Or is there any LCD you could suggest that doesn't need that much code? Simple numeric 2rows would be enough. Want to use it with the nRF51-DK to display some measured valued...
I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hello. Can I get a literature to the nRF51 series?
I need a full abstraction of the nRF51, like a book or other information, it's structure schematic of build-in modules...

Hi!
I wonder how can I measure the delays, latency, errors and connection speeds. I'm using nrf samples for bluetooth peripheral_uart connect it with nrf connect app. I...
I have a SPI Master and a SPI Slave. The Master will randomly pull data over SPI from the Slave. The slave will randomly generate events that result in data to be sent to...
I am using SDK version 17.0.2. The example code uses SPI.
The following changes have been made to the pin settings.
Questions
1. Pin behavior is strange.

Hello, Support team.
Our boards do SPI communication to read sensor data.
Basically It works well. I checked that It operates more than 5 hours.
But only one board...
Hi,
I have the following initialization for advertising:
The name consists of an acronym od three letters and a underscore e,g, XXX_ and a six digit ID. Like XXX_12E124...
Hi,
Is it possible to add four pairs of resistors between the debug signal lines and the connector as shown in the figure below.
Would such a connection not impair the...
The Google Fast Pair Service has recently been included in a number of Bluetooth peripherals (Headphones, fitness trackers, etc.) and has been getting rave reviews.
Has...
I am able to download simple blinky program on my custom board. It is working fine. Custom board is interfaced with nRF52-DK through P19. I am using embedded studio as IDE...
Hi, on nRF5340 I want to capture accurate timing of external events. I need a kind of real-time capture module to read the time period of a pulse train generated by a rotating...
Have a few questions about ble_app_uart example.
From the way I see it, it sets uart_event_handle as the callback, and every time there's an "event" that takes place...
Hello All,
Method 1: I am writing a test application to read the ADC data at a specific intervals(10 samples for every 5ms interval for every 50sec). I am using blocking...
Hi,
We are implementing a synchronous light flashing of multiple devices, so:
1) Can we get a millisecond level (< 10ms) time synchronization by parsing the Link Layer...
Hi, all
I added a scanning module to the example 'ble_app_uart.c', so each one works well.
What I want to do is advertising and connect at the same time while connected...
What is the best practise for multichannel SAADC conversion in ultra low power devices? For example I have to measured 4 channel in interval 250ms. Below what I try:
