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
We are developing by connecting nRF52832 to SMT32f303cb's SPI interface.
SMT32f303cb operates as an SPI Master.
If the clock frequency of SPI Master is changed to...
Hi there,
I am using the FDS module to store some application data in flash. It is my understanding that every time the data is updated using fds_record_update, a different...
The nrf52832 defined the 250k mode in the specification, but it is Deprecated. We want use nrf52832 send data and Nrf24l01+(or nrf52832) receive data in our pruduct. We have...
In my situation, I want to use bluetooth to designed a piconet which has 1 master and up to 4 slave .
Each slave upload data 2KB/S ,and the max distance support is 10 m...

Hi,
I am evaluating the nRF52840-DK and wanted to add some debug code to the UART.
I have used the same libraries as the 'UART_PCA10056 (which works), but when the code...
Hi,
I'm using SDK5 V16 with the NRF52dk. I'm writing a SPI <-> BLE <-> USB I/O chain and am still kinda stumped by the SPI. All the examples work just fine, but when I look...
We seem to be having an issue on several Android devices, where reconnecting sometimes triggers an erroneous GATT_INSUF_AUTHORIZATION. This then causes Android to automatically...
Hello,
I am currently trying to get a project working that uses FDS, but I am having trouble getting the writing and updating working.
The peripherals in my project...
