Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
i made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
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 .
First...
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...
Is it possible through the API/Softdevice to do one of the following:
read out the current advertising data structure, change a the manufacturing data field, and...
Hi,
I am planning to use modules with nRF8002 in an indoor positioning application.
The mobile devices that are to be located are continuously scanning for BLE devices and...
Hi, got an interesting problem, this is on a custom board with nRF51822 QFAB that we are bringing up. The radio test (not using softdevice) works ok and produces strong transmit...
Hi
Could you provide the power current in System on Active, System on Sleep, and System OFF for nRFready Desktop2 keyboard and mouse? nRF51 was programmed Desktop 2 v1.0...
Hello,
I am working on the factory test mode and I want to add a carrier test, is there a function from the S110 softdevice library that I could use?
Thank you for your...
Hi,
I set up eclipse according to n-AN29 and imported several of the example projects. The blinky_example project described in the nRF51822 dev kit user's guide works perfectly...
Hi, I have been trying to maximize the baud rate of my uart module, I am using the app_uart layer to control the uart and I have noticed that in your implementation of HCI...
I have an ultra low power application that needs to broadcast it's proximity on a 1sec interval. However, about 75% of the day I would like the device to be powered down and...
