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...
Hello everyone! I'm new to bluetooth mesh or even to C programming and i don't understand the following: I want to send messages over Bluetooth Mesh from an nRF52840 to another...
I tried to install the CDC driver using nordic_cdc_acm.inf in the DSK15/examples/usb_drivers directory but the installation does not work and I get an error message when selecting...
Hi,
I tried several examples on nrf52840 dongle. Each one works well except usbd example. It hangs at the following code:
After investigation, the following simple...
Hi to all,
i am developing a device with nrf51822 and i want use it as a peripheral device, i want to write 4 packet per connection interval on noti char. i am ok with one...
Dear Nordic,
I just started with nrf52840 DK and my custom board. I derived my custom_board.h from nRF5_SDK_15.0.0_a53641a/components/boards/pca10056.h. I need to reroute...

Hello,
we want to evaluate the nRF52832 chip with a example project. This project has the following functions:
- low power
- system wakeup by RTC running with external...
Hello,
I do want to simulate the behaviour of several nrf51 chipsets that communicate over the air. Do you have any suggestion, how to start with this? The best would be...
Hello everyone! I am interested in running some simulations to test a series of algorithms for BLE on nrf52832. Is there any simulator which can easily simulate nrf52832?...
Hi All,
This may not be 100% nRF-related, but:
I have a set of algorithms that are written with Keil uVision 5 for nRF52840 using the CMSIS-DSP library. Now, I would need...
Hi,
recently i made the mesh works but now i need to add OTA.
i've found this tutorial. I'm still trying to generate the keys... every time i try i get some error from...
I can read from the driver using appropriate instructions. But i am not able to write to any of the registers. Please Help. I have attached the functions and datasheet.
