I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi, I used the sample code "Master Emulator->2.1.7.8226->Example code->nRFUart"
to develop a new project, and encounter some questions...

Hello,
How many RX buffers are in S110 SoftDevice? I know there are 6 TX buffers (so you can send 6 packets per Connection Interval).
How is it on receiving?
Is it e...
My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
Hi,
My android Proximity application fails on service discovery only for the very first time it connects with the devices(nrf51822 evaluation kit with sdk 5.2.0). Actually...
Hello,
I made a PWM with the TIMER2 of my nRF51822 (with the SoftDevice) and was working fine, till I read that I should not use the "NRF_PPI" functions and use the "sd_ppi_XXX...
I've got an nRF51822 development kit that I'm trying to get started on. I've gone to Kiel and downloaded uVision 4 (mdk472_a). I install it with all default settings and it...
Hi,
I add UART support using IRQ on the "ant_hrm_tx" example code.
and I'm sending packet of 4 bytes that contains: Delimiter,HeartRate,Battery,Delimiter
the frame...
Hi, I am trying to test my UART using some simple loopback test, and I have noticed that the service discovery command of BLE will occupy the CPU a quite long time. I am just...
I was unaware that the 'manufacturer data' in the advertising packets is limited to less than a full payload. However, whenever I set it to >6 the program "crashes".

When I use keil to download the software to the chip, there are two questions:
like attached.
2.NRFGO CAN'T SEE J-LINK LITE CORTEXM BOARD
Is there any way to solve...
We have recently moved to a new PCB which puts the nRF8001 on the layout instead of plugging into a nRF2741 development module. The nRF8001 connects to a TI Cortex-M4 Tiva...
Hi, we would like to create a kind of game using 2.4Ghz emitters . The 2.4Ghz USB Dongle emits and the mobile phone detects the frequency + embed unique ID/code so we confirm...
To be more detailed:
One of my ADC pins will be connected to another device that could be providing a voltage of about 3V, but through a 100 kohm resistor. (actually it...
Dear Nordic Developer Zone,
Since I have implemented a timer with interrupt in my application, the debug mode if the Keil IDE stops working when I try to restart the code...
Hello, I'm trying to develop with the nRF51822 Eval kit and GCC and Eclipse. I've been getting some strange behavior and errors lately. I'm not really sure how to describe...
I'm a green hand HW Engineer.
I'm trying to compile, program, and run The Heart rate monitor demo though following the step in nRF51822_DK_User_Guide_v1.0.pdf .

Hi Nordic devzone,
For the nRF51822 device, I would like to know if there is any internal pull-up/pulldown resistor on SWDIO and on SWDCLK (although a 12 K-ohm pulldown...
