3.1.7.1 Wi-Fi Service

The Wi-Fi service provides API’s to enable the following features:

1. Station mode
2. Soft AP mode

The Wi-Fi Service API prototype is as follows:

RNWF_RESULT_t RNWF_WIFI_SrvCtrl( RNWF_WIFI_SERVICE_t request, void *input)

It handles following services and reports the result to application over the return code or through the registered callback.

The following list captures the Wi-Fi callback event codes and their arguments

The following figure illustrates the Station mode connection sequence

Following is the example of establishing connection in the Station mode
