Hi Sir ,
I download hello_sensor app and use mobile power , supply power to BCM2073X KIT,
but BCM2073X KIT always after running for some time , the 2073x device will termination running.
Computer usb power and socket power normal running.
Maybe I need to change the switch SW4 an option?
Thanks you !
Take a look at Page 17 "Coin Cell Powered Application"
I believe this is what you are looking for as the board can only be powered by USB or a Coin Cell/Battery.
