Another pb with Multichannel Gas Sensor

Products & Technology Grove
#1

Hello,



I have an annoying problem with the I2C communication with the Gas Sensor. Sometimes, when the CPU reset (ESP32), I am unable to recover the communication with the sensor. the getVersion() is giving me 1 instead of 2 and all the readings are faulty (-1 in general).



The only solution found is to power off the device by unplugging the red cable.



Any way to reset the device via I2C ?



Thanks
