I am trying to build a battery device using the WiFire board.
I can only get the board sleep current down to 12 m amps minimum
The attached picture show a simple application (MPIDE) that wakes and sleeps every other second
I have tried all the recommended PIC32MZ sleep postings
I am not sure if the 12 m amps is due to the processor or something on the WiFire board
The WiFI chip is in hibernate mode
Just to be complete I also wrote a native MPLABX application to eliminate any Aurduio-Ness
The results we identical 12 m amps
I would appreciate any help or experience with this
FYI using 7.2 volt battery via the ext power

You should have all pins in Hz except Hibernate. Also you shouldn't have connected any peripheral (usb, microSD card), connect a jumper on pins 3 and 4 from J17 and also on pins 1 and 2 from J16. Also pins 1 and 2 from J16 can be used to measure the current.
