Hello,

here is the link to the documentation

http://www.u-blox.com/images/downloads/Product_Docs/u-bloxM8_ReceiverDescriptionProtocolSpec_(UBX-13003221)_Public.pdf

GSV is on page 84.

And the mode switch is described in

 "21.11.13.4 Extended NMEA protocol configuration V1" on page 141

That is useful information.  Can you point me at a copy of the u-blox spec
that describes this field?

Clearly the ubx driver is going to need some work to support the m8.
