s130 Cental peripheral error 3002 : NRF_ERROR_SOFTDEVICE_NOT_ENABLED

[Kapil Rawat]

Hi I'm trying to send adc value from peripheral to central. I'm using nrf51822 with softdevice s130_1.0.0 and SDK v10.0.0 .

I'm getting error 3002 which I figured out, it is STK+NRF_ERROR_SOFTDEVICE_NOT_ENABLED. I also call softdevice_handler_isEnabled() function in main which is returning true.

here is my code

uint32_t ble_adc_on_adc_change(ble_adc_t * p_adc, uint16_t adc_state)
{
    ble_gatts_hvx_params_t params;
    uint16_t len = 2;
		uint8_t data[2] 	=	{(uint8_t) (adc_state>>8), (uint8_t) adc_state}; 	
	  
    memset(&params, 0, sizeof(params));
    params.type = BLE_GATT_HVX_NOTIFICATION;
    params.handle = p_adc->adc_char_handle.value_handle;
    params.p_data = data;
    params.p_len = &len;
		
    return  sd_ble_gatts_hvx(p_adc->conn_handle, &params);
}

Can any one please let me know how to correct this.

No it's not STK+NRF_ERROR_SOFTDEVICE_NOT_ENABLED. If you look at the documentation for the function it tells you the return codes it can return and their derivation, and you can click on them to break them down more.

#define BLE_ERROR_INVALID_CONN_HANDLE   (NRF_ERROR_STK_BASE_NUM+0x002)

that's 0x3002

Yes that why I wrote NRF_ERROR_SOFTDEVICE_NOT_ENABLED

here is the nrf_error.h file code

Hi

Error 0x3002 is BLE_ERROR_INVALID_CONN_HANDLE. It is defined in ble_err.h as:

#define BLE_ERROR_INVALID_CONN_HANDLE    (NRF_ERROR_STK_BASE_NUM+0x002) /**< Invalid connection handle. */

where NRF_ERROR_STK_BASE_NUM is defined as 0x3000 in nrf_error.h.

You are probably getting this error because you are calling ble_adc_on_adc_change() and sd_ble_gatts_hvx() without being in a connection. If you look in the SDK examples you will see that we always check for a valid connection before we call sd_ble_gatts_hvx() like this:

if (p_hrs->conn_handle != BLE_CONN_HANDLE_INVALID)
{
    ....
    err_code = sd_ble_gatts_hvx()
    ....
}
