Hello,

While using data fuser (example code), I'm receiving in both acc and gyro same values. Probably this refers to line mentioned by me here.

Best regards,
Dawid Śliwa

Hi, please,
why is node >= 13 not supported ?
If would it cause any incompatibility ?

Thank you very much.

relevant looking bits of error below:

A client asked me to take a look at your sensor. We are evaluating multiple BLE sensors to use in a mobile application that would be developed using cordova.

Is it possible to use cordova?
Is there a wrapper cordova-plugin available?
Would it be possible to use another cordova BLE plugin like this?

I had to install nvm and go back to node version v8.15.0 for the metawear sdk to install.
It would be great if the package could be upgraded to at least the latest stable version of node: 10.15.0 (at the time of writing).

Hey! I am getting a lot of errors when I am trying to install metawear on Raspbian. I installed everything for Noble before running the npm command. (sudo apt-get install bluetooth bluez libbluetooth-dev libudev-dev)

Do I need more libraries in order for this to work?

I am trying to install metawear package to raspberry pi
OS : Raspbian Buster
Board : Pi 2 Model B v1.1
Node : 8.15.0
SD card : 16 GB Sandisk Ultra

The build hangs after some point and I loose my interaction through terminal though I can receive messages from it.
I am tailing the syslog, it still prints messages but I can not interact with any of my SSH session anymore and have to reboot the device.

This is where node-gyp hangs

g++ -MMD -MP -MF "build/arm/release/src/metawear/dfu/cpp/miniz.d" -c -o build/arm/release/src/metawear/dfu/cpp/miniz.o -std=c++11 -fPIC -fvisibility=hidden -fvisibility-inlines-hidden -Wall -Werror -Isrc -DMETAWEAR_DLL -DMETAWEAR_DLL_EXPORTS -Wno-strict-aliasing -O3 -marm src/metawear/dfu/cpp/miniz.cpp

Output of syslog when the build gets stuck

Do you have any idea to fix it ?

I need to change name of device. I change it using a method in the api, but after the battery runs out, the device name returns to default.
I tried using macro. The macro is recorded successfully, if I call it after recording, the device name changes, but after the battery is discharged, the macro does not start automatically and the script crashes when manually started.
Has anyone experienced this behavior?

Macro example from c++ api:

In this example, we will change the device name permanently:

#include "metawear/core/macro.h"
#include "metawear/peripheral/led.h"

void setup_macro(MblMwMetaWearBoard* board) {
    static auto callback = [](MblMwMetaWearBoard* board, int32_t id) {
        cout << "Macro ID = " << id << endl;
        macro_id = id;
    };

    // Change on boot
    mbl_mw_macro_record(board, 1);
    auto new_name = "METAMOO";
    mbl_mw_settings_set_device_name(board, new_name, 7);
    mbl_mw_macro_end_record(board, callback);

    // Change the name now
    mbl_mw_macro_execute(macro_id);
}

This is probably cpp sdk related, but I'm getting weird values from the battery readings of my MetaTracker.

Voltage jumping from 6 to 27 volts, and charge from 25% to 80% randomly.

Here's a function I use to get the voltage

function GetBattery(device, callback) {
    if(!device || !device.connectedAndSetUp)
        return;

    if(device.battSignal){
        MetaWear.mbl_mw_datasignal_unsubscribe(device.battSignal);
        device.battSignal = null;
    }

    if(!callback){
        return;
    }

    device.battSignal = MetaWear.mbl_mw_settings_get_battery_state_data_signal(device.board);
    MetaWear.mbl_mw_datasignal_subscribe(device.battSignal, MetaWear.FnVoid_DataP.toPointer(function gotTimer(dataPtr) {
        var data = dataPtr.deref();
        var val = data.parseValue();
        callback({
            address: device.address,
            epoch: data.epoch,
            battery: val
        });
        //Unsubscribe
        if(device.battSignal){
            MetaWear.mbl_mw_datasignal_unsubscribe(device.battSignal);
            device.battSignal = null;
        }
    }));

    MetaWear.mbl_mw_datasignal_read(device.battSignal);

}

Is there anything I'm missing? I'm calling this function about twice per minute for now

I don't know if this is the right place to ask or not. I was wondering do you have any plans to support React Native (Since you have JS API) or Flutter in the near future?

