Hello, Recently, I was testing the BME688 sensor in an application where it detects substances in water. But, when testing, the sensor might have touched the surface of the water. I  am not completely sure though, because I was not able to exactly see it. Some of the problems that I have started noticing are that the board is having trouble connecting to the android app. The red and yellow light are both turning on at the normal intervals, but the bluetooth capability doesn't seem to be working. Does water damage the BME688 board (paired with Adafruit Huzzah esp32 Feather)? Furthermore, are there any solutions to fixing a water damaged board? Thank you the help. @Minhwan @BSTRobin  ...

I am using the BME688 sensor in combination with the Adafruit Huzzah ESP32 in order to detect the gas composition. I am also using the software of the BME Dev Kit and Bosch AI Studio. I tested out the technology on coffee, and got a good detection rate of 98%. But, when I did the same for peanuts (roasted, raw, hot, and cold), it only got 75% and was often being confused for just normal air. What are some ways tweak the sensor parameters or sensitivity to make them more aligned with detecting  these less evident smells? Please advise on how to change the sensor parameters, or the number of sensors that are being  used, so that I can optimize the detection capabilities for my application. Thank you for your help. ...
