Hi
The conditions are as follows:
1. BME688 uses parallel mode
2. Set 10 points, which are consistent with example (parallel_mode.c):
/* Heater temperature in degree Celsius */
uint16_t temp_prof[10] = { 320, 100, 100, 100, 200, 200, 200, 320, 320, 320 };
/* Multiplier to the shared heater duration */
uint16_t mul_prof[10] = { 5, 2, 10, 30, 5, 5, 5, 5, 5, 5 };
3. Continuous sampling multiple times, no sleep
Problems
1) When the heating temperature is 100 ℃, the resistance value will reach the peak of 102400000 ohms (gas_range and gas_res_adc are both 0)
2) After testing for about a month, the sensor has no reaction to some gases
wonder:
1) Is it caused by no sleep in each test?
2) Does not sleep affect sensor life?
3) What conditions will affect the life of the sensor: for example, the selection of parallel mode or force mode, the selection of heating temperature, gas concentration, or the above mentioned sleep?
Thank you for your answer
