Serial communication stops working when SCA and SDA attached

Development Tools IDE 1.x

Hi All,

I have a sensor using i2c communication attached to an UNO which was working flawlessly.
After updating to Arduino IDE 1.8.10 I have been experiencing issues when working with i2c:

  1. Unable to establish i2c communication with sensor. When using the standard
    if (!gyro.begin()) it always gives an error

  2. Serial communication stops working when the SDA/SCL or even A4 or A5 pins or plugged in. This is the case when the sensor is powered and also not powered.... weird.

Can someone please help me? Is this an issue regarding the update or the IDE or my hardware...

Thanks!

Hi,
I went to 1.8.9 and the same issue still exists...
I then went back to 1.8.6 where the sensor has worked before and I'm still experiencing the issue.

Are there other solutions?
Thanks.
