[Resolved]ESP8266 only concts to ESP8266 in softAP w OPEN encryption

[mvandere]

Hi There seems to be some discussion in this area although it doesn’t always seem relevant. I’m trying to connect 2 ESP8266s with one in softAP mode. The connection fails unless OPEN encryption is used and I can’t figure out why. I’ve tried longer AP names as suggested in some posts but this seems to make no difference.
I’m using the latest AT commands AT_v0.25
Here’s the AP setup log

Code: Select all

AT+CWMODE_CUR=2


OK
AT+CWSAP_CUR="ESP826612345678","1234567890",5,3


OK

Here’s the attempt to connect

Code: Select all

AT+CWJAP_CUR="ESP826612345678","1234567890"

WIFI CONNECTED
+CWJAP:1

FAIL
WIFI DISCONNECT


Can anyone tell me how to get it to work.
Thanks,
Mark

Hi,

Thanks for your interest in ESP8266 !

What's the version of your hardware module ? Is it ESP-01 ?

Could you offer the capture picture of your flash download tool while downloading AT firmware into flash ?

[mvandere]

They are ESP-12s

Here's the log from your ESP FLASH DOWNLOAD tool

Hi,

Sorry that I can't duplicate your problem.

Please notice that if you are using 32Mbit flash , blank.bin need to be downloaded to both 0x7E000 and 0x3FE000

[mvandere]

Could you provide a command log from both sides that works, so that I can use that and try and work out the difference between my failing commands and yours that work?

Hi,

Here is my test steps and flash download tool configuration

STA_AP_test.png (50.85 KiB) Viewed 13127 times

Serial-COM6 is the ESP8266 as softAP, Serial-COM7 is another ESP8266 as station

I'm using the AT bin (\esp_iot_sdk_v1.1.1\bin\at) http://bbs.espressif.com/viewtopic.php?f=5&t=554

[mvandere]

I started with what you have shown and was still getting the "FAIL". Due to the 'WIFI GOT IP' message that is received when everything is working I was playing around with DHCP settings and the like and 'suddenly' it came good. Here's a log of it not working and then working (Remember there are other 'changes' that have happened, this is just the last one)

I think tried various things and it worked every time. I even reflashed it and it still works using the exact commands that previously failed.

The "SPI Flash Size & Map: 32Mbit(512KB+512KB)" message that comes up during boot, is that actual, or from a setting somewhere?

How can I completely clear the flash to ensure that I am starting with a 'clean slate'?

Thanks.

Hi，

blank.bin is downloaded for initialization，please download blank.bin into flash according to documentation “4A-ESP8266__AT Instruction Set”

[elchupacabra]

yes... got the same disconnecting errors. Problem solved by flashing the blank.bin to both 0x7E000 and 0x3FE000 !!. Now works OK!
