Hi
I write an application code to read and write the data from EEPROM, by using twi_hw_master.c.
its working fine. i able to read the data from eeprom what i have written...
Hi,
Let's say that you have a processor and a nRF51822 as a coprocessor. The first processor sends commands to the nRF51822 to drive it (init the stack, init the services...
Hi all
I can debug some example project with breakpoints likes blinky_example .
But in ble_app_hrs project, how can I set breakpoints and watch variable value with Keil...
Is there any limitation for number of advertised services?

Here I´m again,
Maybe sound a little bit silly but I´m not able to find a way or a solution to make simply a Characteristic with more than one attribute. Something similar...
Folks,
Is there a document that describes the events generated by the S110 Soft Device and their interpretation? (Note: they're not listed in the S110 SoftDevice Spec v1...
Hi,
This is loosely related to the other question I asked a few weeks ago ( devzone.nordicsemi.com/.../two-interrupt-events-on-timer0) but this time I want to have two timers...

Dear Nordic Devloper Zone,
I am facing a problem with RTC timer.
Here is a scenario :
I have an IOS application which is able to set the current time on the nRF51822...
As I understand it, like most modern PHYs the central and the peripheral are exchanging symbols to maintain link integrity and adjust Tx power to maximize battery life.
...
From what I am reading in the S110 spec, this service is supported but not adopted (i.e. example code. Is this correct? Has anyone implemented a navigation and location service...
