CC3235SF: config only conect 5g but can connect 2.4G

Part Number: CC3235SF

Tool/software:

Hi TI engineer

       I had build two firmware. one firmware is V1.0.1 ，can connect 2.4G/5G WIFI. Another is V1.0.2  ，only connect 5G WIFI（set 2.4G channel mask 0x0000）。

      I have a AP broadcast 2.4G/5G, the V1.0.1 can connect this AP by 2.4G/5G.   And V1.0.2 only connect 5G wifi.

     When V1.0.1 connect AP by 2.4g,and then OTA firmware to V1.0.2. After OTA success(CC3235 wifi config same),CC3235 still connect AP by 2.4G and not 5G wifi. Then Config dev to connect another 2.4g AP , dev can't connect.  config dev connect another 5G AP,dev connected. So i think CC3235 store connected wifi info,and use this wifi info to connect .

     Is my think correct?  If yes, how do I delete the connected wifi information?

    Hi,

    Not very clear. Are you saying that v1.0.2 worked OK and connected to 5G only and after OTA it also connected to 2.4G? please clarify.

    in general, if you have auto connect and fast connect enabled, the profiles are stored in the file system and used. To delete the profiles, you need to use the sl_WlanProfileDel() API.

    Hi

        Thanks reply.

         If  flash firmware to V1.0.2,the CC3235 only connected 5G WIFI. Flash firmware to V1.0.1 and connected 2.4G wifi ,if OTA(OTA not modify the dev config) to V1.0.2 the CC3235  still connected to this 2.4Gwifi .

       My code will del the profile。

    What does this OTA contains?

    OTA only update firmware from V1.0.1 to V1.0.2. Compared to v1.0.1, V1.0.2 only sets the 2.4G channel to 0X0000.   CC3235 will load wifi config file  when boot ,nd the config not modify when ota. After OTA to V1.0.2,the CC3235 will connect to the AP configured from V1.0.1 firmware.  But CC3235 connected a 2.4GWIFI not 5G wifi

    HI,

    It is the "chicken and the egg" since v1.0.1 stores the 2.4 profile and during the OTA procedure this profile is not deleted. After the OTA to v1.0.2 is completed, the sl_Start() API is called and before the profiles are deleted, the 2.4 profile is invoked and connected. This is why you are not able to connect to a new 2.4 AP.

    According to this theory, after the profiles are deleted and you disconnect from the AP (via sl_wlanDisconnect()), reloading the application should not allow you to connect.
