we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard
Firt I connect to Android device and keep one whitelist.pp_addrs and one whitelist...
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 .

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...
