I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
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...
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...
I purchased a pair of FTDI cables, and I can't seem to get them to work.
Unsure if the pinout is standard but here is the mapping of the cables provided:
Red wire： 5V...
I am using the N548 with the S310 soft device. I have set up the device for asynchronous communication via the UART. I can send ANT+ commands via the UART and I get valid...
