Radio on - off example

From IARC 207 Wiki
Jump to navigation Jump to search

This code can be used with CR Basic compatible Campbell Scientific data loggers to power up & down the radio. To leave the radio on, in the Connect view, set the variable (user editable in this case) radioflag to true. When you are ready to leave the radio in the off state (winter for example) set the radioflag to false. Then, to further reduce power consumption you can direct loggernet to turn the radio off after the data retrieval is complete. To do this using the cora command library on linux:

echo "connect localhost; set-variable Radio_Accessible_Site Public commscomplete {} true; quit;" | /opt/CampbellSci/LoggerNet/cora_cmd

Or, from windows, put the following into a DOS batch file:

"c:\Program Files (x86)\Campbellsci\LoggerNet\cora_cmd.exe" < c:\CampbellSci\cora\radio_off.txt

radio_off.txt contains:

connect localhost;
set-variable Radio_Acessible_Site Public commscomplete {} true;
quit;


What follows is the code for the CR Basic Editor. A further modification would be to make the TimeIntoInterval() commands use variables for the on & off times.
