The NDoF is working as intended; it is the one Bosch has created and is used by companies like Apple. Did you confirm there was no magnetic interference?
-
Did you check if they are already installed? If not, can you google-fu something for your specific macOS? I know Catalina did change a lot of things.
-
You can calculate absolute orientation from a know start + relative orientation.
-
It is relative orientation.
-
The sensors are factory calibrated. This is normal behavior.

Thank you for clearing that up @alexdpoon We don't officially support our Node.JS/Javascript APIs on MacOS at the moment and the tutorials your are using are not meant for MacOS Node installations at all. Again, we do not support MacOS + Node.…
-
What are you trying to install? What is your end goal?
-
Our APIs get the data via the bluetooth link from the sensors (our APIs just talk to the sensors over BLE). You can do anything you want with it after that. That means use mqtt to send it to your amazon instance, email it to yourself, store in…
-
Our sensors use bluetooth, not wifi or lan.

Please see this: https://github.com/mbientlab/MetaWear-SDK-JavaScript/issues/11
-
No, there is no workaround.
-
Python is great but the bluetooth third party libraries we use are more robust and reliable on Javacript. If you are doing something simple, Python is the way to go. If you have multiple dongles and sensors, Javascript is the way to go.
-
@qpal1012 You are correct. There is no hidden elements or secret sauce, we simply use our APIs which rely on the Bluetooth Core libraries from Apple. You can check out our sample App as a good starting point.
-
Hi @kracikiran, We don't support serial communication. Only Bluetooth low energy.
-
We are working on it but I don't expect it out until two months from now.
-
The iPhone allows only up to 6 connections at once and I have only been able to get 3 sensors connected at the same time reliably (that's iOS for you). Basically you cannot do this with an iOS App; you need to do it with a mini Linux PC like a rasp…

@Steve26 Thank you for the update. While I don't have enough information to say why the previous dongles worked or didn't work, it is likely that the drivers weren't installed properly (or maybe they were just bad...). You will have to write yo…

This is already mentioned in another thread on the forum and is also in our tutorials.
-
@slee, So the metabase app works? Let me know, I can look up the config.
-
Unfortunately it is not our sensor fusion. It is the Bosch sensor fusion module. Maybe you can post your findings on their forum.
-
As I suspected. Please read the first line on this page in giant red letters in the Product Details section: https://mbientlab.com/store/mmrp-metamotionrp/ A coin vibration motor = magnet A magnetometer = measures magnetic forces Therefore: …
-
It is in the tutorials, read the entire thing and go through all of the examples.
-
Make sure to only have 1 dongle and get that dongle working first before using another.
-
Combine examples and learn; you got this.
-
It's in the tutorials.
-
is it a MMR+ or MMR?
-
You should look up gimbal lock and learn more about the shortcomings of euler versus quaternions. This might help clear things up a bit.
-
I am not sure exactly what you need here but you have to stop everything: 1. sensor fusion stop (this doesn't stop the acc or gyro, only the sensor fusion library) 2. gyro stop (this stops the gyro) 3. acc stop (this stops the acc)
-
The MetaBase App should not be able to do this.
-
Use bluetoothctl to find out why 00:1A:7D:DA:71:10 isn't working. Also you have two controllers with the address "00:1A:7D:DA:71:10", remove one of your dongles as Python doesn't know which is which and rerun your script using that dongle.
