idw01m1 deauthenticated

Hello folks,

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:

at+s.scfg=wifi_wpa_psk_text,<password>

at+s.ssidtxt=<my SSID>

at+s.scfg=wifi_priv_mode,2

at+s.scfg=ip_use_dhcp,1

at+s.scfg=wifi_mode,1

at+s,wifi=0

at+s.wifi=1

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.

Hints?
