Hi, I have just managed to successfully read ADC values and send as a service but they are in uint8 format. Is there an easy way to convert this to decimal within my adc handler...
Is there provision for a serialization application processor to control GPIO on a nRF51822 used in serial connectivity mode? Can the nRF51822 be used as an I/O expander?
Hi,
I want to simultaneously read the value from 3 analog pins. For this, do I create just one adc_init function and handler functions or do I need to create multiple initializing...
Connections to my peripheral device are generally very short. I don't really need to have my device request a connection parameters update.
Does this mean that I can safely...
I purchased a pair of FTDI cables, and I can't seem to get them to work.
Unsure if the pinout is standard but here is the mapping of the cables provided:

Hi there,
I am quite new to BLE.
I am about to buy a nRF51822 Bluetooth Smart Beacon Kit. But before that I would like to be sure if I am able to advertise battery level...
Hi,
We just recently received our (custom) board with the nrf51822.
To program and debug the nRF I use the pca10028 and the debug out header.
I wrote a very basic program...
