Hello,
I'll explain my code:
NRF51 takes samples of a sensor every 10 minutes. In addition, softdevice S110 is used... An user can connect at any time, so advertising is used all the time.
When I leave the device for hours, i can't connect to device, an error occurs and NRF51 is reset.
Any help?
My configuration:
#define APP_ADV_INTERVAL 180
#define APP_ADV_TIMEOUT_IN_SECONDS 0
#define APP_TIMER_PRESCALER 0
#define APP_TIMER_MAX_TIMERS (16 + BSP_APP_TIMERS_NUMBER)
#define APP_TIMER_OP_QUEUE_SIZE 8
#define MIN_CONN_INTERVAL MSEC_TO_UNITS(20, UNIT_1_25_MS)
#define MAX_CONN_INTERVAL MSEC_TO_UNITS(75, UNIT_1_25_MS)
#define SLAVE_LATENCY 0
#define CONN_SUP_TIMEOUT MSEC_TO_UNITS(6000, UNIT_10_MS)
#define FIRST_CONN_PARAMS_UPDATE_DELAY APP_TIMER_TICKS(5000, APP_TIMER_PRESCALER)
#define NEXT_CONN_PARAMS_UPDATE_DELAY APP_TIMER_TICKS(30000, APP_TIMER_PRESCALER)
#define MAX_CONN_PARAMS_UPDATE_COUNT 3
And mi advertising_init function:
static void advertising_init(void){
uint32_t err_code;
ble_advdata_t advdata;
ble_advdata_t scanrsp;
// Build advertising data struct to pass into @ref ble_advertising_init.
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance = false;
advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
memset(&scanrsp, 0, sizeof(scanrsp));
scanrsp.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
scanrsp.uuids_complete.p_uuids = m_adv_uuids;
ble_adv_modes_config_t options = {0};
options.ble_adv_fast_enabled = BLE_ADV_FAST_ENABLED;
options.ble_adv_fast_interval = APP_ADV_INTERVAL;
options.ble_adv_fast_timeout = APP_ADV_TIMEOUT_IN_SECONDS;
err_code = ble_advertising_init(&advdata, &scanrsp, &options, NULL, NULL);
APP_ERROR_CHECK(err_code);
}
Thanks in advance.
