ANT USB with more than 8 channels

2025-03-21T08:08:23+00:00

Hi everyone,

I want to build an application which allows to receive data from multiple heart rate monitors. At the moment I use a Ant+ USB2 dongle which has 8 channels. As I want to implement this in a gym (for example in a spinning class), I would like to be able to connect to more than 8 heart rate monitors at one time. Does an ant+ receiver/emitter with "industrial standard" (e.g. more channels available than 8) exist or is the only option to manage multiple Ant+ USB2 dongles?

Thank you!

ANTUSBstick on MaOS

2025-01-24T10:35:48+00:00

Hello everybody,
I'm having difficulties on seeing the USBstick2 on my MacOS. I can see it on system informations, meaning that the physical connection is there, but it cannot be seen as a serial device for communication. Opening the IORegistryExplorer i can see that the bDeviceClass of the stick is 0x0, and that seems to be why it is not read as a serial USB device. On other parts of the forum and in general on thisisant i have found many times written that Macs do not need the installation of any additional drivers in order to read the stick correctly. Unfortunately the driver that used to be native of Macs has been deprecated in version 10.x.x. I'm currently working with Sonoma 14.0. So to sum up, i want to ask if any of you knows how to read correctly the USB stick from a MacBook. (I have also installed ANTWareII, but it cannot see the stick). Thank you in advance.

Can I use a custom nRF-based USB dongle with the ANT_Managed_Library?

2024-02-27T10:05:53+00:00

I am trying to upgrade one of our systems from a ANTUSB-m dongle to something with a bigger antenna, hoping to improve reception.

However, ideally we wouldn't want to rewrite our C# code base because of this swap... Therefore, I was wondering what are the requirements for the ANT_Managed_Library to recognise an nRF device? I had a look at some documentation but I could not find any confirmation if this was possible at all (nor that it was not possible!)

Can somebody please help me with this?

Can you share ANT_MESSAGE explanation

Hi ANT support team.
I am searching documentation to understand all ANT_MESSAGE
Can you share me document?

GFIT GAP Appearance

2023-07-11T09:11:51+00:00

Hello,

why is the Appearance (0x2a01) under GAP (0x1800) set as [5184] Generic: Outdoor Sports Activity when the GFIT module is configured as Indoor Bike ?

And there is nothing in the documentation to be found on how to change that.

Thanks ahead,

Andre

ANT+ USB-m not being recognised by Windows 11 Device Manager

2023-02-23T12:17:24+00:00

I have a Levono X64 system laptop running Windows 11. I have a GARMIN USB-m stick which works in my partners laptop (also running Windows 11) and also works in my old laptop running Windows 10.
When I plug the USB-m stick into either of the 2 available USB-3 slots, the device does not appear on "Device Manager".
I can see that all the relevant drivers are installed.
From the above information it is evident that the problem is not with the USB-m device as it works in other machines. This would suggest that the USB port/slot is not working properly however, plugging other devices (USB Memory Sticks, iPhone, Garmin watch data/charging cable etc into these USB slots these devices are instantly seen on Device Manager and work correctly.
I have also tried a friend's GARMIN USB-m stick in my laptop that he knows works in his laptop, and I still have the same problem. Also, my USB-m works in his laptop.

Have you come across this anomaly before and is there any help you can give me?

Yours hopefully

ANT+ support for RPI compute module

2022-05-25T14:49:30+00:00

Hi all,

I am investigating options for a project where a raspberry compute module should be used as the main processor. The project should also have ANT+ support. The software running on the module should be able to receive ANT message and parse them. Is this something which can be achieved natively? The RPI module has built in support for BLE. Or is it necessary to add an external chip? If yes, are there any recommendations for something which does not require extensive coding of kernel modules or am I better of by just connecting a cheap ANT usb stick to the module?

Thanks for your help!

Installing ANT USB Drivers for Windows 11

2022-03-15T17:29:23+00:00

Windows 11 currently does not automatically download the required driver for ANT USB-m sticks. Following the procedure below will resolve the issue.

To manually download the driver:
1. Login to thisisant.com
2. Navigate to thisisant.com/developer/resources/downloads
3. Under "SOFTWARE TOOLS" download the "ANT USB Driver -Windows" driver
4. Unzip the newly downloaded .zip file

To update the driver:
1. Plug in a ANT USB-m stick (or ANT USB2 stick) into a USB port.
2. Open Device Manager (Start Menu -> Device Manager)
3. Locate "ANT USB-m Stick" under "Other devices"
4. Update the driver
a. Right click "ANT USB-m Stick"
b. Select “Update driver”
c. Select "Browse my computer for drivers"
d. Browse to where the unzipped driver folder is located
e. Click "Next"

ARM64-based Machines
ARM64-based machines require different drivers, but we do support the cross-platform Microsoft driver (WinUSB). The existing driver (libusb0.1) doesn’t work, however, we have a UWP version of ant-lib which uses WinUSB. There is a beta version of it up on the website, located here:
