Hi,
I've created an application using the S110 experimental ANCS demo. I successfully implemented ANCS and then began to structure my application around it. At some point...
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 am using SDK 13.0 and tried to burn in fresh example code (Experimental NFC BLE Central Pairing Reference) to either PCA10040 and PCA10056. However both always shows...
I noticed that having the UART enabled on my application in a NRF52 (SD132, SDK 11.0.0) takes a lot of current consumption. If I completely disable any UART support on my...

As a follow up from devzone.nordicsemi.com/.../ , I am now trying to find out if I am getting all of the memory settings put together correctly. When I have them at higher...
I am using nrf51822, 16K RAM, 256K Flash.
From the movie , there is no way to secure my firmware for DFU. Is there any other way to secure my firmware?
Thank you
I know the many differences coming in bt5. Will the programming concepts be the same in the upcoming 5 version? IF my code is working with ble4.1 will it automatically work...
After a bunch of headache I was able to successfully program with the nRF51822 Development Kit without the nRFgo Starter Kit motherboard, here is how I did it.
Hardware...
I'm working on a design that incorporates an nRF52832 along with some sensors and drivers.
Up to this I've been sacrificing power consumption in prototypes by using LDOs...
Hello,
Is it possible to change SPI baud rate whenever we want?
For example:
The initial SPI baud rate is set to 4M. We want to change the baud rate to "2M" to get...
Hi,
This may be stupid, but I can't declare classes in my .h file in keil. I have arduino library for my I2C device, but keil; does not recognize when I declare classes...
