Hrm, sounds like the BT antennae is weak / not functioning properly. Do you see the same behavior when using the nRF Connect app?
-
A fix for MetaCloud sync has been pushed to the Google Play store (v3.0.2). I have not seen any issues with sharing files through various Android apps. What android device and OS are you using?
-
* Which one of those devices fails to connect / discover the board? * What does startMetawearStreaming do? * Are you resetting the boards before stopping the app?
-
It does exactly what the documentation you linked says it does: The pin’s digital state can be monitored by the firmware, sending the new state when it changes No where does it say the phone is continually polling the MetaWear board.
-
MetaWear can't connect to a host device on its own. It can operate as you described where it internally starts/stops sensors in response to certain events.
-
Yes.

You'll need to provide more information: * What is the model and OS of the Android devices that can connect with the boards? * What about the devices that can't connect? * What code are you running on the boards once they are connected…

Reset the board then try again. It sounds like there are already exiting timers present on the board that were never removed.

@Erika said: I have been testing a MetaMotionR and I would like to use it in different projects but I stumbled upon some problems. Can you please help me with the following questions? It seems to me that data streaming immediately quits wh…

Did you try the commands from the thread you had previously linked? https://mbientlab.com/community/discussion/comment/2085/#Comment_2085 As I previously said, use one of the existing SDKs to program the board how you want, then log the bytes th…

@Manos said: Now regarding the C++ API. Is there a way to stream analog data? I've noticed that when using mbl_mw_datasignal_read your API writes a certain value to a GATT characteristic and then there is a GATT notification that it processes. Ho…

Reset the board to remove the disconnect event.

Swipe the device to delete it, then you can re-add it with a different name.
-
Refer to the unit tests for byte level commands. https://github.com/mbientlab/MetaWear-SDK-CSharp/blob/master/MetaWear.Test/AccelerometerTest.cs MbientLab typically does not support using non-official SDKs so I'd recommend using the unit testing…

I assume those batteries are also now slightly squishy. That means they are dead and should be replaced. Here's a direct link to the firmware that you can use with the aforementioned nRF Connect app.
-
The GPIO pins are only rated for 3V; I would not recommend using that pressure sensor as it's max output voltage is 5V, or you will need to add additional circuitry to protect against overvoltage. Please provide a circuit diagram of your current …
-
Monitor the BT adapter to see what is going on at the Bluetooth level during connectAndSetup. It sounds like the connection is still being flooded with sensor fusion data upon reconnect so you probably will want to program the board to stop strea…

Put the video online, such as YouTube or Dropbox, and link to it in the RMA form.

You can probably find them at hobby stores like SparkFun. I would recommend that you work with MbientLab to do a custom order if you indeed need a bigger LiPo. Before you even decide on that however, you should first test if the current battery …

@max said: One question is, for the above mentioned purpose, do we need all sensors (accelerometer, gyroscope, magnetometer) activated, if not which ones are required to get the information we need? Accelerometer data should be sufficient…
-
No, you should only be using the packed data signals for high frequency streaming and/or streaming from multiple devices. Somewhere or somehow, the boards are still streaming the normal data so you need check your code to ensure only packed signals…
-
Can you try re-flashing the firmware on the device in question? Sensor fusion does not require magnetometer data, so sensor fusion working does not necessarily mean the magnetometer is fine. Another user has brought the same issue up before so i…

* Have the LiPo batteries expanded or deformed in any way? * Are the battery wires making good contact with the the board? * Are the MetaBoot boards not rebooting back into MetaWear mode after 60s? Post the hardware revision of the boards i…

Set the NOBLE_HCI_DEVICE_ID env variable to the hci adapter number of the dongle to use, before executing MetaBase. You'll need to either setup separate config files or use the command line options to pair different groups of devices with each dong…

Code looks correct to me. Based on the notification behavior, it appears that both the normal and packed data signals are being enabled at some point in your code. When using packed data, only the 20 byte data packet should be arriving from the …

Post the full code you are running.

For Mac, we have a Swift SDK so you could use that to stream data from the boards to your Mac, then forward the data to Max/MSP. Weak signals and environmental interference depends on where / how you are using the devices. For example, indoors w…
