ant-plus's Issues

is_present( ) causes the stick to close

When I call is_present( ), the stick seems to close... or otherwise put the object in a bad state such that write( ) fails and throws and exception.

if (!this.stick.is_present()) { .. }
I've verified open() returns true before calling is_present(), and then after calling is_present() I verified open() returns false.

See ./src/ant.ts file.

Samples crashing with cryptic stack trace

Hi! I'm having trouble running the samples for this library. I can only assume it's something weird with my setup, yet this issue occurs both on my linux PC and my raspberry pi.

When I run sample.js on my PC, I get this ugly crash:

node[4071]: ../src/node_api.cc:1149:napi_status napi_release_threadsafe_function(napi_threadsafe_function, napi_threadsafe_function_release_mode): Assertion `(func) != nullptr' failed.

10: 0x13ff159  [node]
[1]    4071 abort (core dumped)  node sample/sample.js

To be totally honest, I've no idea what's happening here. Any pointers would be welcome.

Curiously, on my PC, this only occurs after the first time I plug in the ANT+ dongle. If I unplug and replug it, the script works as expected. However, I get a very similar crash on my raspberry pi, and replugging the dongle does not seem to make a difference here. This is the exact crash I get on the Pi:

node[6930]: ../src/node_api.cc:1275:napi_status napi_release_threadsafe_function(napi_threadsafe_function, napi_threadsafe_function_release_mode): Assertion `(func) != nullptr' failed.
Aborted

Looks like it's the same issue.

I have tried various node versions (14, 17) and multiple ant+ dongles. The same issue is also present on my laptop which is similarly set up to my desktop. I feel crazy that I'm having this issue on 3 computers yet I'm struggling to find any evidence of similar problems! Any pointers big or small would be hugely appreciated. Let me know if I can provide more info too!

List of supported devices ant+ to usb

Hello. Please tell us what devices can be supported by your program? Is it possible to use an ant+ to usb device from the brands THINKRIDER, Magene, Cycplus, Coospo? Tell me which of them will work with your software?

Unable to find USB device while running on Windows system

In the Windows system, the ant. js file -- open() method cannot retrieve information about the inserted USB device.

Max sensors limit?

Hello, I would like to know how many sensors would it be able to connect simultaneously? Usually with a USB dongle is 8, but I wonder if it could reach this limit or even overcome it. Thanks

Problems with SpeedCadenceSensor, extreme numbers

Hi,

I am having problems with numbers from this. Any idea what could cause this?

I get maybe 5-10 events with numbers that looks reasonable. Then suddenly I get events like this:

SpeedCadenceSensorState {
  DeviceID: 7434,
  CadenceEventTime: 65362,
  CumulativeCadenceRevolutionCount: 1279,
  SpeedEventTime: 0,
  CumulativeSpeedRevolutionCount: 13222,
  CalculatedDistance: 28321.523999999998,
  CalculatedCadence: 7630.816999805938,
  CalculatedSpeed: 446.5095314313867 }

  // Some milliseconds later:

SpeedCadenceSensorState {
  DeviceID: 7434,
  CadenceEventTime: 56336,
  CumulativeCadenceRevolutionCount: 65535,
  SpeedEventTime: 585,
  CumulativeSpeedRevolutionCount: 0,
  CalculatedDistance: 112056.58799999999,
  CalculatedCadence: 69861.7703061405,
  CalculatedSpeed: 196146.9164307692 }

The revolution count is maxed out, and thus the calculated distance and speed is all over the place. Then the next packets all have the same cumulativecadencerevolutioncount, but CumulativeSpeedRevolutionCount is going up and down in numbers. But seems like a much higher number of revolutions than the wheel is actually spinning.

TypeError: Cannot read property 'assignChannel' of undefined

Bug in ant-plus.js that is missing this line in the module.exports = { } block:

After I added that line to the other exports, the error disappeared and the stick initialized fine.

