    snip.scan cannot see access points on channel 13

      I'm using WICED/WICED-SDK-MFi-3.1.0/apps/snip/scan/ application on Inventek Systems ISM43362-M3G-L44-E

      it runs fine and successfully discovers access points on channels lower than (including) 11,

      but doesn't see access points on channel 13.

       

      I understand it's not permitted in FCC area to use channel 13,

      so I assumed I needed to change country_code and added:

       

      #define WICED_COUNTRY_CODE  WICED_COUNTRY_JAPAN
      

       

      in WICED-SDK-MFi-3.1.0/include/default_wifi_config_dct.h

       

      but this doesn't change anything.

      What should I change to see access points on channel 13?

       

      Thanks in advance.

          Hello,

          I can run scan command in console, and it works fine.

          10:50:23.086:  20 Infra 94:39:E5:53:1E:CD  -62 144.4   13  Open        GangiCH13

          I modified the \apps\test\console\wifi_config_dct.h

           

          And type scan at the prompt:

          It found my AP on channel 13.

          I will check how to change the default CC that the scan command uses.

            I have the "scan" snip seeing my Ch13.

            Here is what I did:

             

            Modify scan.mk file to not use the default wifi_config_dct.h as follows:

            #

            # Copyright 2014, Broadcom Corporation

            # All Rights Reserved.

            # or duplicated in any form, in whole or in part, without the prior

            #

             

             

            NAME := App_Scan

             

             

            $(NAME)_SOURCES := scan.c

            WIFI_CONFIG_DCT_H := wifi_config_dct.h

             

             

            Next:

            I added a wifi_config_dct.h to the snip.scan folder, you can copy and paste it from the test.console folder.

            and change the #define WICED_COUNTRY_CODE    WICED_COUNTRY_JAPAN as you did.

              Thanks gangi for your response.

              I followed your guidance and successfully found APs with channel 13.

                Dear gangi

                 

                  I also have spent time a lot for this issues because I have used "default_wifi_config_dct.h"

                  and changed  country domain code as below

                 

                //#define WICED_COUNTRY_CODE    WICED_COUNTRY_UNITED_STATES

                #define WICED_COUNTRY_CODE    WICED_COUNTRY_KOREA_REPUBLIC_OF

                 

                By testing with you information,  by changing WICED_COUNTRY_CODE in "default_wifi_config_dct.h" file

                but by adding "wifi_config_dct.h"  in make file and adding   "#define WICED_COUNTRY_CODE    WICED_COUNTRY_KOREA_REPUBLIC_OF" is working.

                 

                This kinds of information should be written to application notes or bug reports.

                or it should be patched.

                 

                I think that most of users who have different country domain may face this issue and spend time.

                 

                TKS
