1 — PL_WLN_EVENT_DISASSOCIATED: Wi-Fi interface has been disassociated from the wireless network.

Details

Multiple on_wln_event events may be waiting in the event queue. For this reason, the doevents statement will be skipped (not executed) if encountered within the event handler for this event or the body of any procedure in the related call chain.

On the WM2000 and WS1102, if wln.autoconnect is set to 1 — YES, association with a wireless network will trigger the generation of the on_wln_event handler with PL_WLN_EVENT_ASSOCIATED as the value of the wln_event parameter. If wln.autoconnect is set to 0 — NO, association with the network will not trigger the event handler's generation.
