Модуль RTL8822CE BT-WiFi не отображает список устройств Bluetooth во время сканирования. Но Wi-Fi работает отлично

Я использую NVIDIA Jetson TX2 NX с модулем WiFi-BT на базе чипа RTL8822ce. Bluetooth может открывать и видеть каждую деталь, но при запуске сканирования он не будет отображать ближайшие устройства.

Но когда я взял журнал, я заметил некоторые проблемы в порядке команд HCI.

После шага включения сканирования вы можете увидеть, что команда HCI: Запрос не отправляется. И когда сканирование отключается, HCI Command: Запрос отправляется. То есть есть разница в порядке команд и последовательности событий.

Могу ли я изменить последовательность? Вы можете помочь мне решить проблему?
