Checksum requirement - NormOnASUS - 11.12.2014
I am ubable to convert my lisr of waypoints becase they don't have checksums. My reading of the specs says they are optional.

Hi Norm,
according to the official specification, the checksum is optional for most data sentences, but is compulsory for RMA, RMB, and RMC (among others).
The most pragmatic approach is, when you send me your data and I'll check how it could be read.

Thanks for the response. Here are a few lines from a nmea file of mine

Do you have just WPL sentences without a checksum? Or are other sentences affected, too?

There are only WPL sentences.

Hi NormOnASUS,
I've uploaded a new prerelease of RouteConverter which should be able to read the WPL sentences without checksums. Please test and report if it's working.

I installed a new version of Route Importer from Google play stores and tried to import a nmea file an get this error
Error:'$GPWPL,3018.000,S,15309.000,E,Coffs Harbor (Sidney)' does not match.

I'm confused... Route Importer? Google Play Store?
$GPWPL,3018.000,S,15309.000,E,Coffs Harbor (Sidney) is accepted by the new RouteConverter prerelease.

You have to explore whether there are any log files giving more detailed information.
