Hi :lol:
I would like to ask about Neo GPS starter kit programing.
I was able to get coordinat GPS when i'm using GPS Leadtek LR9548S. Here's my GPS Leadtek LR9548S code base on ATMega128 using codevisionAVR
All i know about Neo GPS starter kit was that Neo GPS is in SLEEP mode by default. And i already have make it wake up. And after it Wake Up, i try to catch NMEA output from it like this.
But there is no any coordinate received.
Please help me..
