SDK15 HID service_error_handler NRF_ERROR_NO_MEM

[Hung Alan]

I am working in sdk15 nrf52832 ble_app_hids_keyboard.

I want merge ble_app_uart_c ,so modify in 

sdk_config.h :

NRF_SDH_BLE_CENTRAL_LINK_COUNT 1

PM_CENTRAL_ENABLED 1

But bonding with Iphone

Debug massege :

16:12:49.746> <error> app: ERROR 4 [NRF_ERROR_NO_MEM] at ..\..\..\main.c:502
16:12:49.746> PC at: 0x00034503

static void service_error_handler(uint32_t nrf_error)
{
APP_ERROR_HANDLER(nrf_error);
}

nrf_error is 0x00000004(NRF_ERROR_NO_MEM)

I don't know where no memery .

Hi!

Hard to say what is returning the error, as I don't know what your modified code looks like.

However, when you are migrating the ble_app_uart_c to the ble_app_hids_keyboard example, you are most likely adding a vendor specific UUID.

When doing this, you should specify the number of vendor-specific UUIDs in the sdk_config.h file.

Maybe you start by taking a look at the #define NRF_SDH_BLE_VS_UUID_COUNT
and see that it is set to 1 and not 0?

If that isn't helpful, please let me know so we can look closer at the problem.

Best regards,
Joakim.

I am working now.

I modify in 

#define  NRF_SDH_BLE_CENTRAL_LINK_COUNT 1

#define  PM_CENTRAL_ENABLED 1

#define NRF_SDH_BLE_TOTAL_LINK_COUNT 2 

thanks
