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,
In our existing project, it has a Bootloader and MBR, but no SoftDevice. Transport is UART for DFU.
I need to port the Bootloader to work on another project that uses...
We are wondering how nrf9160 modem decides which band to use when there are multiple bands available (LTE CAT NB) and there isn't any apllied band lock from the software side...
I've been working with the nRF52840 WLCSP package for a month or two now, and in many ways it's a great compact chip. However, as my projects require more and more pins, I...
Hi guys, Im now developing my custom board with nRF52832 based on the reference schematic below. And using Keil uvision for a programming my board.
The final objective of...
Hi
I have two custom build boards based on nRF9160-SICA. Both boards also have a nrf52840 running application code. The nr91's are running identical firmware (slightly modified...
Dear.
Now Im testing the nRF24L01 to develop a module.
Using this, I want to know the receive power.
nRF24L01 has a registef to use similar function. Register...
Hi,
I'm trying to write firmware for the nrf52840 that reads from a sensor and then sends data to a PC over BLE. Ultimately, I need the BLE link to achieve ~ 1.1 Mbps throughput...
Hi all,
I observe a connection supervision timeout (HMI error code 0x08) in my Nordic firmware with certain Android smartphones (controller).
Additional info regarding...
Hi. I'm just wondering if Nordic Semi engineers have done any tests with standard beacons (any particular beacon interval and test condition) application and compared current...
Hi teams,
We made BLE mesh custom boards based on nRF52833.
These nodes are configured to send broadcast messages for every 10 seconds.
Currently, these boards uses...
Hi Sir,
We would like to use the Radio test to do the basick TX/RX test in SDK 15.2
We use the nRF52840-DK for test and follow the CLI document .
1. We use two board...
Baud rate 460800, error code NRFX_ERROR_INTERNAL(1) occurred when the serial port received data。
I want to know how to avoid this problem, the current transfer rate is less...
Hi
We need the recv() be blocking until the full amount of requested data can be returned or the operation was timeout, how to achieve this?
I tried flag MSG_WAITALL but...
Hi. Can anyone think of a way to use the nRF52832 (probably Timer) to detect approximately 125KHz-150KHz variable square wave down to about a 1Hz resolution? I'd like to detect...
