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, I designed custom board using nRF52832 and SHT20 ambient temperature sensor. Temperature sensor not detected using example sdk TWI scanner. SCL and SDA pins correctly...
Hello,
For our product, we wish to store a custom post-production name (essentially a serial number) in the UICR registers of the nRF52840. We understand that this can...
I am using a code similar to App_uart_C from SDK17.02 - central sending data over uart to another peripheral.
After 30-60 sec, the operation stops probably due to an error...
Dear Fellow developers
I am developing an application where I need several nrf51 USB dongles (S120) attached to a PC, and I need a way to distinguish one dongle from another...
I am integrating PWM into my project which uses SDK_15.2.0.
My config.sh contains:
and I have included nrfx_pwm.c.
Compiling the project I get this error:

The project I'm working on is running off of a CR2032 battery. I want to measure the battery voltage while the radio is transmitting to determine when the battery dips down...
Hello,
I am using "pdm sensor" with "NRF 52832". we have PDM Drivers provided by the NRF . I just want to understand how we can connect the data and clock pin with nrf ...
Dear Members,
I create a loop inside main.c using code example ant_shared channel,
it's merged with ant_plus hrm_rx, but on forever loop, it stopped on 6 loops, it's...
Hello!
A frequent question in the forum is how to enable logging messages.
My question is exactly the opposite: I experience many NRF_LOG_INFO messages from Nordic library...
I'm having some issues with a design I'm developing using the ISP1807 bluetooth SOC (contains nRF52840). Every time I apply power to my device I have to manually reset the...
Dear Members,
How can I display multiple ANT channel ?
It looks like one channel is occupying all the resource (HRM)
How can I manage the time slice between channel...
Hi,
We are building our synthetic sensors using nRF52840 for smart buildings. In some areas we are using it with BLE only, other areas we use it with BLE mesh. When we want...
Hi,
Hope you are well.
I want to send the saadc data with ble to my pc. I used the below code. I am getting the data in the right format but i am loosing some data in...
I am experience some for me strange behavior with UART0 on a nrf52832. Let me explain:
First I initialize the UART using:
APP_UART_FIFO_INIT(...)
with parameters setup...
