NRF51 current abrupt change

[liu]

hello, I uses NRF51822 to make a beacon with RTC. When it works initially, the churrent is small about 330uA，but after a few minutes it becomes 1.1mA and stable. I donn't konow why.

Check your error handler and if you're running in a debug mode. If there is some error occurring, maybe it's stuck in a while loop or restarting. That would probably use more than 1.1mA though, do you have a way to see the current over time on an oscilloscope? Seeing the current spikes for the beacon transmissions and what's happening after the few minutes will help you a lot in debugging.
