Hello,

Do you have any experience in connecting FireBeetle 2 ESP32-S3(N4) to DFRobot Gravity: Lightning Sensor? Unfortunately, I try various combinations, but the detector does not respond even to interference. I run the code in the Arduino IDE. The code comes as below. I have tried various combinations of SDA, SCL, IRQ, but the detector does not respond. On the board I use the pins described as SDA and SCL. Despite this, it didn't work. Does the DFRobot_AS3935_I2C.h library not work with the microcontroller?

Regards,
