QUESTION: How can I check Wi-Fi connection?

Actually there is a very important variable called WFStatus. Its value is directly dependent on Wi-Fi

connection status, and can be (them are defined in Hwlib.h):

• NOT_CONNECTED

• CONNECTING

• CONNECTED

• CONNECTION_LOST

• CONNECTION_FAILED

• STOPPING

• TURNED_OFF

Those values defines different statuses, and different “jobs in progress”.

The status “NOT_CONNECTED” and “TURNED_OFF” are static status, and they can be changed only

with a user task input. “NOT_CONNECTED” occurs when a Wi-Fi connection is closed and there is no

need to open it. The “TURNED_OFF” status occurs when Wi-Fi module is turned off for power saving.

The other status items are dynamic and can change without user input, but by external events. In

fact,when a user tries to connect to a Wi-Fi network, the WFStatus changes from “NOT_CONNECTED”

to “CONNECTING”. This status shows that the Wi-Fi module is trying to connect to a network. If it

connects, WFStatus changes to “CONNECTED”; if it fails, it changes to “CONNECTION_FAILED”. If this

last status occurs the openPicus Framework automatically retries to connect to Wi-Fi network until

success is reached or the user stops the connection from the user task. If a connection is lost due to

network problems (for example no reply from router, or too much distance between Flyport and the

Wi-Fi device communicating with Flyport) the WFStatus becomes “CONNECTION_LOST” and the

Framework automatically retries to connect Flyport to the network.
