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...

Greetings,
My name is Maria, I’m working in an application with the nRF51822DK to communicate via Bluetooth to the USB dongle (PCA10000) and send data between them. In the...
Hi,
I'm seeing a lot of this issue with iPad mini (1 gen), iOS 8.1.3.
Many times I start the bluetooth app, the connection just drops while doing service discovery,...
Hi,
I am trying to run event based UART. here is my code snippet:
void uart_callback(app_uart_evt_t *p_app_uart_event)
{
uint8_t rxbyte;
switch(p_app_uart_event->evt_type...
I'm getting started trying to use the device firmware update (DFU) feature of an nRF51822. I'm using soft-device (bluetooth abstraction) version S110-SD-v7.1.0 , and SDK ...
When I try to update the application on the nRF51422 chip over DFU, I have trouble with the bootloader.
I use the nRF Toolbox app to do the firmware update. I can select...
Hi guys, this may be a lame newbie question, but I was unable to add a driver to my uVision project. For instance, I've opened the ble_app_template and now I want to include...
In the reference designs, the inductors in the antenna circuit are simply referred to as "High frequency chip inductors". Do you have any example manufacturers part numbers...
I'm testing my nRF51822 Bluetooth Smart Beacon Kit (pca20006). I've successfully uploaded ble_app_beacon_bcs code example to my beacon via Master Control Panel Android app...

Hi All,
I tried to use the nRF51422 device UART RXTO events using nrf51 SDK v6.1.
I set the NRF_UART0->INTENSET in app_uart_init() as following:
// Enable UART interrupt...
Hi, I have just managed to successfully read ADC values and send as a service but they are in uint8 format. Is there an easy way to convert this to decimal within my adc handler...
Is there provision for a serialization application processor to control GPIO on a nRF51822 used in serial connectivity mode? Can the nRF51822 be used as an I/O expander?
Hi,
I want to simultaneously read the value from 3 analog pins. For this, do I create just one adc_init function and handler functions or do I need to create multiple initializing...
Connections to my peripheral device are generally very short. I don't really need to have my device request a connection parameters update.
Does this mean that I can safely...
