questions regarding NRF_SDH_BLE_OBSERVER in SDK14

[arai]

I am trying to port my code form SDK 12.1 to SDK14. I am using NRF52832
I have gone through the example code and trying to initialize a ble event in ble_stack_init() using the following code

NRF_SDH_BLE_OBSERVER(m_rt_observer, APP_BLE_OBSERVER_PRIO,ble_r_tuning_on_ble_evt,(void*)&m_r_tuning);

1. I am getting the following error:

error: initialization from incompatible pointer type [-Werror]
NRF_SDH_BLE_OBSERVER(m_rt_observer, APP_BLE_OBSERVER_PRIO,ble_r_tuning_on_ble_evt,(void*)&m_r_tuning);
^
../../../main.c:2926:2: error: (near initialization for 'm_rt_observer.handler') [-Werror]

What is causing this?

2. Also would like to know if I can use NRF_SDH_BLE_OBSERVER to initialize two different ble events.

Thank you,

Ashish

Hi,

Have you included the *observers* sections in your linker script?  You may use the linker scripts from SDK 14 as reference. With regards to the build error, I guess the problem may be related to the ble_r_tuning_on_ble_evt() definition. Please check if it has the correct input list: ble_r_tuning_on_ble_evt (ble_evt_t const * p_ble_evt, void * p_context)

You can register multiple BLE observers. More on the new softdevice handler here: http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/lib_softdevice_handler.html?cp=4_0_0_3_44
