Connection question

[david-4444]

Thanks for sharing these tools. I'm having problems getting going.
I've installed everything but I get this error. 'no polar USB device connected' although I can find it in the folder /dev/ttyACM0 ?
It's a Polar Vantage M.

david@david-OptiPlex-790 ~/polar $ ./polar_ftp -d/dev/ttyACM0
? serial ? found, but couldn't open serial device on /dev/ttyACM0: EACCES
Please specify the device to use with the -d option.
No Polar USB device detected.

I tried again, this was the output
david@david-OptiPlex-790 ~/polar $ ./polar_ftp -d/dev/ttyACM0 DIR /
Polar Vantage M serial 849D7322 found, but couldn't open serial device on /dev/ttyACM0: EACCES
Please specify the device to use with the -d option.
No Polar USB device detected.
Any ideas gratefully received.

Hi David,

It seems that you just need to grant yourself access to /dev/ttyACME0 (eg, with sudo chown or sudo chmod).

Cheers

Thanks Cédric, The SYNC works well now. I'm really pleased I can now connect my watch to Linux without having to send all my data via Polar flow.
In case others have the same problem, this is what I did to give myself access.
Opened the directory /dev in terminal
changed the owner of ttyACM0 to me, and changed the read write permissions to rw-

david@david-OptiPlex-790 /dev $ chown david:david ttyACM0
david@david-OptiPlex-790 /dev $ chmod 660 ttyACM0

When I list the files in the /dev directory this is what ttyACM0 looks like now.
crw-rw---- 1 david david 166, 0 Apr 25 10:08 ttyACM0

Then using the polar_ftp ruby command I get:
david@david-OptiPlex-790 ~/polar $ ./polar_ftp -d/dev/ttyACM0 DIR /
Connected to Polar Vantage M serial 849D7322

I have a couple of questions. I hope you don't mind, I'm a bit of a newby to Linux.

1. I can only get the polar_ftp command to work using ./ before the command when I'm in the directory containing the Ruby script. It doesn't work in the terminal like other commands. Have I done something wrong in the install ?
   david@david-OptiPlex-790 ~ $ polar_ftp DIR /
   polar_ftp: command not found
2. I would really like to be able to convert multiple files, e.g. take all the training sessions as .gpx files.
   I have managed to get polar_trainng2gpx to convert 1 file at a time.
   But is it possible to search all the folders and convert multiple?

$ ./polar_training2gpx /home/david/polar/polarwatchfiles/U/0/20210424/E/185520 ~/polar/gpx_files/20210424run.gpx
Converting Polar training session in '/home/david/polar/polarwatchfiles/U/0/20210424/E/185520' to Garmin GPX format as '/home/david/polar/gpx_files/20210424run.gpx'...
Done

Many thanks, David

1. this is because the directory in which you installed the tools is not in the search path ($PATH). You may add something like PATH=$PATH:/path/to/polar/directory in your profile (usually ~/.profile or ~/.bashrc)
2. I use another script that builds on top of those tools to convert all training sessions to TCX (unless already converted), something quick 'n dirty like this:

#!/bin/sh
POLAR_DIR=/path/to/polar
IN_DIR=~/Polar/<device ID>
OUT_DIR=~/Trainings

$POLAR_DIR/polar_ftp SYNC

mkdir -p "$OUT_DIR"
for dir in $(find "$IN_DIR/U/0" -type d | grep -e '/E/[0-9]\+$'); do
    out=$(echo $dir | sed -n 's/.*\/\([0-9]\+\)\/E\/\([0-9]\+\)$/\1-\2-polar.tcx/p')
    outfile="$OUT_DIR/$out"
    if [ -n "$out" -a ! -f "$outfile" ]; then
        $POLAR_DIR/polar_training2tcx "$dir" "$outfile"
    fi
done

Adapt as suitable to you. BTW, if you only need this script, you may not need to change your $PATH -- just create a ~/bin directory (if it's not there yet) and place this script in that directory (and make it executable with chmod +x). Depending on your Linux distribution, ~/bin may already be in $PATH (you may have to logout & login again -- check your ~/.profile & co).

Cheers

I have similar error on windows platform:

C:\Ruby31\bin>ruby.exe C:\GitHub\polar\polar_ftp DIR /
? serial ? found, but couldn't open serial device on /dev/ttyACM0: ERROR_PATH_NOT_FOUND
Please specify the device to use with the -d option.
No Polar USB device detected.

Where and how can I find the Vantage V path (value for -d) in Windows platform?

Hi @maiko29,

On Windows, I believe you should try --dev=//./COM3.

If it's not connected on COM3, try COM4 or check the list of connected devices in Device Manager (check Show Hidden Devices and expand Ports (COM & LPT)).
