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

In the nRF52 reference design, not using the DC-DC converter would result in higher power consumption. By how much? Any documentation regarding the details. Thanks
Hi all,
I am new in nRF51822. Today I am doing experiment using GPIO and radio transmission.
I wrote a very simple code as below:
int main(void)
{
init_clock();...
Hi, I've got a serious problem in my project. Some of its features require hard timings. The usage time of these features is longer than the single timeslot and I must be...
Hello guys, I'm doing a hobby project and can't seem to get it working. Aim of the project is to transmit temperature values from a DS18B20 using an Arduino Uno and NRF24l01...
I'm experimenting problems with a nRF51822 custom board. Recently I managed to run the blinky sample project. Now I'm trying to test a BLE project, but I'm having problems...
Hey All,
I am currently trying to have a Analog Signal come in through P0.05 which then gets converted via the onboard ADC and send out a Service Characteristic. I am using...
Hi,
I am using your NRF24L01P-R7 part .Can you please specify its maximum distance upto which it can detect other TAG in open area when there is no wind at normal atmospheric...
I have a question about PXP profile. Could I use the nrF52 (S132) Nordic's PXP example to dynamic change TX power when I have bonded or connected Android phone device ? I...
I try to implement a BLE vendor service that has some characteristics. When I bonded the nRF devive (vendor service already download to device) with my Android phone and then...
Hello All,
I have modifies the Spi Master code to communicate with an ADXL345 Accelerometer. I set up my powermode and the percesion in the setup phase. However, when I send...
Hello, Nordic Team.
In my program, I have to change the value of the characteristic before start. I write:

Hello,
I want to make my Arduino coupled with the nrf8001 advertising a simple data (an integer). There should also be a possibility for dynamically changing the advertising...
I have a Jayconsystems breakout board for the nrf8002 bluetooth chip. Nothing is connected to the breakout board and the chip is unprogrammed. My current meter reads 6.0 mA...
The nRF8001 Product Spec says,
