i2c error

[flye]

I just received a new MultiWii Lite Edition Flight Controller V1.0 from rctimer with mpu6050 and I connect it,in gui 2.1 all sensors reading are ok but I get i2c error!Nothing else connected just ftdi to pc!
What does that mean?

It means that communication to a sensor is failing. If the sensor readings are fine, you probably defined sensors you do not have. Like a barometer, compass or i2c_GPS.

Thanks will check that but I only plug it to check if it was ok because I have had 3 faulty one before so they have not loaded the right config on it!
