/*
* try to put a UBlox into binary mode. This is in two parts.
*
* First we send a ubx binary message that enables the NAV_SOL message
* at rate 1. Then we send a NMEA message to set the baud rate to our
* desired rate. The reason for doing the NMEA message second is if we
* send it first the second message will be ignored for a baud rate
* change.
* The reason we need the NAV_SOL rate message at all is some uBlox
* modules are configured with all ubx binary messages off, which
* would mean we would never detect it.
* running a uBlox at less than 38400 will lead to packet
* corruption, as we can't receive the packets in the 200ms
* window for 5Hz fixes. The NMEA startup message should force
* the uBlox into 230400 no matter what rate it is configured
* for.
