[Fwd: u-blox binary protocol boilerplate code]

[beren at kabelweb.at]

If you look at the ATR0635 datasheet directly from Atmel:

http://www.atmel.com/dyn/resources/prod_documents/doc4928.pdf

you'll read on page 14:
"RAW (RAW message support requires an additional license)"

U-blox (Atmel's software partner) only sells some of its products with RAW 
message support (notably the LEA-4T)
So even if it's a supported feature we can not really be sure if the firmware 
on the chip allows us access to the RAW messages :(

I guess we'll have to wait until somebody interested in this topic receives 
his/her own Freerunner...
