Unable to Read Sensor Data via I2C on LilyGO LoRa32 #182

Open Mariiian09 opened 5 days ago

Mariiian09 commented 5 days ago

I am experiencing issues with connecting a sensor to the I2C interface on my LilyGO LoRa32 board. I have connected the sensor (SHT20 humidity and temperature DFRobot) to pins 21 (SDA) and 22 (SCL) but I am not receiving any data from the sensor. The sensor has four pins: VCC, GND, SDA, and SCL.
