ANT Forum

Hi,
We have a client inerested in implementing a control for Heart Rate device and we are assessing contract the support for developers of ANT+, but we need know if it is possible obtain a lists of devices found and obtain the device number id for setChannelID in WPF.
The sample ANT_NetDll_Demo It has not implemented this option, and we have not found a sample for it
There are some sample, document or link to implement this?
Thanks.      

Don't any update thread? The client is asking me urgently a solution and if we can't use the solution thisisant we have to chooser other as polar ( http://developer.polar.com/wiki/Bluetooth ) that have a documentation more accurate.      

Hi,
Sorry the website has undergone some migration work so I lost track of some threads here.

Are you only needing to receive data from 1 strap or from more than 1?

Yes, you may use extended device numbers to capture the channel ID from multiple ANT+ HR straps. You may use either continuous scanning mode, or a background scanning channel to receive the Channel ID from any number of straps, and then pass that channel ID for opening a slave channel. This is detailed in several application notes.

There are also several ANT+ Members which provide products for this type of use case which may be useful. One of them kindly presented at the most recent ANT+ Symposium Conference on the advantages of ANT+ in tracking heart rate data in a group/gym environment, and also published a white paper discussing the issue:

COLLECTING USER PERFORMANCE DATA IN A GROUP ENVIRONMENT

For your actual coding, you will want to use the C# library in the ANT Windows Library Package.
As well there's an app note discussing how you can get started:
ANT AN Getting Started with ANT PC Development

For example code, I would look at the ANT+ RSSI Demo, which implements the type of listing you are looking for.

Hopefully that's enough for you to get started with .

Hi, thanks for you answer.
I need receive data from more than one strap.
I have a problem with the ANT+ RSSI Demo and me device. Give me an error: "Not a CC257X module".
My device is a Heart Rate Monitor of B'TWIN: https://www.thisisant.com/directory/heartwear-ant-cardio-belt/
¿Could not be this device compatible with RSSI and search devices?
     

Any answer?
For more information, our usb for connect with B'TWIN Heart Rate Monitor is this: https://www.thisisant.com/developer/components/antusb-m
And not found with ANT+ RSSI Demo, isn't compatibility?      

The USB-m does not support RSSI, but the demo is still a good source for how to show device numbers. You can make a quick edit to the source code to allow the app to connect to other USB sticks such as the USB-m (although the RSSI will not work properly).

In the "MainForm.cs" file, comment out this line:

     

Thanks for you answer, i got obtain device list!
But the ANT_NET.dll that is in ANT_RSSI_Demo obtain a error of capabilities or baudRate. I replaced the ANT_NET.dll by ANT_Managed_Library of ANT Windows Library Package and the error disapear.
Also I had add ANTLIB_CONFIG_0x6E to ANTMessageID and decrease MaxThreshold to -128. With this the RSSI Demo found!

Cheers.      

Glad to hear you got it working! Thanks for reporting the issues you had to solve

Cheers
