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 that arise: Query gas_index, you will find that occasionally there are several temperature points in the process that do not produce valid data. For example: gas_index 0~9 can query new valid data in most cases. But in a few cases, for example, when gas_index = 3, there is no data, and finally only data with gas_index of 0, 1, 2, 4, 5, 6, 7, 8, and 9 can be obtained. Is this normal? If it's not normal, how can I use it correctly? Looking forward to your answer, thank you!
