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...
I am trying to implement UART service which should act as both central and peripheral at a time.
So, I started implementing ble_uart peripheral service into the central...
Hi,
I'm testing the nrfutil tool for DFU in windows but it seems that when running nrfutil keys --gen-key private_key.txt I get " no such option: --gen-key" , using nrfutil...
Hello,
I have been developing firmware on a custom nRF51 board.
Upon testing firmware that involved BLE advertising,scanning, UART communication over BLE and FDS, i observed...
hi i have made gate opener for my farm, i am using MPU9250 and nrf52 to measure how much degree its open i am putting my MPU in cycle mode to wake up and take data, but it...
Hello
I would like to point out that I have no knowledge of electronics.
I am in the advanced stages of building a project on the basis of Adafruit feather nRF52832, The...
I am trying to test the fatfs example (SDK14) using the 10056 DK.
I do nothing modification and it results in...

I realize I am like the hundredth person to have this problem but all the solutions I have found don't seem to work.
I am trying to add a simple header file to the nordic...
I am new to Nordic, I am able to compile and run examples on nRF52-DK.
I know there are examples are done for us but how I can develop my own project which use multiple...
I just replaced SDK 14.0 with the shiny new SDK 14.1 in my project. My project uses components from the SDK, but I don't use the exact same structure. Once again, it won't...
My Environment
