The reason why these two HCI commands are broken for QCA controllers is that feature "Erroneous Data Reporting" is not enabled by their firmware as shown by below log: @ RAW Open: hcitool (privileged) version 2.22 < HCI Command: Read Local Supported Commands (0x04|0x0002) plen 0 > HCI Event: Command Complete (0x0e) plen 68 Read Local Supported Commands (0x04|0x0002) ncmd 1 Status: Success (0x00) Commands: 288 entries ......
