I have used 5 Oled for displaying 5 different sensor values. It was working fine but when i use bluetooth, one Oled which is connected to GPIO pins 01 and 03 is not working and other 4 Oled are working. If i keep bluetooth code that oled wont work and if i again dump another code which donot include bluetooth program then all oled is working. Why it is happening? What may be the problem?
I have shown pins that i have used for Oled(SDA , SCL) and Sensors(S0-S4) in image below.

That can be anything... BT should not affect I2C communication, so it's either something in your software, or perhaps the extra current used by BT upsets the OLED somehow.
