I want to use IDB05A1 as BLE Observer, but I am not able to find any proper documentation to setup IDB05A1 as Observer. I request to help me.

I am using NUCLEO-F446RE MCU, IDB05A1 BLE Module, STM32CubeMX and SW4STM32 software.

Please use

1. ACI_GAP_INIT with the parameter Role also set Central (0x04)

2. ACI_GAP_START_GENERAL_DISCOVERY_PROC

3. Listen for HCI_LE_META_EVENT reporting advertising packets: HCI_LE_ADVERTISING_REPORT_EVENT

@Winfred LU Thank you so much for the answer. I used this answer along with The BlueNRG-MS Bluetooth® LE stack application command interface (ACI) and BLE 4.1 protocol document to setup the device as observer and central.
