Good morning, so I’m in a bit of a rush as I need to fit one of my ABS-02s cubecell to a cow tracker which is heading off on Friday. I’m having trouble with lowpower state using to much battery power.
Searching I discovered a thread that the GPS can be powered off using GPIO14, supposedly.
Doesn’t seem to be working!

The code im using to control the pin.
#define pin GPIO14
// setup
pinMode(pin, OUTPUT_PULLUP);
digitalWrite(pin, HIGH); //Off
digitalWrite(pin, LOW);
If I then try a use the GPS with the pin pulled HIGH is still works.
Do I need to end and restart the serial commination to the GPS?
Does ending that before going into lowpower mode save power? and restarting on wake?
Cheers, James
