Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
Hello, I am looking for the way I can use PWM to control duty cycle of connection. I am really novice and my understanding about programming and Bluetooth protocol is really...
I'd like to use the pin sense function as the power switch of my NRF51822 device. That is to say, after the very first power cycle (reset or battery change), the device goes...
Hi everyone,
I am trying to learn nrf51822 using Keil,
I need a very simple program to learn such as:

Hi,
I am trying to get the PWM example ( github.com/.../nrf51-pwm-library) to work with a Softdevice (S110) that advertises.
There have been several Questions on the...
hi hakon, you told me to do " Try using the variable, for instance by setting "rx_info.rssi = rx_info.rssi;" in the callback and see if that helps." in the question i have...
I'm trying to perform communication between my device and iOS and I ran into some problems. For tests I'm using iPod touch 5 with nRF Toolbox and LightBlue apps and nRF51822...
Hi, for some reason ADC_IRQHandler is never called for me.
It's fairly simple and a direct copy of the battery sensor example, so not sure what happened here.
is there...
I've been using Master Emulator API 2.1.3 in Visual Studio 2010 Express, and have spotted a fix I may need in 2.1.5 so I've switched to using the 2.1.7 API. However, I've...

Hello,
I'm using: nRF51422-QFAA E00 and SDK - nRF51 5.2.0
My problem with ADC is that I stucked when waiting for event - end of conversion.
I used the code from Nordic...
Hi everybody!
I've plugged my NRF51422 as a slave on a STM32 through a SPI bus. I would like to be able to send to the NRF an unknown amount of data. I also need to read...
Error happened in pstorage_init() when sd_flash_page_erase(), return value 0xF.
I use S120 examples. So I guess maybe my device don't support S120 ?
