Hello I am working on BME680 sensor  for my enviromental project, As per suggestion I am using BSEC Library, I have intedgrated with my MCU and it works fine , while reading continuously , This was my fist phase of the project which is completed, But now I want to my MCU to be in low power mode , My MCU will goes into sleep mode for 5 mins and wake up collect data from the BME680 and then goes to sleep. But the provlem occurs here , when the MCU runs in continous mode IAQ accuracy works fine ( 0 , 1 ,2 and 3) , Like for example  when the IAQ accuracy is set to 1 or 2 , and then I active the sleep mode , after five minutes when the MCU wakes up , I notice that IAQ accuracy is reset to zero (0). I am working from last one week yet the problem still exists.  Any help regarding this will much be appreciated. Thanks This is the initialization IoT endless loop while (1) { if ( onoffflag == 1 ) { /* get the timestamp in nanoseconds before calling bsec_sensor_control() */ time_stamp = get_timestamp_us() * 1000; /* Retrieve sensor settings to be used in this time instant by calling bsec_sensor_control */ bsec_sensor_control(time_stamp, &sensor_settings); /* Trigger a measurement if necessary */ bme680_bsec_trigger_measurement(&sensor_settings, sleep); /* Read data from last measurement */ num_bsec_inputs = 0; bme680_bsec_read_data(time_stamp, bsec_inputs, &num_bsec_inputs, sensor_settings.process_data); /* Time to invoke BSEC to perform the actual processing */ bme680_bsec_process_data(bsec_inputs, num_bsec_inputs, output_ready); /* Increment sample counter */ n_samples++; /* Retrieve and store state if the passed save_intvl */ if (n_samples >= save_intvl) { bsec_status = bsec_get_state(0, bsec_state_loop, sizeof(bsec_state_loop), work_buffer, sizeof(work_buffer), &bsec_state_len_loop); if (bsec_status == BSEC_OK) { state_save(bsec_state_loop, bsec_state_len_loop); } n_samples = 0; } /* Compute how long we can sleep until we need to call bsec_sensor_control() next */ /* Time_stamp is converted from microseconds to nanoseconds first and then the difference to milliseconds */ time_stamp_interval_ms = (sensor_settings.next_call - get_timestamp_us() * 1000) / 1000000; if (time_stamp_interval_ms > 0) { sleep((uint32_t)time_stamp_interval_ms); } } ...
