Hi Is the same fix applicable for RTOS 1.4.0 . I face similar issue where station does not get IP when ESP is in AP mode. Also socket open fails.

Hi , I also have same problem, i download the new"esp_iot_sdk_v1.4.1_pre5_15_10_27" SDK ,but the problem is still on, i can't find any AP .How to fixt it?
This is the source code :

void user_init(void)
{

UART_SetBaudrate(UART0,115200); //只能使用本函数设置

wifi_set_opmode(SOFTAP_MODE);
struct softap_config config;
wifi_softap_get_config(&config); // Get soft-AP config first.
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.authmode = AUTH_WPA2_PSK;
config.ssid_len = 0; // or its actual SSID length
config.ssid_hidden = 0;
config.max_connection = 4;
config.channel = 1;
config.beacon_interval=100;
wifi_softap_set_config(&config); // Set ESP8266 soft-AP config
os_free(&config);
}

This is download setting: bank.bin---> 0x7e000 bank.bin--> 0x3fe000 esp_init_data_default.bin--> 0x3fc000 eagle.flash.bin-->0x00000 eagle.irom0text.bin-->0x40000

Hi,

I also use SDK 1.4.0 and have the same UART message as below.

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

Could anyone know how to fix it ?

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

Thank you!

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

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:

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:

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:

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
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.

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.

Problems running softAP -SDK 1.4.0 [SOLVED]

2015-10-22T14:54:55+08:00

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:

I set mode to softAP only
Code:
wifi_set_opmode(SOFTAP_MODE);
Instead of loading previous configuration with wifi_softap_get_config(&config); I set all parameters manually
Code:
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:

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!
