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...
Hello,
very simple question:
each time i click on the link from the following page, I get an ACCESS DENIED error

Hello all,
I have a question about the SAADC of nRF52832.
Now I use the SAADC to measure the some external sensor voltage and the internal VDD voltage.
The sensor connection...
Hello, Excuse me! I used the LFRC,the calibration interval of which is 8s, in my application on NRF52832. In order to measure the power consumption,I want to know the duartion...
Hi,
As well know, nRF52832 can use "16Mhz base-clock to output PWM signal, and it is very simple to create 4Mhz, 2Mhz, 1MHz signal output,
But, If I want to output a...
I'm trying to get a stripped down, simple LED blinking sample to work (like blinky) when building with GCC however main() is never called. I'm guessing I'm either using the...
I'm trying to take a project we had working with only an application, no softdevice or bootloader, and add a bootloader and softdevice, with the application still not requiring...
I am working on nrf5_SDK_for_Mesh_v2.2.0 with nRF5_SDK_15.0.0 and softdevice 6.0.0. I run code on PCA10040 dev boards. I am trying use a timer to send onoff message from a...
Hi Nordic,
Does FDS affect PPI ADC acquisition when writing data? The test found that once the FDS is written to the data, the ADC data returned by the PPI ADC is fixed...
Hello Nordic experts,
I am working with nRF5_SDK_15.2.0_9412b96 SDK.
In example nRF5_SDK_15.2.0_9412b96/examples/ble_peripheral/ble_app_hrs_freertos/main.c I have at line...
Hi all,
The setup that I am aiming for has a number of nodes, which will send the IMU data to a central base station. The communication is achieved using a bunch of nRF24L01...
I keep getting stuck in the TIMER1_IRQHandler function.
When I debug the code, I get to line 20 (exiting interrupt function scope) and then the assembly code hits a nop...
Hello!
I have developed a BLE HID (HOGP) device in Nordic SDK 15.0.0 starting from an example project: ble_app_hids_keyboard .
The HID device that I have developed however...
We have a setup where we want to measure the current consumption of a battery-powered device:
The batteries are soldered to the device, and cannot be removed.
We can...
