I just have to get by the shop and solder in the pins before I can
play with them. I have 4 other IMU's to tinker with but this is the
first (too bad it had to be Bosch) that has the "sensor fusion"
already built-in. What Bosch did was include an embedded uprocessor
and developed their own code. I cannot find out if they used Kalman
filtering or not, or exactly which algorithm they selected. I
*greatly* enjoy not having to write that code and optimize it for an
embedded box so if this works, I consider it money well spent.
However, Bosch does not have a great track record in that respect.
Plus, the more cpu load I can offload from the BBB, the better I
like it. :)<br>
I'm also using the Adafruit "ultimate gps" board (MTK 3339) for the
same environment. Running tests now to determine the lowest
processor overhead involved with just talking to the danged thing.
Read() a char at a time, or string at a time. Which method uses the
least overhead? And worse, getting a line at a time doesn't know
when to stop because the gps out uses Winblows CR/LF instead of the
UNIX/Linux '\n.' Using read() with fixed buffer size is reading
PAST the end of line into the next line because of that. Grrr.
Searching for problem resolution now.<br>
Minicom source has both methods in it's algorithm but I can't
determine which is used in their runtime. Their output from the
serial GPS strings looks correct but I can't get my program to do
that in canonical (get string mode) to do that. Probably
"programmer head space" error.<br>
<br>
This toy has applications in several areas, including drones and
etc.<br>
<br>
I want a drone so bad...<br>

to pick up some! If you find some success with these maybe toss

Thanks, Matthew, I downloaded that before I bought one to be
sure it would work for my application. Are you by chance
playing with them, too?<br>

playing with the Bosch BNO-055 units, with internal
"sensor fusion" already built-in? I just received two
of them and can't wait to solder the pins so I can
tinker!<br>
<br>
Any comments about the device? They're a bit less
than $35 for a Teensy 3.1 compatible board. I plan to
use them with a Beaglebone Black. They are 3.3V units
and use I2C.<br>
