Hi,
Thanks for the help. I have run the proximity detection application in nRF52832 nordic thingy. Initially the LED was blinking in the thingy board but when I switched OFF and ON the power button the LED was OFF. I have programmed the sample from Nordic Infocenter for nRF52832 DK. Please help me out if I need to flash the firmware again or any alternative to get my thingy board power ON again. For your reference I have checked the battery status.
