I have used 5 Oled for displaying 5 different sensor values. It was working fine but when i wanted to 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 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.
