Hi Tom,

the easiest way is to use a dynamic configuration. For example, these
two lines in your airframe makefile section:


will appropriately configure the GPS unit (the default baud rate is 9600 and here is set to 38400).

The other solution is to use the u-blox center tool through a tunnel uploaded in the tiny ("tunnel" target)

like everything but the GPS works.

     The wiki suggests setting the UART1 baud rate to 38,400, while
the airframe configuration files that use the Tiny seem to have it set
at 19,200.  I'm using a uBlox LEA-4P, and haven't run any special
configuration on the GPS unit itself.  Do I need to do that to use a
baud rate higher than 9600?  Alternatively, can I just set the
-DUART1-BAUD=9600 and have a working system?

Many thanks,
