wiced_bt_ble_scan is 8100 (pending)

[hi118]

Implemented "wiced_bt_ble_scan" based on [ble_wifi_onboarding].

But the return value of "wiced_bt_ble_scan" is always 8100 (pending).

The content of p_scan_result in the callback registered with "wiced_bt_ble_scan" is also NULL.

What do you think is causing this?

Hi @AnjanaM_61 

>Can you please let us know the parameters used for wiced_bt_ble_scan ? 
The arguments for wiced_bt_ble_scan() are as follows.
 ・BTM_BLE_SCAN_TYPE_HIGH_DUTY
 ・WICED_TRUE
 ・hello_client_scan_result_cback

>Also please let us know where are you calling this function in your code.
Referencing hello_client, set a timer with wiced_init_timer() at the end of application_init() and call it after confirming that wiced_bt_ble_scan_type_t is her BTM_BLE_SCAN_TYPE_NONE in the timer callback.

I have found that there is no problem with 8100 being returned from wiced_bt_ble_scan(), so I will close this question for now.

About the return of wiced_bt_ble_scan() I overlooked the following that was mentioned in the reference.

wiced_result_t
WICED_BT_PENDING : if successfully initiated
WICED_BT_BUSY : if already in progress
WICED_BT_ILLEGAL_VALUE : if parameter(s) are out of range
WICED_BT_NO_RESOURCES : if could not allocate resources to start the command
WICED_BT_WRONG_MODE : if the device is not up.
