Hello,

While doing my PoC on the Wifi module, I see the following messageson the console :

+WIND:14:WiFi BSS Regained (0)

So far, I understand that's a loss of communication with the WiFi AP.

Sockets get 1/2 closed (can't be used, but not closed) and I get the mess in communication.

I have not found any mean to improve the situation.

Two questions :

- What are the possible causes of the messages Wind 30 / 14 ?

- What can I do to improve the situation ?

Thanks a lot

Hi Zirco,

BSS loss/regain are indication not relevant at production stage. Use wind_off_xxx variables to mask them.

Please note that BSS loss/regains doesn't means loss of connection with AP. When connection is lost, +WIND:33:WiFi Network Lost is raised after a BSS loss (not regained!). When a regain is not reached within 2 seconds from BSS loss, then WIND:33:network is lost.

Further info: you can delay BSS loss notification through wifi_beacon_loss_thresh configuration variable (0 means: never raise BSS loss). This variable set the number of ''accepted'' consecutive beacon lost
