Hi! I have asked a question in this topic (devzone.nordicsemi.com/.../) and now I can send one packet of 20bytes. What I cannot do is sending two packets at the same time, because what I see is that my beacon sends two packets separately. My application uses the ADC every 2ms, I put the result of the conversion in an array and when I reach 20bytes I send it, so this takes 20ms(I use the 10bit conversion). When I add the second packet I expect to see the two packets at the same time every 40ms, instead I see one packet every 20ms. This is part of my code:
void ADC_IRQHandler(void)
{
/* Clear dataready event */
NRF_ADC->EVENTS_END = 0;
/* Write ADC result to port 2 */
//nrf_gpio_port_write(NRF_GPIO_PORT_SELECT_PORT2, NRF_ADC->RESULT);
//Invio a pacchetti di 20 bytes (ogni dato in uscita dall'adc è 1byte)
static uint8_t i=0; //usiamo static per evitare che modifichi il valore della variabile
static uint8_t j=0;
static uint16_t adc_results[10]; //adc a 10bit, salviamo il risultato su 16bit per non sprecare spazio nel pacchetto
static uint16_t adc_results_2[10];
if (i<10)
{
adc_results[i]=1;//NRF_ADC->RESULT;
i++;
}
if ((i >= 10) & (i<20))
{
adc_results_2[j]=2;//NRF_ADC->RESULT;
i++;
j++;
}
if (i==20)
{
our_termperature_characteristic_update(&m_our_service, adc_results, adc_results_2); //una volta riempito il pacchetto lo invia
for(i=0;i<10;i++)
{
adc_results[i]=0; //azzera il pacchetto
adc_results_2[i]=0;
}
i=0; //azzera l'indice
j=0;
}
//Use the STOP task to save current. Workaround for PAN_028 rev1.5 anomaly 1.
NRF_ADC->TASKS_STOP = 1;
//Release the external crystal
sd_clock_hfclk_release();
}
void our_termperature_characteristic_update(ble_os_t *p_our_service, uint16_t temperature_value[], uint16_t temperature_value_2[])
{
// OUR_JOB: Step 3.E, Update characteristic value
if (p_our_service->conn_handle != BLE_CONN_HANDLE_INVALID)
{
uint16_t len = 20; //modificato per ricevere tutti i dati del pacchetto
ble_gatts_hvx_params_t hvx_params;
memset(&hvx_params, 0, sizeof(hvx_params));
hvx_params.handle = p_our_service->char_handles.value_handle;
hvx_params.type = BLE_GATT_HVX_NOTIFICATION;
hvx_params.offset = 0;
hvx_params.p_len = &len;
hvx_params.p_data = (uint8_t*)temperature_value;
sd_ble_gatts_hvx(p_our_service->conn_handle, &hvx_params);
hvx_params.p_data = (uint8_t*)temperature_value_2;
sd_ble_gatts_hvx(p_our_service->conn_handle, &hvx_params);
}
