Hi,

I have a question about using multiple sensors on the same I2c line with multiplexors.
It seems that using this library, whatever mux I am connected to at the time I create the:
var bno = new BNO055({device:'/dev/i2c-1'})
is the only sensor that has ever has values available for analysis. The others all have 0's.

Has anybody run into this? Any suggestions would be greatly appreciated.
Thanks

Hi,

I am having an issue creating a bno object with /dev/i2c-1 and /dev/i2c-6 in the same program. There seems to be a memory leak when doing this. Has anybody ran into this, and encountered some kind of resolution?

It looks like this defect may be related to an issue on Kelly's I2C library, but I cannot be 100% sure.

Thanks

could you please give installation instructions :)

thanks in advance

The repo was probably deleted, this module node-BNO055 doesn't install any more.

Hi, I am having some trouble with the following mysterious error that involves the i2c.node file, which is not readable.
