Switching issue for config mode in Beacon.

[GeekGeek1192]

Hello,

          I am new to BLE. I am currently working on a beacon application. I have used the beacon example code from SDK and modified it. I am using SDK-17.1.0 controller is nrf52832 with softdevice 132. My Beacon mode is working fine. Now I am using button interrupt to put my device into config mode. But as soon as I enter into the advertising init function My device gets restarted. When debugged found that it was showing error code 4. I have gone through one of the post but could not able to solve the error. In my beacon mode, I am directly transmitting my raw data over BLE.

 kindly suggest what to do for switching into config mode.... I haven't added any services yet but in future will be added.

Thank You

Hello Vidar,

                  If I start debugging in debug configuration, the project does not get started... It gives errors but the code is working in release configuration. I don't know-how.

[Vidar Berg]

Hello,

Please post a screenshot of the errors you get.

[GeekGeek1192]

Hello Vidar,

                   I tried with the same handle for advertising, still, my controller gets reset in the advertising_init() function. I have pasted the below image from debugging configuration. Please suggest me what to do next?

 

[Vidar Berg]

Hello,

The first sceenshot shows that the error is coming from the call to sd_ble_gap_adv_set_configure(), which indicates that it is trying to allocate a new advertising handle.

Can you place the breakpoint and read the adv. handle value as shown below?

[GeekGeek1192]

[Vidar Berg]

.adv_handle is only supposed to be '0xff' the first time you call ble_advertising_init(). It must be '0' on subsequent calls.

[GeekGeek1192]

What is missing from my procedure? how to resolve this issue then?

[Vidar Berg]

Can you please upload your updated code so I can take a look?

Can you verify that 'm_adv_handle' is '0' before you call ble_advertising_init() in advertising_init(). I don't see where m_adv_handle is defined in the code you posted.

Below snap is before starting the debug.

Below image is after calling bc_advertising_init()

Befor ble_advertising_init() function

after  ble_advertising_init() calling

Should I make m_adv_handle  zero.

m_adv_handle=0; like this?

Thanks. So after a closer look at you code I notice you are not using ble_advertising_init() in BC_advertising_init(). This means the advertising module is not initialized until you call advertising_init(), and this will cause your adv. handle to be set back to 0xFF here:

A hack to get around this is to set the .initialized flag to 'true' before calling ble_advertising_init() in advertising_init():

static void advertising_init(void)
{
    ...
    m_advertising.adv_handle = m_adv_handle;
    m_advertising.initialized = true;

    err_code = ble_advertising_init(&m_advertising, &init);
    APP_ERROR_CHECK(err_code);
    ...
