The DW1000 Power Calculator java application seems to be having issues when it has always worked in the past. It runs but fails to calculate any values.
If I run it from a command line I get the error:
java.io.IOException: Server returned HTTP response code: 403 for URL: https://www.decawave.com//TWRCalculator/TWR_power_calculator.xlsx
From memory 403 is access forbidden.
And then when I click on calculate I get a null pointer exception on a call to ExcelInterface.writeCell
So it looks like the java application is just a front end to a spreadsheet that is hosted on the decawave servers and for some reason the permissions on that excel sheet have been changed recently so you can’t read it.
The odd thing is that I can directly download that spreadsheet.
