Can't read serial from MT3339

by sflo344 on Fri Jan 25, 2013 6:45 pm

Hi,

I am using the Ultimate GPS breakout board with an Arduino Micro and can't get to read serial either using SoftwareSerial or direct serial using the examples provided.

http://learn.adafruit.com/adafruit-ulti ... ter-wiring

I get to write to serial and get output on the Serial monitor but when connecting the GPS to RX, TX as mentionned, with empty setup() and loop(), I get nothing with 9600 bauds.

The red led flashes every second as there is no fix, even after an hour.

Is there any other way to troubleshoot?

I gave it another try. Hooked it up as direct connect (http://learn.adafruit.com/adafruit-ulti ... ter-wiring) and uploaded the 'blank' sketch. Can't get any output from the GPS' serial.

You're help is appreciated.

TX/RX is reversed. Switch the TX and RX on the Micro and you should be in business.
