Yes I did. Thats how I know its hard wired to be nmea @ 38400 and max performance. I tried shifting the resistors so that is should boot in ubx mode and eco power, but somehow it still goes to nmea @9600. I suspect the gpsd driver is forcing it to nmea 9600 by sending it a binary cfg-pm command. I just wish I knew how to do that!
