I'm new on ESP8622. I'm currently trying to setup the device on SOFTAP mode to connect my computer but the station keeps disconnecting immediately after connection. It does not seems to reboot though.

On the AP side (ESP8266):

Code: Select allAT+GMR
AT version:0.40.0.0(Aug  8 2015 14:45:58)
SDK version:1.3.0
Ai-Thinker Technology Co.,Ltd.
Build:1.3.0.2 Sep 11 2015 11:48:04
OK


On the station side (computer):
I'm running Linux Mint 18 with a 4.4 kernel.

Here is the output of dmesg:

Thanks by advance

- Mon Dec 05, 2016 1:43 am #59113 Seems that getting the latest ESP8266 SDK fixed the problem.

- Mon Dec 05, 2016 6:08 am #59122 make sure your module in AT+CWMODE=x
x = 1 OR 3 >> static | both
