDB-1641 | Interoperability: Some Degradation on RX with Xiaomi AX1800 and TP-Link AX11001 APs |
| OSPREY_LDB-1638 | Some beacon-loss observed when setting LSI to 9 and running UDP RX traffic |
| OSPREY_LDB-1615 | Wi-Fi/BLE COEX: Instability observed in scenarios of Wi-Fi Multi-Role with BLE advertise |
| OSPREY_LDB-1580 | Wi-Fi/BLE COEX: Wi-Fi RX throughput is degraded when BLE connection interval is 50ms |
| OSPREY_LDB-1579 | Interoperability: TP-Link Archer C60 AP sends unexpected deauthentication to CC33xx while idle |
| OSPREY_LDB-1513 | Device will not connect to an AP in ‘mixed mode’ security since WPA (TKIP) is not supported |
| OSPREY_LDB-1498 | “iw” Linux-shell tool reports incorrect TX rate |
| BLE_OSPREY-178 | BLE: connection and pairing sometimes fails or takes very long with TI CC2652R1 peer |
