Using BMP180 and myAHRS+ at the same time in I2C

Hello !

I'm studying Attitude indicator for UAV

so have to measure Eulerian angles and altitude.

I used Arduino UNO, myAHRS+ and BMP180 in I2C at the same time

but the I2C addresses of the sensors are crashed.

can I change the address of BMP180 with Arduino code?

if It's impossible, I'll try to use UART on myAHRS+ and I2C on BMP180

Can I get some codes for using UART and I2C at the same time?

I just buy a I2C multiplexer !
