Hey @arsalan26666, I found out that the MetaHub MetaBase app hasn't been updated for the MMRL and MMS yet. I should have updates shortly.
-
Thanks @Adam_B
-
I don't think the calibrate.py example works for the MMRL or MMS. It was made for the MMR so I might need to check if it needs updates for our new sensors.
-
USB download via MMS will be available in about 1 month.
-
You can use the reset() function if need be to turn off the LED. There is also a function to turn off the LED that you seem to be using but you must be using the call incorrectly somewhere. Not enough info to comment further.
-
Not enough information to comment at this time.

Hi @ericf, That's normal because the latest Android SDK requires that each App have its own storage that is not accessible by other Apps. BLE is inherently slow so that is normal. It may look like 20s on one device and 10m on the other but it's no…
-
At the end of the day, BLE is not very fast. That's why we release the MMS and it will have USB download available shortly (in about 1 month we will release this feature).

-bash: cd: Apps/MetaBase-Node/: No such file or directory
-
Why can't you do: let _self: ScanCode = bridge(ptr: context!) _self.deviceArray.append(quaternion)
-
Hi @ThomasMcGuckian We are currently working on it but that is exactly how it will work. We are hoping to release in the next few weeks. When do you need it by?
-
Hey @Adam_B So to replicate I just need to group 3 sensors in the MetaBase App and have them stream or log sensor fusion? Can you send me full replicable steps so I can reproduce this on my side. Also was this the iOS and Android MetaBase App? S…
-
Then it means you did not format the config file properly. Make sure its in proper json format.
-
Bluetooth limits the total data rate at 100Hz. You are trying to push something like 250Hz of data through... Read the README and tutorials throughly first.
-
Does the MetaBase App from the app store work?
-
Why don't you look on github for this? This isn't an API question but a general coding question. * https://github.com/srvds/Human-Activity-Recognition * https://github.com/laxmimerit/Human-Activity-Recognition-Using-Accelerometer-Data-and-CNN …
-
Unfortunately we don't allow that currently. We may enable this feature in the MMS in the future. Can you use our data processor to lower the sensor fusion data rate?
-
Hey @Jonas_MCI, Welcome. Let me know if you have any other questions. It seemed to just be a matter of figuring out your setup / system architecture. With 8 sensors, Linux really is the way to go (smartphones have too many limitations).
-
So the MetaWear time is internal to the Sensor itself. That's the clock in the CPU of the MetaSensor. The Java timer is in the App only (the sensor doesn't know anything about this timer).
-
Looks like either gimbal lock or magnetic interference.
-
Hey @Jonas_MCI 1. Yes but again you have to do 4 sensors per dongle so that's 25Hz per sensor so that 4 sensors = 100Hz total per bluetooth antenna. 2. . 3. You are right, 12.5 to 800Hz (not KHz). 4. . 5. . 6. If you have a faulty sensor let'…

HI @Xiaorui, Unfortunately we don't support USB connections for the MMR.
-
Hey @jjm345, can you be more specific?
-
* Yes but you have to do a semi custom Metahub setup. * * Yes, streaming tops out at 100Hz total PER BLE antenna. You can log internally at 800Hz. * We are not supporting Windows at all at this time. * See #1 and #3
-
@patrice, Thanks. I might release officially soon. Just making sure Xcode 12 stabilizes a bit.
-
Hey @atonino, can you confirm your fix?
-
You might be able to do something like this: protocol TutorialDelegate: class { func newDataPoint(value: CGFloat) } class Tutorial { public weak var delegate: TutorialDelegate? var device: MetaWear? func accelStream() { …
-
@Mitch2446, it should be something like: @IBAction func startPressed(_ sender: Any) { let board = device.board guard mbl_mw_metawearboard_lookup_module(board, MBL_MW_MODULE_ACCELEROMETER) != MODULE_TYPE_NA else{ print("No accelero…
-
@iamjannisgrimm that is right, the line let _: NextViewController = bridge(ptr: context!) does nothing since @Mitch2446 doesn't use it. // Some class class MyClass { // Some Data Point Saving function func newDataPoint(value: CGFloat) …
-
* It is not possible to connect to 8 sensors at once. Please clarify. * The MetaBase Metahub app does this. * I think you issue is that you are not following the Bluetooth and OS level parameters. This has nothing to do with our sensors but rather…
