[SOLVED] SparkFun ZOE-M8Q GPS Chip with RPI 4

[Biglemon29]

Hi so I am trying to connect a SparkFun ZOE-M8Q GPS Chip to an RPI 4. I purchased the SparkFun Pi QWIIC hat and used it to connect to the GPS chip. On boot the chip's led turns red showing it is being properly powered. I followed the SparkFun guide for setting up the QWIIC hat. However, for their guide on the GPS chip, they only have one for Arduino. I tried following other GPS raspi tutorials online but none of them are working for me and my particular chip. Any advice on how I can properly configure this chip?

Assuming the the ZOE is like the Neo in that it is a 4 pin connection (+5, gnd, rx, tx) then it should be easy. See this link for configuring the serial port on the RPi https://spellfoundry.com/2016/05/29/configuring-gpio-serial-port-raspbian-jessie-including-pi-3-4/

Figure out which pins on the GPIO are the RX and TX. connect RX to TX and TX to RX. the terminal emulator minicom would work well. Search for how to configure the minicom software to work with the serial (hint /dev/ttyNN) and you should be fine.

Hi thank you so much for this! Do you know if then I would have to feed the data into gpsd?

I'm not familiar with gpsd. Some sort of daemon? Once you have it working with minocom, when you switch over to your application you would have your application access /dev/ttyNN
