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.

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, New user here, I develop using Kicad and it has an antenna based on the Ti SWRA117D design, which is 2.4GHz. Can I confirm I only need two components (as per reference...
Hello,
I am using the SPIM module to communicate the NRF52832 with a sensor, every time it generates an interrupt - which is generated with a frequency of 25Hz. For the...
Hi expert,
I'm working for my project that make a controller for drone, and that i need nus for as my service so i can exchange the data (send order via rx from smartphone...
Hi I'm trying to integrate the iBeacon and Eddystone protocol together. For this I'm using the timeslot to advertise the packets simultaneously. I have successfully integrated...
Hi,
I currently did many test with BLE our new devices, and i am stuck on this probleme since days. The goal of those test are to have internal too for validation process...
I am working on my first nRF52832 design utilizing a 4 layer PCB. I have been reviewing the different antenna options for this device and have some questions about the PCB...
Hi Everyone I am trying to get a hold of the nrf9160 SDK which is based on zephyr. Here is what i would like to know 1. There is a file named zephyr.dts which has all the...
Hey guys, I've been trying to do a range test with 2x PCA10056 dev kits. I believe I've set everything up correctly and cannot achieve more than 300-400 meters before the...
If we input 5V DC supply to Vin 3-5V P20, the Bluetooth programming failed at start. But if we input 3.3V DC supply to P21, the Bluetooth programming passed. Is this Vin 3...
Hi, I tested "Simple_coap_client" and "simple_coap_server" on NRF52840 using Threading SDK.
It seems that the route is decided by the leader, can I specify the route?
...
I am making a simple breakout board for the nRF52833 (I'm using Fanstel's BM833 module). This is what my board is looking like. There's a ground plain on the top and the bottom...
I'm trying to send data from a NUCLEO F401RE board with the nRF 52840 DK using UART. Then have the data to be sent to my phone via Bluetooth. I'm starting from the ble_app_uart...
Hi Devzone:
I have a question that may be common for companies distributing hardware containing nrf52840 chips.
I have figured out how to use nrfutil to generate Bootloader...
Hi there,
I connected my nRF5340 PDK to an external target - which was unluckily defective.
Since the external board had its own power supply, there was now either an...
