Hey everyone!
I am trying to make a data mining project. I want to use a gyro/acc board on an item that moves up and down. I want to add a second board to another item so I can read this one as well. I want to collect the data via bluetooth.
So my question is can you read in two separate boards via bluetooth? Read it from a PC or Phone? I am pretty sure you can do one board, but wasnt sure how or if I could do a second board!
Your help is well appreciated! 
Not without some processing in the middle, even with only one gyro/accelerometer. Gyro/accelerometers do not come with ready-made bluetooth transceivers on board. So you need some sort of microcontroller to read both out over whatever interface they require. Then have the microcontroller translate this to a combined data stream which the bluetooth module is happy to accept and transmit. And then the app on your pc or phone would need to be able to seperate them again. Ready made solutions for this? I don’t know of any.
I think he’s asking about reading multiple bluetooth devices. That is possible since you can pair as many as 32 (I think) active bluetooth devices at once.
