We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

Hi,
I'm trying to get S110 softdevice (v8.0.0) working with RIOT. I had some issues (I couldn't initialize TIMER1 or TIMER2 until softdevice is setup & enabled) but I think...
Hi!I'm having some problems in adding a new library to my project (sdk 11.0.0,s130), I want to add ble_nus.h. I follow this instructions " devzone.nordicsemi.com/.../" but...
I want to implement static passkey based bonding, using the nrf51822 on both sides[Central is not a Mobile phone].My sw for peripheral side is working with a mobile device...
Hi,
I have this following picture on keil when i am doing the first TUTORIAL (in tutorial party), the example works but i don't understand why keil display this (red cross...
Hi
For a university project I'm looking to create a small Bluetooth based sensor network. For this I was hoping to get your recommended products to work with. I suspect...
Can anybody please tell that what are the specs for BLE l2cap layer? In BLE 4.2 core specification it describes l2cap for BR/EDR/LE but i am not able to understand that which...
Hello Nordic Community,
I need to know how to import my PCB design from Eagle to CST Studio to simulate it and I need to know if the simulation step will be useful to enhance...
Hi all, i am experimenting on the example "ble_app_beacon" on my smart beacon kit, but i have two questions about it (though they are pretty general):
When a connection...
Hi Experts，
I use TIMER_1 and PPI to driver a 'H' style bridge for our motor. Unexpected system reset will happen if I trigger the 'H' bridge PWM with ble connected. It...
Hi,
I run the code of the radio_test example in a VisualGDB project. When I start it with a debugger connected, VisualGDB informs me that a ARM semihosting system call...
Hi, is their any brief explanation for nrf5-sdk-for-eddystone project firmware newly released by nordic. I go through the project but it is very hard to understand can any...
We have an use case that we may need to support up to ,say 500 sensor nodes and it may be added or removed dynamically. And we should collect all sensor data within 3 seconds...
Hi all:
Based the descriptions in data sheet, the GPIO9 and 10 are set to NFC antenna pins by default.
And I cannot control these 2 pin correctly by configuring the pins...
I want to use NRF51822 to advertise is door close/open. No need bidirectional data sending.
Only one way from NRF sensor to mobile phone app.
Actually I have only two different...
