Known Issues
| ID | Summary |
|---|---|
| OSPREY_LDB-2124 | MR STA/STA - Some instabilities observed on long duration traffic scenarios |
| OSPREY_LDB-2048 | Power consumption: in 5Ghz band, DTIM 1 current is slightly higher then expected |
| OSPREY_LDB-1898 | [COEX]: External coex - In some cases Wi-Fi connection time is very long during external activity |
| OSPREY_LDB-1880 | TWT - Sometimes Wi-Fi throughput is lower than expected |
| OSPREY_LDB-1878 | Link adaptation algorithm is not fully optimized |
| OSPREY_LDB-1779 | Suspend: Does not work with kernel 6.1 and BBB |
| OSPREY_LDB-1727 | IOP-STA - CC33xx connected to Buffalo AP sometimes sends PS polls every beacon |
| OSPREY_LDB-1700 | Driver does not support iw power_save |
| OSPREY_LDB-1688 | [COEX]: In some cases Wi-Fi scan fails to find AP during BLE data |
| OSPREY_LDB-1638 | Some beacon-loss observed when setting LSI to 9 and running UDP RX traffic |
