• First get your IrDA USB adapter working (info http://wiki.rene.ee/doku.php?id=parnu_elamine:smarthome.irda)
• you may need to install some software:

sudo apt-get install libxml2
sudo apt-get install libxml2-dev
sudo apt-get install "libusb-0.1-4

• Download code and unpack it: https://code.google.com/p/polarhrm/

• open configuration: vi src/cli/polarhrm_config.h
• and add the location where you want the downloaded HRM files be stored: static const char *MYPATH = “/home/rene/Downloads/”;

• NB! Theres a bug in code that must be fixed (or you won't be able to download multilple exercises from the watch
• open this file: vi src/libpolarhrm/S625X_watch/S625X.cpp
• make row 108 look like this: session→createFilename(workingDir);

• compile your code:

cd src
./configure
make

• now should everything be up and running!

• set your watch into the “CONNECT” mode to start listening for your PC
• place the IrDA dongle in line with the watches IR tranceiver
• cd /home/rene/Dropbox/code/opensource_projects/polarhrm/src
• run polarhrm to download files (might take a while): ./polarhrm s625x
• now you should see the *.hrm and *.dump files in the directory you specified in the config earlier
• to delete downloaded files from watch goto FILE menu and locate the file to delete. Then press and hold down the light button (upper left) and you are asked permission to delete it. Procede with other files to be deleted.
• NB! If you get an error about not finding libpolarhrm.so.0, just cp the whole polarhrm directory to /tmp and do “make” again
