Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
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...
Well not my best title. But I hope you can follow this explanation:
I added RTT to my project to replace UART. It works so far. But there is a strange behaviour...

I am trying to do OTA DFU on nRF51-DK from a BLE dongle (CSR 4.0) and gatttool from BlueZ. The image is compiled from blinky_s110_pca10028 example ( blinky_s110_pca10028.hex...
Hi
I want to program the S120 softdevice over an mbed HRM1017 ([link text] that uses nrf51822. I can program only with CMSIS-DAP or drag and drop over the drive. I am using...
Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

Hello,
as I couldn't manage to get my SPI Measurement working flawlessly when called from inside a timer handler I tried to work around it by just setting a flag inside...
Hi,
I have a setup :
nRF51822_QFAC Chip Rev3
Softdevice: S110 V8.0.0
SDK: V8
Code hangs at sd_softdevice_enable(). Clock Source I am using is NRF_CLOCK_LFCLKSRC_XTAL_20_PPM...
Hello,
Has anyone managed to get the Nordic_UART software to pair in Windows 8.1?
The heartrate monitor software pairs fine. Using show bluetooth devices, I can see the...
Hi,
I have a PCA10028 board. When I connect it to a computer the LED LD5 doesn't turn on at all, and no new USB connection pops-up in my computer. But when I connect it...

Hi, this is kind of a basic question.
So please forgive me if this is too easy...
This picture is from nRF51822_PS_3.1.pdf.
Also these pictures is from the...
I am trying to use a differential antenna with the NRF51422 and I do not want to misunderstand the datasheet. It says that the optimum differential impedance at 2.4 GHz seen...
