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...
i made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
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...
I use NCS2.5.0，and I noticed that there are two files(bluetooth.h and scan.h) can help to set scan parameters.Is there any difference betwen these two files?Can I call the...
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...
