Unexpected error code after AT+CWJAP_CUR with an incorrect password.

[yamazaki]

Hi,

Currently I’m testing with NONOS_SDK_V2.0.0 (including patch).
However one difference is observed between 1.5.1 and 2.0.0 as following.

I sent AT+CWJAP_CUR with a correct SID and an incorrect password, but replied error code from esp8266 is “1: connection timeout”.

AT+CWJAP_CUR="APxxx","pass1234"
WIFI DISCONNECT
+CWJAP:1

FAIL

In the same test case with 1.5.1, esp8266 replies Error code “2: wrong password” expectedly.

AT+CWJAP_CUR=" APxxx "," passw1234"
WIFI DISCONNECT
+CWJAP:2

FAIL

Could someone tell me why the difference is observed and also tell me how to avoid the issue?

Thanks in advance for your help!

Hi:
Before you conifg wifi(AT+CWJAP),you can user AT+CWMODE=1 or AT+CWMODE=3.Module wifi mode is station.

Hi Xutao-san,

Thank you for the comment.
But I always send "AT+CWMODE=1" before "AT+CWJAP_CUR" as you described.
