Valid Location (JSR179) without an NMEA String ?

[Tiger79]

Hi,
I've been using JSR179 API's to obtain, well, locations
To make it compatible with my software i decided to use the getExtraInfo("application/X-jsr179-location-nmea") method to obtain the NMEA string from a Valid Location...

It worked untill I tried to change the powerUsage to Low...

after that the received Locations still are compliant to the isValid() method but it wont return me a getExtraInfo("application/X-jsr179-location-nmea") String ! Instead it will return null...

So anyone who had the same problem or knows why I wont be able to obtain the NMEA string when power usage has been changed in the used criteria ?

After some trying it works if I set the Power Requirements to Medium.. so now the question is : how much more (or less) does the Medium value use compared to the NO_REQUIREMENT value ? Cant find any info about it on the API documentation