Hello,
When i try to do a "npm install metawear", i got this output :
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] install: make OPT_FLAGS=-Wno-strict-aliasing -C MetaWear-SDK-Cpp/ -j
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] install script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Can you tell me please what i did wrong?
Thanks

Hi,

I want to get the raw stream acceleration data using javascript.

MetaWear.mbl_mw_datasignal_subscribe(acc_signal, function(acc_signal){
console.log(typeof(acc_signal));
console.log(acc_signal);
console.log(acc_signal.length);
});

I have get the acc_signal, but it is a object (C++ struct?). I know how to get XYZ values of accelerations in C++. However, what should I do to get the XYZ values in javascript?

Hi,
I have another question, Please help me.

I want to warp JS variables into a struct then pass it to C++ API.

To be specific, I want to call the following API in JS.

    static MblMwLogDownloadHandler download_handler = { progress_update, unknown_entry };
    // start a log download and send 100 progress notifications
    mbl_mw_logging_download(board, 100, &download_handler);

Thanks in advance

I need use with node and Im using the javascript SDK.

Here is my code:

var MetaWear = require('metawear'); MetaWear.discoverAll(function (device) { device.once('disconnect', function () { console.log(disconnect ${device._peripheral.advertisement.localName}`)
})

device.connectAndSetUp(function (error) {
if (error) {
console.log("error" + error)

    }
    console.log(`connected ${device._peripheral.advertisement.localName}`)
});

},true);
`

The code works, I can connect and disconnect, but my problem is when I want to reconnect the same MetaWear, I cant do this and i don't know why.

I have debugged all and I don't find why that happens.

Can you help me please ?

In the official forum of MetaWear is there zero information ABOUT THIS PROBLEM

Im working on MacOS but i have linux too on a rasberry and its the same thing!

Using a MetaHub (raspberry pi 3) running node I discover and connect :

    MetaWear.discover(function (device) {
        device.connectAndSetUp(function (error) {
        ...
        })
    })

This works fine for the first time. Once the pi is restarted, the discover callback is called, then the disconnect event is fired, and the connectAndSetUp callback is never called. I get another discover callback, but that's because I call discover when disconnected, but that's it. The way to make it work again is by opening the Metabase mobile app, choose Diagnostics, connect to the device (connect, it will fail and ask if it should connect again, then it succeeds) and choose Reset from the options to reset the Tracker. After the reset, the sensor can connect again.

The error log is in pastebin:

My current setup is as follows:
Mac: v10.13.6
node: v8.11.3
npm: v5.6.0
metawear: v0.2.0
g++:
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

Hi there,

I'm trying to get the step counter using below sample code in your doc:

console.log('Enable acc steps.');
MetaWear.mbl_mw_acc_bmi160_enable_step_counter(device.board);
MetaWear.mbl_mw_acc_bmi160_write_step_counter_config(device.board);

console.log('Get step signal.');
let signal = MetaWear.mbl_mw_acc_bmi160_get_step_counter_data_signal(device.board);

console.log('Set up read.');
MetaWear.mbl_mw_datasignal_subscribe(acc, ref.NULL, MetaWear.FnVoid_VoidP_DataP.toPointer((ctx, pointer) => {
    var data = pointer.deref();
    var value = data.parseValue();
    console.log('epoch: ' + data.epoch + ' acc: ' + value.x + ' ' + value.y + ' ' + value.z);
}))

console.log('Read.');
MetaWear.mbl_mw_acc_start(device.board);
MetaWear.mbl_mw_datasignal_read(signal);

When I run the JS file using NODE, it juts hangs and not getting any console.logs.

But I can run below methods without any issues:

let acc = MetaWear.mbl_mw_acc_get_acceleration_data_signal(device.board)
let gyro = MetaWear.mbl_mw_gyro_bmi160_get_rotation_data_signal(device.board)

Do I need to include anything else except below? Could you please advise?

var MetaWear = require('../index');
var ref = require('ref');
