I’m trying to build my own tracking deveice using the SODAQ One. In order to save energy, I wanted to make use of the Power Save Mode implemented in the U-Blox GPS receiver. After studying their datasheet for a while, I came across the following methods to wake up the receiver from it’s sleep:
The receiver can be woken up by generating an edge on one of the following pins:
• rising or falling edge on one of the EXTINT pins
• rising or falling edge on the RXD1 pin
• rising edge on NRESET pin
Now from my understanding of reading the SODAQ One schematics, none of these pins are connected on the board. So I came to the conclusion that it’s impossible to use the Power Save Mode.
Am I correct with this assumption or is there something I missed?
Any help would be greatly appreciated
