WIFI_SCAN
Initiates a Wi-Fi scan. When the scan has been completed, the configured scan callback
function (see above) will be called. The callback function must have already been config-
ured before using this command. A Wi-Fi scan will interrupt the network connectivity
briefly since the scan must iterate through the channels on the wireless network.
WIFI_STATUSGET
When using this command, you must ensure there is enough space for the entire data
structure. Be sure the data pointer points to a buffer that is large enough to hold
sizeof(wifi_status)
This command returns status information into the user-supplied buffer (or data structure)
area. The
The structure elements have the following definitions.
