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...

I am using nRF52 DK kit which has SWD connector for booting External device but it is booting only nRF52 Board not the external board
please can any one suggest me the right...
Hello,
I am designing a custom PCB with NRF52832 IC. According to datsheet, required specification of inductor L1 are:3.9nH, 0402 package, 5% and a High-frequecy chip inductor...
Hello,
I did some power measurement on the nrf52 DK with the Nordic profiler kit and the result was way more than what we could expect from a nrf52 (about 1 mA). Even in...
I am working on the ANT connectivity for a product we've developed, called RunScribe [a shoe-worn running sensor], and am seeing some issues on Fenix 5 watches with our ANT...
Hi,
I'm trying to implement run the ESB and the BLE concurently using the timeslot API.
I started from this example : devzone.nordicsemi.com/.../
The problem is this example...
Hi,
I'm quite a beginner to this whole nrf52832 world and I'm trying to read some data from a flex sensor wired in series with another resistor connected to VCC now I understand...
In brief our problem with rfx2411n is that rfx begins to draw 200ma current without any reason. Rfx is powered down, powered from 3,0v. And suddenly something happens and...
I have a device that runs with nRF51 chip with the NRF UART Service (NUS).
I have a Raspberry Pi 3 and I want them to communicate.
The device requires an authentication...
My question is related to peripheral device only. I have implemented an auto connection interval negotiation algorithm which works as expected and negotiates connection interval...
Hi! I am building an android app for my project. I am using Proximity , UART and DFU from nrfToolbox app. I have 3 buttons on my home screen dedicated for each of them. I...
Hello sir,
I have completed PCB design of custom nRF52832 board. Can i use following component instead of recommended part No in reference design. I have also mentioned...
Hello ,
I would like to design a custom board with nrf52832 IC and CP2102 for communication with PC serially. Unfortunately nrf52832 doesnot have Rx/Tx pins for interfacing...
Hi community,
for our application (nrf52832 / SDK 12.2) we need to store data received via BLE. The received data is a 25 kB binary blob which by design will be chopped...
Hi,
i am checking NRF52840 for USB behaviour.
I'm using example usbd_cdc_acm.
But USB receiving stucks after few bytes (between 0 and 50) and does not receives nothing...
