How to select alternate I2C address in code?

Hi,

I have 2 SEN0373 boards that I need to connect to the same Arduino, and read from both. 

I can connect one without problem, and individually they both work fine.

Now I have shorted the address selector on one of them, to change the I2C address from 0x68 to 0x69, and connected them both to the same I2C bus.

I cannot figure out how to select the secondary sensor on address 0x69? I assume that I need to create two bmx objects, with something like:

--------------

#include <DFRobot_BMX160.h>

DFRobot_BMX160 bmx160_a; // first device in default address

DFRobot_BMX160(&Wire, 105) bmx160_b;  // Second device on alternate address 0x69h = 105d

-------------

But I get a lot of errors about wrong data types…

Can you please show me how I set the correct address?
