Hi,

It is designed like this.

If you need the current parameters of the connected AP, please use command "AT+CWJAP_CUR?"

Thanks for your interest in ESP8266 !

Thank you for your answer.
It seems a little bit weird for me to not show the connected AP's bssid but show a flash stored bssid instead.
What if these two are different?
Let's try to give a fake bssid:

Code:

AT+CWJAP_DEF="Pelican Network","xxxxxxxx","11:22:33:44:55:66"
WIFI CONNECTED
+CWJAP:1

FAIL
WIFI DISCONNECT
AT+CWJAP_DEF="Pelican Network","xxxxxxxx"
WIFI CONNECTED
WIFI GOT IP

OK
AT+CWJAP_DEF?
+CWJAP_DEF:"Pelican Network","11:22:33:44:55:66",1,-76

OK
AT+CWJAP?
+CWJAP:"Pelican Network","44:32:c8:fe:10:b2",1,-75

OK
AT+CWJAP_CUR?
+CWJAP_CUR:"Pelican Network","44:32:c8:fe:10:b2",1,-78

OK

And now it shows the fake bssid instead of the real one.
Storing the bssid makes no sense because it's only necessary to find the right AP if more than one share the same ssid.
When I use the AT+CWJAP_DEF? command I want to see the current parameters of the connected AP.
It's a bug, isn't it?

Hi,

So sorry that I made a mistake.

After consulting our engineer, the MAC address (bssid) of AT+CWJAP_DEF needs to be set by the command AT+CWJAP_DEF=,,.

AT+CWJAP_DEF=,, will set the configuration into Flash.
And command AT+CWJAP_DEF? will read the configuration from Flash.

AT+CWJAP_CUR=, will not set the configuration into Flash.
And the command AT+CWJAP_CUR? will get the bssid of current connected AP.

Hi,

Please notice that to use "AT+CWJAP_DEF?" you need to use AT+CWJAP_DEF="SSID", "password", use the matching command.

I've put the blank.bin but everything is the same.

Hi,

The blank.bin needs to be downloaded to both 0x7e000 and 0xfe000 to run the AT firmware.

You can download the AT bin files into Flash, according to the bin\at\readme.

If your problem is still unsolved, please feel free to let us know.

Thanks for your interest in ESP8266 !

I tried to do everything according to the manual.
I've used the FLASH_DOWNLOAD_TOOLS_v2.4_150924 software but it says its v2.3.

Hi,

It seems that you did not download blank.bin into flash as the initialization.

Please use ESP Flash Download Tool to download the bin files into Flash, according to the at\readme.

If your problem is still unsolved, please provide the captured picture of ESP Flash Download Tool while downloading for debugging.

Thanks for your interest in ESP8266 !

AT+CWJAP_DEF issue

2016-04-19T18:55:17+08:00

I'm new here and I don't know if there is any forum where I can report bugs/issues so I write it here.
The AT+CWJAP_DEF? cannot give back the correct mac address. Not a big deal but maybe somebody knows how to fix it.

Code:

AT+GMR
AT version:1.0.0.0(Apr 16 2016 13:02:45)
SDK version:1.5.3(aec24ac9)
compile time:Apr 18 2016 14:20:15
OK
AT+CWMODE=1

OK
AT+CWJAP?
+CWJAP:"Pelican Network","44:32:c8:fe:10:b2",1,-76

OK
AT+CWJAP_DEF?
+CWJAP_DEF:"Pelican Network","ff:ff:ff:ff:ff:ff",1,-82

OK
AT+CWJAP_CUR?
+CWJAP_CUR:"Pelican Network","44:32:c8:fe:10:b2",1,-81

OK
