Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
Hi
How to find out which BLE version is supported for a given Nordic SDK + SoftDevice.
From which version of Nordic SDK is compliant to Bluetooth 4.2 ?
Hello,
This subject is partly a conclusion and partly a question I would like confirmed.
Our scenario is that we would like to fetch flash logs over BLE, but not really...
“EBSHSN” is reset by the RESET pin when the control CPU shifts to sleep mode when the terminal device is stopped. When measuring the current consumption in this state, about...
Hi, nordic.
I've been developing a product with ws2812B.
As I know, ws2812B is needed around 5V to work well.
And I measured voltages on 52 DK board.
VDD pin has...
Hi,
I designed a customer board and defined my own board header file, which is pretty much copied from pca10056.h. One question I encountered is I somehow couldn't toggle...
Hi,
I try to develop a fix that should allow me to use the pc-ble-driver to receive scan responses (see https://devzone.nordicsemi.com/f/nordic-q-a/50082/pc-ble-driver-no...
I have one doubt that why there is elements or models in Bluetooth, it can be simple as sending messages and then translate them into useful work, in this single element and...
hello,
inorder to send a string over ble from a slave to master or master to slave what is to be done??
is there any function for us to pass the string??
I want to understand the meaning of "standard drive, low frequency" GPIO pins. The datasheet mentions to use these pins for frequencies below 10 KHz. Does this limitation...
HI
I have to sending a sequence of 768(96 bytes) bits to program a custom piece of hardware on a single data line. Initially the line is low for 500ns and then each bit...
Hello. I'm testing ESB examples with nrf52832. Want to understand which max speed I can reach with that protocol? Some devzone info says that 1.8mbps can be reached. But among...
The assumption that `fds_record_find` returns records for NOT CHANGING file_id and record_key in the same order they have been written IS WRONG. The documentation sub-section...
Hello everyone,
we are developing a bluetooth application based on the relay example included in SDK 14.0.0. We have already developed our own services and characteristics...
We are working on a combination 52840/9160 board, and after having much success with most software components, have run into a roadblock with the more complex Bluetooth samples...
I am trying to create a custom board file in the ncs/zepher/boards directory for our nRF9160.
If I copy the nrf9160_pca10090 directory to a new nam eg. nrf9160_newboard...
