First time here? Check out the Tour!
Hi! I am currently doing my project on BLE beacons. I am using nordic's nrf51822 and waveshare ble400. I am using a blackmagic probe instead of jlink to program it using Arduino IDE. I want to use sandeep's ... (more)
i would like to connect two Redbearlabs Nano v2 just with eachother. The central one connects just to the peripheral, but the peripheral is still open for every device. So i want to use direct advertising and give the ... (more)
I need 3.3V on my Arduino connector, I need to use the Arduino shield. I am measuring 3V on VDD line. According user guide, if I cut SB38 , VDD will be disconnected, I assume this means that I will ... (more)
What is the easiest way to use Arduino libraries into nrf52 projects in Keil on C? Arduino has a lot minus : bad ide, not support debug mode, not optimize code size. But it has one huge plus, you can use ... (more)
I'm in the process of migrating from arduino to SES IDE(For more practicality and functionality now what I'm trying to achieve is saving time by not having to rewrite all arduino libraries I'm currently using ... (more)
Hi, I try to mount some I2C devices at Arduino Primo but I can not get any results. I tried an I2C LCD that did not return any error but did not display any text. When I scan I2C devices ... (more)
I had purchased the Red Bear Labs "Micro" board to develop code using their MK20 USB Dongle and Arduino.
If I "hack" the programming cable to emulate the "Micro" daughter board to match the pins used on the PC2006 Beacon ... (more)
I'm develope some sensor with arduino primo, which use nrf52832 as a primary mcu. I want to measure battery voltage level,and i find some example like: https://devzone.nordicsemi.com/questi...
but i confused with which SDK ... (more)

i am able to use nrf24l01 to communicate raspberry pi with arduino, but the problem is the timing. I found it takes > 20 ms to send a very simple string ... (more)
I was pointed to st7565LCD.c for this question before, but SDK 13 does not seem to have that example. It would be really helpful if I can get spi_read() and spi_write() functions as welll. thanks.
Am beginner of nRF51822, please suggest programming tool and tutorial links.
Dear Nordic Team,
Thanks for supporting.
I have a nRF51822 Board (PCA10028) and Also i have arduino code for reabear from (https://github.com/RedBearLab/nRF5182... )this link. It was generated hex file also.
I am try to burn this ... (more)
by using Arduino mini pro 3.3v
I am planing to measure the temperature for the first five minutes, if the temp is over 40 degrees the device will send to Android app and flashy red led(sperated led).
if ... (more)
I am using arduino to sample sensor and it sends out the value to the digital pin. I want to read this digital value using nrf51dk. Is there any example using digital read? I will be using uart service ... (more)
I am trying to implement a biometric group telemetry system for my gym and experimentation.
In the past I used a nRF24AP2 module and an ARDUINO PRO MINI 3.3V 8MHz and a custom library wrote by me. ARDUINO ... (more)
I am working on my hardware product having nRF-51422 chipset. I just came to know from forum post that nRF-52 chips will get arduino IDE support as standalone. I want to upgrade to nRF-52 series, If i will use ... (more)
i made this project to try to create RSC service on arduino
unfortunately the server starts but i'm not able to let the speed to be set.. could someone help me?
I am very familiar with the arduino side but the BLE is brand new to me. I was wondering if I can use P0.00 and P0.01 to talk to the arduino and if its possible how exactly I ... (more)
Hi, could anyone please help me as I currently using nrf51822-arduino-library in a nrf51822 chip and I couldn't call the interrupt function : wakeUp(). Current I'm connect the external interrupt pin to nrf51822 pin : P0_1 or arduino pin : A0 ... (more)
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. The receiver should receive temperature values ... (more)
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 and iOS applications. There is sample UART code for ... (more)
I have been trying to combine the UART and hID Keyboard examples into a single application. I want to use the HID part to send specific keystrokes using buttons on my Arduino. I want to use the UART ... (more)
I am looking for cheapest (up to few hundred USD) and simplest Arduino basic solution to track real-time RFID tags distance (also direction if possible) without additional readers or antennas. Current setup: 1 reader and 3 tags with ability to ... (more)
Hi I would like to know if it is possible to to run the Nrf905 chips on 5v logic level without damaging the chip ? i see many people playing with arduino and these chips but would just like to confirm the setup.
