So you want to use the Dongle as a "regular" USB dongle scanning over BLE, correct? Please check out our BLE_app_uart_c example which can be used as a scanning device. However, ble_app_uart_c example uses UART instead of USB so it will require an additional USB-UART bridge to communicate with the Pi through USB. We don't have an USB version of this project but you can check out the USBD BLE UART Example and use that as a reference to how you can replace UART with USB.

Best regards,

Simon

BLE connection using bluetoothctl is not smooth when trying to connect my RPi4B with my laptop. WIth multiple retries, once in a while ble connection is successful. Watching btmon shows that the their is disconnection initiated but not much info available to pinpoint the cause of the problem.

not use the onboard ble available.
