BLE scanner working via GAP_OBSERVER_ROLE

Hi Sir/mdm,

I'm now working on the bluetooth section's code and require some technical support.

End goal is to get the BLE scanner working via GAP_OBSERVER_ROLE to extract BLE advertising(filter by company identifier and major/minor)

Here is the issue and question:

1. I cannot locate any information on GAP_OBSERVER_ROLE setup and application notes for aci_gap_start_observation_proc_process step by step configuration. Below documentation did highlight some info on GAP_OBSERVER_ROLE but very little info is disclosed.

2. Alternative if the question 1 is not an option, I will use the direct test mode to remote the BLUENRG-2(not a good option as it will make customization option complex). I tested the setup via BLUENRG GUI but the provided solutions via following document is not working when I tried to sent the ACI_GAP_INIT, the STEVAL-IDB008V1M unit not giving response.

I have attached the BlueNRG GUI setup for your reference.

Please start with clicking "Init Device" button in BlueNRG GUI.

Then the BlueNRG-2 shall be ready to observe BLE advertising packets with ACI_GAP_START_OBSERVATION_PROC.

After executing ACI_GAP_START_OBSERVATION_PROC, the scanned packets are reported in HCI_LE_META_EVENTs, with Subevent_Code equal to HCI_LE_ADVERTISING_REPORT_EVENT.

The procedure shall be terminated by issuing ACI_GAP_TERMINATE_GAP_PROC with Procedure_Code set to 0x80.

Attached my test on STEVAL-IDB008V1 (BlueNRG-2) for reference.
