Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

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.

I am trying to establish communication using SPIM. when I checked the macro definition of NRFX_SPIM0_ENABLED it's present in apply_old_config.h. I am using nrfx_spim driver...
Hi,
I have two 52832 (both on SDK 14.2, S132 v5.1) talking to each other using a slightly modified UART service to support more than one connection.
I have this strange...
Hello,
yesterday I measured the current of our device and found out that it looks more as a square instead of spikes when no device was connected. Found out that when I...
In my code , i use P0.6, P0.8, P1.9 to control three RGB LED.
when I use nRF5_SDK_13.0.0-1.alpha, all is fine,
but when use nRF5_SDK_15.0.0_a53641a, the issure like below...
Hello,
I'm new to Nordic SDK and I would like to ask you for help with change of
GPIO IN_EVENT to GPIO PORT event implementation. The reason is we are using
revision <...
Hi,
I'm using nRF5 SDK v15.0 with S132 v6.0. I have two questions:
1. I use the ble_app_uart example. We want to use high UART baud rate, so I change it to 1M baud rate...
The project I am working on stores information in SRAM while it waits for the radio to get in range and transmit data.
I want to know if I can put items in SRAM buffer that...
I'm trying to learn the DFU process and how to include it in a project under development using SDK 15 and the nRF52 DK. I programmed the DK with the S132 Softdevice and the...
I'm having issues with slow directed advertising. I'm having a BLE peripheral where I want the device to advertise (direct) upon disconnects. I initialize the advertising...
My project goal is the following: To get data over USB and sending it to a computer using Bluetooth 5.
I've been looking around for a Bluetooth 5 dongle, but have not found...
I'm trying to sample ADC signal using 12 bit ADC resolution, but the digital signal doesn't match the original one seen in the Oscilloscope.
Here are my ADC configurations...
Hi i'm trying to using link with SDK14.2, and modified to the code with some init api,
when i used the MadgwickAHRS.c i modified, i got some trouble when i try to new a...
i'm have 2 device communicate byte UART protocol, one of them is NRF51822 and the other is some kind of MCU that i don't know clearly
NRF will send request to MCU then MCU...
Hello,
I'm usign nRF52832 with nRF5_SDK v15. I modified the example "ble_app_uart". I just remove the ble functions and added gpiote functions to wake up the MCU from sleep...
