Connect adafruit ultimate GPS - Spaek - 2018-09-29 Hello, I am maling an openplotter setup for a small sailboat. I am using a raspberry pi with various sensors, and everything was working easily and fine. I have a vk172 USB GPS wich is working fine for testing, but I want an external antenna as well. I bought a ultimate GPS, du cannot get it to work. I have tried two different ttl adapters. I get some info in the serial menu in openplotter, but no baud rate or info. The gps LED is flashing and showing a fix. Anyone have some suggestions? I would really appreciate it! Regards RE: Connect adafruit ultimate GPS - Spaek - 2018-10-03 Can I provide some more info to get some replies here? What would you need to know? RE: Connect adafruit ultimate GPS - jim321 - 2018-10-03 raspberry pi version various sensors ? version of openplotter how its wired i don't think you have to use a ttl adapter Connecting the GPS module Wiring it up is pretty simple: Raspberry Pi - 5v -> GPS Module - VIN Raspberry Pi - GND -> GPS Module - GND Raspberry Pi - Tx -> GPS Module - Rx Raspberry Pi - Rx -> GPS Module - Tx https://www.stuffaboutcode.com/2013/09/raspberry-pi-gps-setup-and-python.html Enable the UART can be changed if needed i have one of these it works and has a usb connection and external antenna + a lot cheaper https://www.ebay.com/itm/183425731611?ViewItem=&item=183425731611 https://www.ebay.com/itm/3M-28dB-LNA-Gain-1575-42MHz-Male-SMA-Male-GPS-Active-Antenna-Stronger-Singal-NEW/142813296573?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 RE: Connect adafruit ultimate GPS - Spaek - 2018-10-04 I just got a signal now, but I can not get the GPS connection to show in opencpn now. I get no connections there, but the vk172 is really easy to get working. Is this a known problem? I will try to take some screenshots tomorrow. |