LIBUSB_ERROR_BUSY

This is a great library, was very easy to get started with after trying the python equivalent for raspberry pi.

After initially running just fine though and a few restarts, I then got the following error:

What happens if you attach a sensor, but no device is found?

I don't understand what happens if you attach a sensor (attach(0, 0)) with 0 as device's id to connect to the first device found, but no device is found.

How can I know when I can try to attach again? Is there a timeout or an event to catch?

Thanks,

Attaching multiple HR sensors

Hello, I wonder what is the proper way to use multiple sensors at the same time. I'm trying to attach 8 hr sensors and right now I'm getting: " MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 read listeners added. Use emitter.setMaxListeners() to increase limit" even with just two of them, so I think I'm not attaching them well. I have that warning until I increase the limit to 1000, and that doesn't seem right.

stick0.on("startup", function() { console.log("startup stick"); console.log("Max channels:", stick0.maxChannels); // will output 8 hrSensor0.attach(0, 0); hrSensor1.attach(1, 0); ...
I'm just attaching the sensors on the stick startup using DeviceID=0 for all of them because I want to be able to attach to any hr sensors, not only the ones I know. I wonder if I could scan the DeviceID before attaching it.

I know I should follow your instructions. So I'd like to know which is the best way to do it:

never attach a sensor before receiveing the startup event
never attach a new sensor before receiving the attached or detached event of the previous sensor
never detach a sensor before receiving the attached or detached event of the previous sensor

Do I have to attach the sensors recursively then? (I did and that seems to make the limit warning disappear) Should I detach every sensor just after it's attached to reattach it again with its real DeviceID?

The lib gives also an exit error if I ever try to attach o detach a sensor that is already attached o detached. Any way to prevent that beyond making sure of not doing that?

This is the best nodejs ANT+ lib I've found. Thank you for your great work.

Issue in Readme: Scanner vs Sensor

I tried following the docs after installing my ANT+ stick via Zadig.

I tried to call sensor.scan() as descripted in the README.

But i kept running into this error:
FATAL ERROR: Error::Error napi_create_reference

I had a look, and it looks like you have to create a HeartRateScanner if you want to scan for devices.

A HeartRateSensor, if you want to attach a device.

This is not clear in the README.

(please correct me if i am wrong)

Can't receive data from multiple sensors at same time

I'm programming a Electron app.
I did attached HeartRateSensor on channel 0 and SpeedCadenceSensor on channel 1.
However, I've received only heart rate data in spite of SpeedCadenceSensor did attached.
But, if I replace the channel, I can receive heart rate data instead of speed data.
I need your help.

App stuck due to 'SYNC missing'

Hello

After an app using the ant plus module is running for a few days (detecting heart rate sensors) -
the app occasionally get stuck and the following error is thrown - 'SYNC missing'.

I found that error in the 'ant.ts' file:

if (data.readUInt8(0) !== 0xA4) { throw 'SYNC missing'; }

My app is running on Raspberry Pi 4.

The only solution is to restart the hardware. Restarting the nodejs instance won't help.

I'd like to know what's the reason the module gets stuck and what can I do in order to solve it.

Thank you

SimulANT+ compatibility ?

Hey

I am pretty new to ANT+, and trying to use SimulANT+ app to simulate sensors on GarminStick3.
(will have real sensors to test soon, but i am trying to pre-test via SimulANT+)

The issue is that the ANT+ stick is not visible to the SimuANT+ app if i install it as WinUSB (libusb).

If i install the stick with WinUSB (libusb) , i recieve the startup event fine in ant-plus, but it does not show in the device list of the SimuANT+ app.

If i install it as libusb-win32, it shows up in SimulANT+, but i no longer recieve any startup event on the stick in ant-plus.

I do not get any Stick not found!message either, even tho i have the check

if (!stick.open()) {
	console.log('Stick not found!');
}

Anyone else tried this ?

Is it a known limitation that SimulANT+ needs a different driver than ant-plus ?

