Here are some items needed...
Get the BBGW or BBG, respectively. Use the site for toptechboy.com and follow along. The groveGPS with the SIM28 should do the trick.
Oh and download the software, change it to suit your needs, and Bam!
As some of you know, Python is now Python3. So, w/ this update (some time ago), I have found this source is no longer a viable option for making the SIM28 Grove Connector GPS device work on the UART2 port on the BBG. But, if you know better, be my guest. TopTechBoy is still around doing things but I have been unable to make this source work so far...
Updates on the way!
