Problems running softAP -SDK 1.4.0 [SOLVED]

[PeteW]

Hello all,

I have problems when configuring ESP8266 as AP - I used code from the demo http://bbs.espressif.com/viewtopic.php?f=31&t=227 with small modifications:

1. I set mode to softAP only

   Code: Select all

   wifi_set_opmode(SOFTAP_MODE);
2. Instead of loading previous configuration with wifi_softap_get_config(&config); I set all parameters manually
   

   Code: Select all

   user_set_softap_config(void) {
   struct softap_config config;
   
   os_memset(config.ssid, 0, 32);
   os_memset(config.password, 0, 64);
   
   os_memcpy(config.ssid, "ESP8266", 7);
   os_memcpy(config.password, "12345678", 8);
   config.ssid_len = 0;
   config.channel = 1;
   config.authmode = AUTH_WPA2_PSK;
   config.ssid_hidden = 0;
   config.max_connection = 4;
   config.beacon_interval = 100;
   
   wifi_softap_set_config(&config);// Set ESP8266 softap config
}


If I set channel to 11 where our AP is running everything working fine.
If I set channel to any other from 1 to 13 I can not connect to ESP8266 AP and I am getting following messages on UART:

Code: Select all

chg_A3:-180
chg_A3:0
chg_A3:-180
chg_A3:0
.... and so on


I'm not sure if the problem is after upgrading to SDK 1.4.0 because till now I've worked in mixed softAP+station and when station is activated it forces softAP channel to our AP channel and then everything working as expected.

Any help will be appreciated!

Update: I did same test with SDK 1.3.0 and everything works fine. The problem is definitely SDK 1.4.0 related

Hi,

I tried your test code, our mobile phone and PC can connect to ESP8266 softAP successfully..

Can you provide your test bin ?

I will download it and have a try.

[PeteW]

Here is complete source I used to test and reproduce the problem. In folder bin/upgrade are binaries I'm using. They are complied using following command:

Code: Select all

make clean
make COMPILE=gcc SPI_SIZE_MAP=3 BOOT=new APP=1
make clean
make COMPILE=gcc SPI_SIZE_MAP=3 BOOT=new APP=2


Resulting firmware is flashed using:

Code: Select all

esptool/esptool.py --baud 576000 write_flash 0x00000 bin/boot_v1.2.bin 0x01000 bin/upgrade/user1.2048.new.3.bin 0x81000 bin/upgrade/user2.2048.new.3.bin 0x1FC000 bin/esp_init_data_default.bin 0x1FE000 bin/blank.bin --flash_size 16m


In UART console I'm seeing following:

Code: Select all

mode : softAP(1a:fe:34:9c:61:de)
add if1
dhcp server start:(ip:192.168.4.1,mask:255.255.255.0,gw:192.168.4.1)
bcn 100

INIT: Done

chg_A3:-180
chg_A3:0
add 1
aid 1
station: 0c:84:dc:8d:4c:ad join, AID = 1
chg_A3:-180
chg_A3:0
chg_A3:-180
chg_A3:0
chg_A3:-180
chg_A3:0

chg_A3:0
chg_A3:-180
chg_A3:0
chg_A3:-180
chg_A3:0
chg_A3:-180


The laptop I'm using is running Win 8.1 and connection is briefly established but immediately disconnected. I did not have time to type ping command

Hope this info will help to reproduce the problem at your site.

By the way what is the meaning of chg_A3 message?

[PeteW]

Forgot to remind to set channel (in my case 1) to free one (not used by other AP) before running the example!

Hi,

We optimized our softAP, please have a try with the attachment.

Thanks for your interest in ESP8266 !

[PeteW]

It is working fine! No more chg_A3 messages appeared in the UART console.

Thank you!
