LAUNCHCC3220MODASF: get provisioning status at power up?

Part Number: LAUNCHCC3220MODASF

I've noticed that if the provisioning process is interrupted, sl_FsOpen(), eg, will fail with -2014 (PROVISIONING_IN_PROCESS) at power up.  A reset doesn't fix it, so my guess is that there's a flag set in flash ROM for this.  What I'd like to do is check for this and clear it if possible.

Right now, I guess I could test for -2014 error returned from sd_FsOpen(), then try to issue 

 sl_WlanProvisioning(SL_WLAN_PROVISIONING_CMD_STOP,0xFF,0,NULL, 0x0);

  to (hopefully) clear the flag. 

Is this the right approach?

Thanks!

Chris

    Hi Chris,

    The approach you have is correct. If you look at the out_of_box example, it has the same idea in provisioningStop() of provisioning_task.c. In that function, it calls a simple API to get the NWP firmware version numbers, but is really there to check for that -2014 PROVISIONING_IN_PROCESS error and then turn off provisioning if that is the case:

    SlDeviceVersion_t ver = {0};
    uint8_t configOpt = 0;
    uint16_t configLen = 0;

    /* check if provisioning is running */
    configOpt = SL_DEVICE_GENERAL_VERSION;
    configLen = sizeof(ver);
    retVal =
        sl_DeviceGet(SL_DEVICE_GENERAL, &configOpt, &configLen,
                     (uint8_t *)(&ver));
    if(SL_RET_CODE_PROVISIONING_IN_PROGRESS == retVal)
    {
        UART_PRINT(
            "[Provisioning task]  Provisioning is already running, "
            "stopping it...\r\n");
        retVal =
            sl_WlanProvisioning(SL_WLAN_PROVISIONING_CMD_STOP,ROLE_STA,0,NULL,
                                0);

        /* wait for the stopped event to arrive - wait for PrvnState_Init */
        do
        {
            provisioningState = GetProvisioningState();
            usleep(1000);
        }
        while(provisioningState != PrvnState_Init);

        pCtx->provisioningStatus = PrvsnStatus_Stopped;

        retVal = SL_RET_CODE_PROVISIONING_IN_PROGRESS;
    }

    Let me know if you need more clarification or have further questions on this topic.

    Regards,
    Michael
