ANT Forum

Hello,

I am trying to ramp up knowledge on ANT+ leading into development of a new software application. To that goal I am trying to learn to use Simulant tool. I have 2 USB Devices and have tested each by inserting into PC and loading HeartRate Display and connecting to physical HeartRate Sensor. Independantly each device is working.

Now my test is to use 1 USB device as Heart Rate Display and the other as a Heart Rate Sensor. The sensor starts broadcasting and the display connects.however I keep getting the following errors in the ANT+ Verification display:
440432875 : Fail: Default Page (data page 0x00) received with reserved byte 1 set incorrectly.
440432875 : Fail: Default Page (data page 0x00) received with reserved byte 2 set incorrectly.
440432875 : Fail: Default Page (data page 0x00) received with reserved byte 3 set incorrectly.

These keep repeating and the messages look like empty data:
440432875 : Rx: [00][00][00][00][00][00][00][00]

Maybe I need to read more about the message protocol but I thought the sensors in Simulant would work when loaded.

What am I doing wrong here.

Thanks      

Sorry, should have provided them the first time. these are the logs from the same test as the dispay      

When I ran the tests I started logging before clicking the "Turn On" button on each device so everything should have been there, I did not see anything else that was not in the log. I was using the Heart Rate Sensor not the legacy one and the Heart Rate Display

I just ran the test again to confirm, there are no additional events in the sensor display. I did try clicking some of the Send comman buttons on the display and it indicates that messages were sent but I dont see any messages in the sensor.      

Both devices are listed as Dev0:USB2 and Dev1:USB2

I have tried the devices connected directly to 2 USB ports on the laptop and with both devices in a USB hub, with the same results. I also have tried starting Simulant with 1 device connected and then running another instance of Simulant after connecting the second device.

     

Version 2.3.0.0
Managed Library Version AMO 2.4.0.0
Unmanaged Wrapper Version AOA 2.901
FIT Profile Version 16.73      

Do you have any additional thoughts on this? I really need to get a simulation environment up and running. Is there any other software that could be used to simulate a sensor? I would suggest that I write something myself using the .NET sdk, but as I am a newbie and in the learning stages myself that would be a risky step.      

Today I tried running some of the demos from the PC SDK DEMO_HR_RECEIVER and DEMO_HR_TRANSMITTER and they also seem to have a problem. When I transmit a HR of 75, the receiver just shows zeros for the data. However when I try the ANT_NETDll_Demom things do seem to work okay (See image). I am using 2 Cycleplus USB dongles.      

Ian,

Thank you for checking on this, I was wondering if my USB devices are to blame. I am currently using a devices from CycPlus, purchased on Amazon. The best I can tell for the part number is X0010DL7K5 US U2
This is the link to the product: https://www.amazon.com/gp/product/B079217ZGV/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

I am very willing to purchase a device which is known to be comopatible with Simulant.

     

Thank you, I just ordered 4 units, will test and get back to you after they arrive      

Ian,

The Garmin USB devices came in today and worked immediatley. Thank you so much for your help and I appologize that I took so much time due to the type of device I purchased. I intentionally did not buy the cheapest USB device to try and avoid such a situation but being totally new to this I did not know.

I can now move forward with the development of our application.

Thanks again,

Thomas
