Hi!
Is there any tutorial or help devoted to sensors of ruuvitag?
I am trying to read sensors in a new project (not a sample but I looked to firmware sample)
I have this code:
β¦
int main(void)
{
uint32_t err_code;
err_code = NRF_LOG_INIT(NULL);APP_ERROR_CHECK(err_code);
APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
err_code = bsp_init(BSP_INIT_LED, APP_TIMER_TICKS(100, APP_TIMER_PRESCALER), NULL);
APP_ERROR_CHECK(err_code);
init_sensors();
ble_stack_init();
//TIMER (now with RTC due to cle_stack_init call)
init_timer(main_timer_id, MAIN_LOOP_INTERVAL_RAW, main_timer_handler);
app_timer_stop(main_timer_id);
//app_timer_start(main_timer_id, APP_TIMER_TICKS(MAIN_LOOP_INTERVAL_RAW, RUUVITAG_APP_TIMER_PRESCALER), NULL); // 1 event / 1000 ms
app_timer_start(main_timer_id, 32768, NULL); // 1 event / 1000 ms
bme280_set_oversampling_hum(BME280_HUMIDITY_OVERSAMPLING);
bme280_set_oversampling_temp(BME280_TEMPERATURE_OVERSAMPLING);
bme280_set_oversampling_press(BME280_PRESSURE_OVERSAMPLING);
bme280_set_iir(BME280_IIR);
bme280_set_interval(BME280_DELAY);
bme280_set_mode(BME280_MODE_NORMAL);
init_watchdog(NULL);
advertising_init();
advertising_start();
// Enter main loop.
for (;; )
{
power_manage();
}
Then, in the main_timer_handler() I call:
bme280_read_measurements();
raw_t = bme280_get_temperature();
raw_p = bme280_get_pressure();
raw_h = bme280_get_humidity();
but program hangs in bme280_read_measurements()
what could be the reason for this?
Note: no debug facility, I am flashing tag using mobile phone.
Thanks a lot
Alex
