using multiple imu 6dof v2 concurrently

Wireless & IoT
1

Hi all,

Quick question here that I hope someone has a solution to - the imu 6dof v2 units I’m working with all have fixed MAC addresses, which means that a sweep for bluetooth devices will only return one of them at a time (I’m using BlueSoleil). Is there a way to connect to multiple imu 6dof v2’s simultaneously, from the same computer?

Thanks,

Stephen

Bluetooth can only emulate one true serial place at a time. What is your application 2 imu at the same time?

Hi ylim: I’m not sure about having only one “true” serial place at a time, but it is possible to have multiple imu’s running simultaneously. As it turned out, about half of the imu 6dof’s I have used a different bluetooth module (I think from roving networks? They show up as firefly-xx instead of SparkFun-BT) which have different MAC’s. In the end, I was able to connect to and receive data from 2 imu 6dof’s and 4 witilt’s simultaneously over 6 different serial connections (via PuTTY on Windows).

I might be wrong but this is interesting? Did you look at timestamping?

I did read somewhere that that a single bt dont support true multiple serial somewhere.

Which version of IMU are we looking at? v4?

hey, i tried to download the putty and cannot seem to start it and keeps hearing the beep sound, you have any idea what can be wrong? no serial communication is initiated. things are okay with hyperterminal.

i got it sorted. thanks.
