I just hooked up my Sparkfun XA1110 module to my Teensy 4.1 board. When I connect the external antenna listed below (32db High Gain Cirocomm 5cm Active GPS Antenna Ceramic Antenna ), the unit can not get a fix. With the built in antenna, I get fixes but very periodic readings of zero satellites and poor positional accuracy. I’d also like to change the update rate of the unit but can’t find any documentation on how to do this. Any help on these questions is appreciated!
