Legato Linux distribution (Yocto project)

Hello Everyone,

I have connected USB RTL8188 Wi Fi Dongle
and added code to establish Wi Fi connection by using Wi Fi service : le_wifiClient api
le_wifiClient_GetFirstAccessPoint()
le_wifiClient_GetNextAccessPoint()
le_wifiClient_Create()
le_wifiClient_Connect() etc

It is giving me error as below:

Hi ,

I am trying to connect to wifi using commands as follow:
$wifi client start
$wifi client scan
but it gave me error
> root@swi-mdm9x15:~# wifi client start
> successfully called start.
> root@swi-mdm9x15:~# wifi client scan
> starting scan.
> DEBUG: le_wifiClient_GetFirstAccessPoint ERROR

The list of WiFi available is not getting displayed .

Hi rups,
Kindly can you please stop any of the other Wi-Fi apps are running (wifiApTest, wifiClientTest,
wifiWebAp), and then can you please check it.

     You can also refer the document http://mangoh.io/wp-content/uploads/2017/05/4119378_mangOH-Green-Tutorial-Wi-Fi_r1.pdf

Best Regards,
