while experimenting with an idw01m1 module, I am experiencing deauthentication with the message:
WIND:40:WiFi Deauthentication 3
With the "2015" firmware, the module was unable to reconnect until WiFi was turned off and on.
With latest (2016) firmware the situation has improved a bit, and the module automatically reconnects.
I strongly suspect this behaviour has something to do with a timeout because:
1) it happens only if there is no data exchange
2) it happens exactly and systematically after 300 seconds from the last RX/TX.
Yet, I wasn't able to find a parameter either in the module or in the router to change it.
To connect, I execute this sequence after a factory reset:
Commands are written via console, so I am sure to wait for the correct answer.
With the automatic reconnection, the situation is not that bad. I just fear that DHCP can assign a different IP when the module re-authenticates. This would cause undesired behaviour in my application.
I am using a WPA2 personal authentication. The router is an ASUS N55U.
