Yes, the App doesn't fully support the MTR unfortunately.
-
@mamdouh, It's most likely a spike when Bluetooth or a sensor is turned on. For a micro second, something might demand a few milliamps of current to start running in so creating a spike. This is 100% normal.
-
Just update the pods and get it to work on the latest Xcode.
-
Good idea to use an event to sync, that's a great way to go. There's always going to be latency in the BLE so that epoch will never be perfect but thats ok. The error rate is low/minimal and you can do some post processing to minimize it.
-
Can you fix the formating or send code as an attachment?
-
Thanks for the update @Salvo_mon
-
Hey have you been able to get this working?
-
Hi Sarth, You have a good idea there. Unfortunately we don't support this.
-
I am not sure, I don't use Xamarin.
-
Yes it is. On our sensor side, see our APIs regarding connection settings. On the Python side, we use a 3rd party library called PyWarble which is a wrapper around the C library called Warble which is a wrapper around libblepp (a version of BlueZ…

Please note we just released firmware 1.5.1 for a fix.

Hi, We do not currently support USB data. However, in our new sensor called the MMS coming out in 2021, we will support the latest Bluetooth spec as well as USB data downloads. There will also be additional memory on the MMS devices. Stay tuned!
-
Hi, You already have the latest firmware for MTR. 1.4.5 is not supported.
-
Hi, MTR is not supported on firmware 1.4.0, 1.4.5, 1.5.0, 1.5.1. You already have the latest firmware installed for MTR. Please note we are phasing out the MTR in 2021.

We already provide a sample iOS App on github: https://github.com/mbientlab/MetaWear-SDK-iOS-macOS-tvOS/tree/master/MetaWearApiTest This is documented in our tutorials.
-
Windows doesn't support more than 1 BLE dongle/antenna and almost all dongles/antennas don't support more than 3 connections. What you are trying to do is outside the realm of possibility with Windows. You should be using Linux. In fact, we…

Have any of you tried to change the BLE connection settings between the devices? This might solve your issue. Also, when iOS updated to BLE5, the default conn settings changed.
-
Again if you have a MMR+, the coin vibrator motor is a magnet and will give you erroneous magnetometer data. This is well documented on our product page and tutorials. For maximum performance, the battery should be as far away from the board and …

Epoch time is the time at which the computer gets the sensor data. So that's why you see some minor changes. The sensor is sampling correctly so the deltas are correct but the epochs granularity won't be because there are minor delays from the BL…

If you developed on iOS, there is some amazing tools already made for this: https://developer.apple.com/machine-learning/create-ml/
-
Always make sure to keep Xcode updated. Also since we use a bridge between our C APIs and swift, sometimes it may take a minute for Xcode to process.
-
Hi Hugues, We are no longer going to be supporting Windows. Please use our iOS or Android Apps to download the data. Linux works too.
-
Most likely the bluetooth was interrupted and the download didn't finish.
-
Unfortunately both gyro and acc at 800Hz is not supported. Only 1 or the other. Otherwise you need to lower the frequency (the MCU can't handle processing that much data and the memory runs out quickly).
-
HI @peacesheet, Due to the pandemic we are no longer offering services. Sorry for any inconvenience. The only time we do customizations is on large custom manufacturing batches (500 MOQ because then it can be done straight at the factory).
-
Will the battery last for 8 hours? Yes. And how long does the recharging take? 15 minutes for a quick charge. 2 hours for a total charge. I also saw the following statements from the website, does anyone has any experience with bigger batterie…

The phone should have the ability to download, can you double-check? If you are comfortable with basic programing and our APIs, you can run our anonymous download script for Python on Windows.
-
You would want to do a single read like we do in our temperature example.
-
Can you try to do it with an iPhone?
-
Can you send replicable steps and code in .txt file?
