- Tue Feb 24, 2015 12:27 am #10583 To fix your issue here, use the right SDK :

In esphttpd source :

make SDK_BASE=/opt/Espressif/esp-open-sdk/sdk

- Wed Feb 25, 2015 3:44 am #10673 esphttpd compiling, linking, working: It's all perfect when working in STATION_MODE and having defined WIFI_CLIENTSSID and WIFI_CLIENTPASSWORD in user_config.h.
But I don't want to ship out the ESP with my WLAN parameters.
So I tried the original

Code: Select all#define USE_WIFI_MODE      STATIONAP_MODE
#define WIFI_CLIENTSSID      "MYAP"
#define WIFI_CLIENTPASSWORD   "00000000"
#define WIFI_AP_NAME      "ESP8266"
#define WIFI_AP_PASSWORD   "00000000"
#define PLATFORM_DEBUG      true


In this case ESP goes in AP-mode, I can connect to ESP8266 and I can call 'do so' .
But now the show stopper: There is displayed 'Scanning...'
but serial output shows nothing about scanning AP's and display remains in Scanning....

Btw in the working case(see on top) I also can 'do so' and then the scanning of AP's is done and connection to other AP is possible.

What's the difference?????

- Wed Feb 25, 2015 6:26 am #10683 I've connected to other access point through wifi settings in STA+AP mode. I can ping ESP by new IP from that access point, but web server not responding. Can anybody help me?

- Wed Feb 25, 2015 2:52 pm #10717 I'm trying to resolve the same error in SDK 0.9.5 but I just can't find what the issue is. I can use os_printf and os_printf_plus in other programs, but I just can't track down what's going here!

Did you manage to resolve it?
------------------------------------

Ok I think I narrowed it down a little more.

I should have mentioned I am using SDK 0.9.5 not sure if thats the cause. But I discovered that the c_types.h in the SDK has the typedef for uint32_t commented out and seems to be relying on including the default C stdint.h. However this doesnt work as a dummy stdint.h is included in the esp-httpd includes folder.

I noticed the SDK have a c_types.h.orig file which has the commenting removed. If I use this file I now get a little further. But get a new error.

Code: Select allCC user/httpd.c
user/httpd.c: In function 'httpdFindConnData':
user/httpd.c:97:2: error: implicit declaration of function 'os_printf_plus' [-Werror=implicit-function-declaration]
  os_printf("FindConnData: Huh? Couldn't find connection for %p\n", arg);

I am not sure if this is simply because the code base doesn't work against the 0.9.5 SDK or some environment problem on my end.
