Have you considered using Bluetooth? I have connected a single Bluetooth tracking device (not from M5) to Unity without too much trouble. I believe Bluetooth supports up 7 clients connected at once.

RE: live motion tracking with multiple m5stickc in unity [QUESTION]
RE: M5stickC and VL53L1X sensor GROVE port
I tried the VL53L0X unit on the grove port of the stick several times and could not get it to work. I know that really doesn't really help you but at least your are not alone in this quest :)
RE: Too into the stick?
@ajb2k3 That group was actually part of an order of 20. I am using them to teach a series of workshops called "Beyond the Arduino" http://tinkerfarm.net/workshops/m5stickc-workshop-2019/.
The idea is that you can learn basic Arduino using the sticks but then you can go much farther with the extra on board hardware or expansion via the grove port or header pins. Just finished the first one and I have learned getting people comfortable with the setup process--how to expand the Arduino IDE past the built in boards and libraries by itself expands their horizons on what is possible with micro controller platforms.
RE: All my sticks are defective...
For whatever its worth: I bought 3 to experiment with and they were all fine. I just tested 20 more that I bought for a class. 17 started up in the factory test program. The other 3 had no software installed but worked fine after I downloaded the factory test example.
RE: What grove modules are compatible with the m5stickc?
I have posted my notes on using the stick with some Grove modules (over the grove connector) here: http://tinkerfarm.net/projects/the-m5stickc/m5stickc-hardware-accessories/
RE: Ultra Low Power Stick, Is There a Market?
It would be a good project but would result in a completely different product. For greatly extending the run time of the existing product how about a large external battery such as a power bank connected to the usb jack? Quick, cheap, and easy and should do fine for demonstrations and prototyping.
RE: Does the Env Hat cover the IR and LED?
@pgb The case of the ENV hat definitely covers both. I posted a pic of the insides here
It would be pretty easy to open the ENV hat with a hex wrench and drill out a hole so the LED is easily visible without damaging the ENV hat. The IR transmitter might need a light pipe (if those work for IR).
RE: M5StickC: turn off screen completely
@multihelix It's not going to happen. There is no way to turn the backlight or the rest of this device completely off. I think of the on board battery more like a super capacitor, it gives you enough power for a few minutes of testing but for anything else you need an external power supply with a real on/off switch.
