I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
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...
Hi,
I need to reduce the consumption of the peripheral_uart sample on a nrf5340dk, I use nRF Connect SDK V1.5.0.
At the beginning, I measured with an ampere meter 591uA...
When I program my external board via the nrf52dk the programming is much slower then when I program the nrf52 chip on the devboard. Is this normal behaviour and if not how...
Hi,
I'm evaluating a wireless microphone scenario, using 52's I2S and external ADC chip to sample sound signal, and than wirelessly transmitting it to another 52 for receiving...
Hi,
sorry if this is a trivial issue, but I've been strugling with this for a while, so I decided to just ask for help.
For context, I'm trying to create an application...
I have devices within an same group that bind with same app key, all are working normal together. But I want one device to be unbind and bind with another app key(out of the...
Hi everyone,
Hope you are doing well!
I am using BLE and FDS simutinuously but since they share the same interrupt priority (SD_EVT_IRQn = 4), fds events will be blocked...
I am currently running some tests on the Legacy DFU protocol and notice that even valid firmware images are unable to be transmitted. My setup is as follows:
Peripheral...
Hello,
As shown in the question. I am testing the ncs bootloader b0 and mcuboot, but I don't know it's ok or not.

I am...
Hi
I have a strange question to ask for your help.In my program, I define and use a large number of global variables. However, when I define a global variable again and...
Our application frequently changes the channel table when we find interference in multiple channels. So changing channels frequently (because of high interference) causes...
Hi,
I'm evaluating BLE power consumption with a PCA10040 nRF52DK and a PPK, I cut SB9 and did nothing else with DK.
No peripheral is used in projects, Buttons or LEDs...
Hello
I've read several post about the problem regard the printf and float numbers, such as this ( https://devzone.nordicsemi.com/f/nordic-q-a/30535/nrf52-printf-float-in...
Dear sirs/madams
I am using SDK 17.0.2
Situation:
One Central unit (nRF52840) and one Peripheral unit (nRF52840) have established a connection (NUS service).
When...
I plan to buy some nRF5340 . I only see 1 chip image from the Nordic Official Website . However, when I clicked on " distributor ", I saw nRF5340 has many different part numbers...
Hi Nordic team,
I am trying to implement DFU over uart in nRF52832 using SDK 17.0.0. My device has nRF52832 and main MCU in it, and I would like to do DFU from main MCU...
