I have a sensor that works on two modes (I2C,UART),I am converting the i2c to uart and similarly from uart to i2c. after changing the mode from uart to i2c i am unable to detect the address.I have connected the sensor tx,rx pins to A4,A5 and same to rx and tx(PIN 0, PIN 1).After I change the mode from uart to i2c using nodejs the voltage across the pin 0, pin 1 is 3V. But when the remove the jumper wires from the pin 0 and pin 1 i am able to detect the address,when i put the wires back i am not able to detect the address.
I tried to get the address after rebooting but no luck, but i am able to get the address after i shutdown the device and on.
How can i make voltage on the uart pins to zero after i change the mode from uart to i2c in order to detect the address of the sensor.
