- Do I need to use ioref? If so should this be connected to 5v or 3.3v out?
- I am powering the board (5v in) from the 5v pin on the Uno and gnd to gnd.
- TX1 and RX1 are connected to Uno pins 3 and 4 (RXPin = 4, TXPin = 3).
- UART1 baud rate is 38400.
Board is working fine and I get a flashing gps_fix led. I have check in U-center that UART1 is enabled for NMEA messages and in the text console I see all the NMEA sentences streaming.
What am I doing wrong?
