Hi,

I'm interfacing CH101 sensor with Arduino Mega 2560. I'm getting the same log connecting MCU without and with the sensor. Attaching the connections for your reference. I have tested the i2c_scan from MCU. It is detecting addresses as 0x29 0x45.

Does this sensor come with the default firmware? I'm guessing that it is running in free mode. I read the PROG GPIO using digitalRead, It is High.
I have changed resistors on both PROG & RSTN pins with the value of 10KR on 1v8 (sensor side). Still, it didn't work.