SpeedSensor should attach at 8118 instead of 8086

Hi,

(Thanks for this project, it is so great ! It's working perfectly with my Favero Assioma power pedals)

i wasn't able to received any data with my Garmin Speed sensor.

Then i read the documentation (D00001163_-_ANT+Device_Profile-_Bicycle_Speed_and_Cadence_2.1.pdf) and realised that the period of the speedSensor is different that the one for Speed+Cadence.

By changing the period to 8188 i'm getting the datas.
(maybe your speed-sensors.js was created after copying speed-cadence-sensors.js

Zadig WinUSB installer in Readme.md is out of date (Win10)

The version of WinUSB / Zadig pointed to by the Readme.md is a n old version on SourceForge. The correct version to use is the one on the Zadig website https://zadig.akeo.ie/

With the version in the Readme, I could not get the lib to work on Win 10. The updated version works correctly.

What's the meaning of attaching HR sensors ?

Hello

I am able to receive the HR data from multiple devices using only 1 sensor initialized.
In every beat I receive hbData simultaneously from all devices and store the data according to the given serial number.

I never call the attach method and actually don't understand why I need it all, or what's the meaning of attaching the sensor to a channel.

Can anyone help me figure this out?

Thanks!

Generic type/scanner?

I'm trying to connect to my Di2 system on my bike and see when the hood-buttons are pressed but Iv'e heard they use a pretty custom profile

Is there a way to just connect to all/any Ant+ devices and spit out any raw data that may come from them?

Mac compatibility?

Hi there! I want to know if there is a way to run this on a Mac? I saw that windows and linux versions uses different kind of usb connectors. Do you know how to do it in a Mac?

What is the time interval of the output data?

Hi,

I have managed to get reading from my power meter. The output data is pretty frequent. May I know what is the time interval between each data and can I change that interval? If so, how? Thank you.

Option to use WebUSB api

Feature request/ proposal

I am looking at getting this working with the WebUSB api which:

• Is available in Chrome 61 for Android, Chrome OS, Linux, macOS and Windows.
• Has a port for Node.js also exists - https://github.com/thegecko/webusb

we could there for have a cross platform ant plus driver, which would work through node or a recent enough chrome browser. We should even be able to drop back to node usb module for compatibility.

What do you think?

RSSI (Received Signal Strength Indicator)

Hi

I hope this message finds you well. I am using the ant-plus library to capture heart rate data from a Polar Verity Sense sensor. While I can successfully log the heart rate data, I am having trouble extracting the RSSI (Received Signal Strength Indicator) value.

Could you please provide guidance on how to correctly obtain the RSSI value with this sensor?

Thank you for your assistance.

Best regards,
Nuri

Event is not emitted for SpeedSensor

The event speedData is not emitted when using SpeedSensor but is emitted when using SpeedScanner.

Best strategy to scan after atached?

Hi everybody,
I am starting to play with this nice package, I have searched in examples and code and dont find the way to scan after been attached a sensor.
Let say I have many devices but only one stick: hr sensor and fitness sensor, scan for fitness and select one to attach it, after I would like to scan for hr devices but.. message error is returned mentioning "cant attach".
Is there any way to cover this use case?
Should I deatach fitness, save it´s ID, scan for HR and when select HR sensor and attach it, attach also fitness sensor in another channel?

Kind regards and thanks in advance

Adding bicycle speed/cadence sensor

I'd like to capture data from a Garmin GSC-10 speed/cadence sensor I've got attached to my bike.

It looks like this is a different type of device than either the heart rate monitor or the stride/speed/distance sensors currently in the repository. How would one go about adding this sensor type? Is there a website for ANT+ sensor specs I could reference, perhaps?

No data event

I do not get any data, I did open zwift which tells me my heartrate, so the dongle is doing its thing. I'm using OS X.

Muscle Oxygen Monitoring support?

Will there be that support? or how do I develop it?
