I'm looking for a way to use the nordic uart service ( devzone.nordicsemi.com/.../ble_sdk_app_nus_eval.html) from Linux using the native Linux BLE Stack (BlueZ). My application...
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...
I'm working with a nrf51422/s110 dev kit on which I downloaded the Heart rate Monitoring sample project. On my PC, using a s130 dongle, I connect the device and wrote some...
Hello,
I would like to know about the possibility of programming the nrf51822 with a Keil ULINK-ME Debug Adapter (or, if necessary, Keil ULINKpro) instead of the recommended...
Our product has a legacy interface and for security reasons I want to allow users to disable or enable the BLE via this legacy interface.
My approach to this was to disable...
I've modified Nordic's "Nordic_Keyboard" sample to work with my custom board, just simple modifications to use custom_board.h rather than the default PC10028 configuration...
Hello,
I am having much fun with nrf52. I'd like to implement SPI read (few bytes) per GPIOTE event over PPI, the source is the GPIO event and the destination task is a...
Hi,

I'm trying to enable the use of some timer callback on the ble_app_template.
I've succefully created and started all the timers, but i...
I have a modem connected to some pins on an nRF51822 on a custom board. Two pins on the modem are active low. One is a reset pin, the other a VCC control. I want these pins...
Can the nRF51822 DEC2 pin (LDO output) be used as a 1.8V supply for low current use (say, <50uA)? Similarly, how about the 1.9V output of the buck converter (AVdd)? The current...
I'm wondering if the latest version (8.x) of S110 supports BLE 4.1's "Connection Parameter Request Procedure". This procedure is described in the BLE 4.2 spec Volume 6, Part...
I previously used Jlink to upload code to my nrf51. However, the new units I got are "locked" and I need to use nrfgoStudio to unlock and fully erase the chip.
Is there a...
Hi, I wrote a sample application to remotely control and led on nrf51822_xxaa module. in the application I was able to provide configuration to the characteristics as well...
Happened to try nRF master control panel service App.
It is a good tool.
But there probably something missing in "Scanner" screen.
I used heart rate example to do the test...
