Add scan function to ble_wifi_onboarding sample

[hi118]

Hi,

Since "STM32 Connectivity Expansion Pack 1.1.0" did not have an example of BLE scanning function, I am trying to implement scanning based on "ble_wifi_onbording".
The example I referenced to add the scan is "hello_client".

However, the result of p_scan_result, which stores the scan results, is NULL.

What are the possible causes?

I haven't changed the setting value of wiced_bt_cfg_settings from "ble_wifi_onbording", is that the reason?

Hi @hi118 :

Which API do you call?

If possible, please your log information or code to me for checking.

Best Regards,

Colin

Hi @Qi_Colin 

> Which API do you call?
Sorry for my lack of knowledge. what answer do you expect?

Code (app.c)
Functions and callback functions that call wiced_bt_ble_scan() from application_init() which is called after receiving BTM_ENABLED_EVT.

Log(log.txt)
It will be a log from the start until the scan result is found to be NULL.
The last line "Scan completed:" is the log output when the scan result is NULL for him.

I didn't see anything wrong from your code. Don't know why the scan result is empty.

Could you try the "Bluetooth LE CTS Server" demo which also demonstrates the BLE scan function?

It turned out that the cause was mixed paths of different modules in the optional include settings of IAR-EW.
Thank you for your cooporation.
