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...
Suddenly DFU OTA fails most of the time while trying to update units with code & "not secure" bootloader that has been working for years. The FW upload stops at 2% to 8% but...
Hi,
This is my first time designing RF section for BLE using nRF54l15, and i was wondering if you guys can give me some feedback on hardware design. I chose a Johanson 2450AT42B100...
Hi,
I am trying to optimize my nrf52840 application for power consumption. If I run simple loop using nrf5 SDK i get ~1.2mA. However with similiar code on Zephyr: I get...
Hi,
I am developing a small beacon application using the nRF 52805 device, and the intent is that it will send advertising packets at a slow rate, to indicate to a partner...
I'm working on implementing arithmetic operations using the PKA engine on the nrf52840 in Rust, following the CRYPTOCELL — Arm TrustZone CryptoCell 310 datasheet. While I...
Hello all,
I have been working on the implementation of the PKA engine on CC310, and have been encountering some unexpected behaviours when using the modular multiplication...
Hi,Nordic team
I am programming with nrf52833,ncs v2.9.0,base on peripheral_hids_keyboards and central_hids.
On central I call bt_hogp_rep_write_wo_rsp can only send one...
I'm currently developing a project using the Audio NRF5340 to communicate over BLE. All the modifications I made to the Audio DK app work in VScode with SDK 2.9.0, but recently...
Trying to work through using the FLPR for a virtual peripheral. I can infer things like the VTIM sets counter 0 and 1 to automatically buffer data in/out via the VIO setup...
Hi,
I adapted the nus_client from the Nordic Connect SDK v2.7.0. I changed the UUID and some function names, but in general the code stays the same. I can subscribe one...
Hi,
What is the static current of nRF52832-QFAA at the temperature of 60℃ and 25℃ (when ADC ADC ,RTC are turned on, an IO port is opened for interruption)? I tested it at...
Hi,
i have some code thats based off of the uart_async_adapter.c example code. I' m getting a `usage fault` which i've traced to uart_irq_handler. it happens when i try...
Dear Nordic Semiconductor Support Team,
I am using the nRF52840 for distance measurement and have observed multiple distance-related parameters in my output, including RSSI...
Hi,
I would like to test a websocket connect over NB-IOT with the nRF9151DK. I started with the https_client example to do an https handshake with the server and then add...
