Hi,
I have 2 pins with PULL_UP in sense mode and when i use sd_power_system_off() i measure 25mA current, which is higher than when my system is on (around 10mA)!!
How...
We are using an nRF8001 with bonding. We are trying to figure out how big the dynamic data is that we need to store (since we are used a fixed-size storage in flash memory...
I just received my Beacon Kit and need a programmer/debugger but money is tight. These are the options I'm looking at:

I wrote an application that works using an Enhanced Shockburst-compatible protocol (because I need it so), using the RADIO interface.
What happens if a packet with an address...
Hi U guys
First I’m pretty new I use of bluetooth low energy, so bear with me.
It is pretty simple, I need to send a temperature each 10 sec. or whenever it has changed...
Hello. The nRF51822 Series Reference Manual says on page 38, "The SWDCLK pin

The desire is timeout after 60sec...
Hi,
We are trying to use the over-the-air bootloader in our application.
Our problem is the bootloader seems to require one first over-the-air download before it allows...
Which pins are mapped as ADC inputs for the NRF51822? I've pored over the documentation, but I can't seem to find which ADC pins (AIN0 to AIN7) correspond to which GPIO pins...
Hi
My aim is to be able to update the application code OTA in a 128kb chip (version nRF51822 QFABB0). First, I want to use the nordic original code to discard any other...
