Sniffing with ANTWareII

2023-02-16T17:14:29+00:00

Hi,

I am using ANTWare II v4.1 and a USB1 ANT+ dongle. Is there a reason why the "Open Scan Mode" button is grayed out? Or what I need to do in order to enable it? I am trying to sniff the air between two ANT+ devices and am able to see the broadcast packets but the dongle is ACK'ing the burst packets I am trying to sniff.

Thanks.

Non-garmin usb stick

Hi there,

There is various non-Garmin ANT USB stick for general usage. Do those devices could be used with ANTWareII for development purposes. Couldn't find any Garmin Ant USB stick in the local market for a short time.

Standard data format of Ant+ device

2021-07-20T20:10:31+00:00

I am working on a firmware for an Ant+ USB dongle I built for testing based on the nRF52840 SoC, and was able to collect data from a connected fitness (bike), and forwarded that to my PC through USB protocol. However, the format is something of my own, not what SimulAnt+ and other applications would comprehend.

Assuming there is a some standard format to follow, is there any source code or protocol specification documents that can help me format the data properly to talk to SimulANT+? I want to communicate with Zwift, and I am assuming that it follows the same standard, no?

Sending from master to slave on the same device

2021-03-12T11:10:15+00:00

Hello,

For technical reasons about our chip, we need to implement some kind of "keepalive" service on a ANT+ device. So I had the idea of using 2 channels, one for transmitting and one for receiving messages on the same device.

BUT, using ANTWare II or SimulANT+ i'm not able to receive any message from the same device.

e.g:
On ANTWare II:
- Device A: Channel 0 - Master - Device Type 125 - Device Number 33 - Auto-Open
(Starts broadcasting 00-00-00-00-00-00-00-00)
-Device A: Channel 1 - Slave - Device Type 125 - Device Number 33- Auto-Open
(EVENT_RX_SEARCH_TIMEOUT... EVENT_CHANNEL_CLOSED)

Is this possible or is a software filtered issue?

Thanks,

ANTWarell not pairing with bike trainer

2021-01-21T09:31:48+00:00

I can connect with my bike trainer (Tacx Flow Smart) using ANTWarell if I input the relevant channel ID data but I cannot get a connection when using pairing and with channel ID data all set to 0. Can anyone tell me what the problem might be?

ANT burst retries

2021-01-12T16:15:24+00:00

Hello,

I have query about ANT burst mode, I want to confirm that which mode of ANT BURST uses automatic retries and which does not. Here is a document which states ANT BURST uses automatic retires but it's not clear if this is classic and advanced mode of burst.

https://www.thisisant.com/resources/an04-burst-transfers/

Page 3/7:
In addition to the increased throughput advantage, ANT Burst mode uses acknowledged messages with automatic retries to ensure successful data transfer while maintaining a simple interface to the application MCU. As an exception however, single packet bursts are handled identically to an acknowledged message, and are not retried.

Thanks.

Help with Power Meter RX

2020-11-17T02:36:14+00:00

Hi. All I want to do is view a log of RX messages from my power meter on my PC. It would appear this can be done with AntWare II. I attempted to use the Power Profile PDF and enter in the info necessary.

EVENT_RX_SEARCH_TIMEOUT_0x01
:: 40, 07-01-01
EVENT_CHANNEL_CLOSED_0x07
:: 40, 07-01-07

Is what I'm seeing. What Channel do I set up the Slave on? Any ideas?

I would have thought this would have been a trivial task.

Unable to get EVENT_TX logs in Master mode

2020-05-29T09:49:22+00:00

Hi.

Aim: I need to broadcast some dummy data over ANT.

I'm using a CYCPLUS USB dongle to transmit ANT packets in master mode (no receiver setup for receiving). But I'm unable to see any EVENT_TX logs generated from ANTWare II (v.4.1) as part of the transmission. This seems like very basic, am I missing something?. Thanks.

The steps I have done to setup is:
Connected CYCPLUS USB (auto driver install happened)
Opened ANTWare II and I could see the device listed on 'Available devices'
Assigned as Master in Channel assignment.
Auto-Open.

Note: It's always SlaveSearch~ID:0,0,0 in ANTWare II, no matter the mode (even if Master).

Set Bike Power

2020-05-27T13:54:16+00:00

Using this ressource : https://github.com/dhague/vpower/tree/acab2ec78e15851ba5a3a9176ff2177f02ed36fc (PowerMEterTx.py) I am trying to set the power with my Rpi on my Power Meter Bike using Ant+. I think I am doing something wrong with the python and there is probably something I do not get.

If I want to set the power to 300W I need to send this command in hex : 31-FF-FF-FF-FF-FF-B4-04 if I refere to the doc.

Also Power Meter is device type 11. So using the code below I'd like to send my Hex code, but there is something I do not get with


update

function. It looks like the payload is used to set the 8 values of my hex code, but I do not get how to change the code to set this 8 values. (31-FF-, etc...).If someone could enlighten me it would be great.

Someone know how to send this command using python code ?

Thanks
