Hi all,
I am new to Nordic semiconductor but I could be interessed by nRF9E5. To check if it could fit my requierement, I would like to know if it possible to configure...
Hi,
I am using ADC without external reference and no analog input in order to measure the battery level with a timer (code at the end).
I am also reading several ports...
Hi,
I'm programming the nRF51822 and save some user data into the FLASH by using pstorage_update . It works fine if I set system off mode, and wake it up. I can read back...
Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...

I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
I am planning to use the LPCOMP in conjunction with an external reference. I would like to just use a voltage divider to create the external reference.
Are there any impedance...
I recently received a nrf51822 mbed board.
I went with the mbed board over the EK because I figured it was more 'open', without realizing exactly what mbed was. I played...
I use the SPI slave function on 51422. When I send a byte(0x31) to 51422 SPI slave from master, 51422 will back a byte (0xAA - DEF byte) to master. Why?
I send 0x31 every...
Many Bluetooth library features are not yet available and so I would like to use a standard tool chain to compile sample programs and my own programs to run on the mkit.
Hi,
I am using the nRF51822 with an external 16MHz crystal. I was curious if there is any way to tune/calibrate the system clock that is derived from this crystal. The purpose...
Hi All,
I am novice in this nordic nrf 51822 programming. I wanted to know the best way to do the
following.
I have two different functionalities to be run on eval...
Hi All,

Hi
I found there is bonding managing routine in SDK HRM and Proximity examples.
bond_manager_init();
It means in these two case, after pairing with BTLE host, the...
My question is regarding the PPI channel groups. The documentation is extremely limited and leaves many questions.
My goal is to generate 3 PWM signals from a timer with...
If i understand tasks are for outputs and events are for inputs.
Wanted to know relationship between channel and the pin numbers. do they hold the relationship like...
Hello,
I am really confused on how to get a custom BLE service up and running. I have read through nAN-36, and compared the suggestions in that document to the HRS example...
In nRF51 reference manual v2.1 section 18.1.1, it mentioned that the RTC must be able to
run while the 16 MHz system clock (SysClk) source is OFF. 2 questions :
Q1: Since...
