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...
We want to build a network of many nodes (nrf52 boards) distributed in the apartments, that are connected via BLE over 6lowpan, of course using a border router for communication...

How to develop nrf31512, is it same to the nrf24le1? why i use the same firmware download to the Nrf24le1, it can run normally, but download to the nrf31512 , it can't work...
Hi All,
In my application I have two analog inputs coming from two different sources that I have to sample using one SAADC present inside NRF52. As far as I know, NRF52...
Hi,
I'm using nRF5 SDK V12.0, I found a strange problem. That is the UART can send data to PC, but it cann't receive data from PC. However, this problem just arise on some...
Hi,
I need a bit of help to fully understand how ADC works on nRF52832.
I am using a Thermistor sensor like the following to measure temperature:
Epoxy Thermistor...
We would like to use the PPK for automating some of our tests. Is there any documentation on how to drive the PPK over RTT? If push really comes to shove, we can always read...
BLE UART This is a problem that I have discovered while checking
the cause of the connection frequently due to communication error.
It is normal... In the nRF52832,...
Hi,
I added following code in saadc example code to set GPIO pin high/low and monitor it in the terminal. The pull up looks ok, but when I set it to low, the reading never...
We created our own PCB for the NRF52 with a Johanson chip antenna but no matter what we do, we can't get a signal from the Antenna, not even a weak one to show up on the spectrum...
Hello,
I duplicated the project example "nrf51-micro-esb-master" under "proprietary_rf" and got it up and running. I now need to incorporate some timer functionality.

Hi. I'm using nRF51822AC, SDK12.2.0, S130 v2.0.1 as central.
As I've tested by using
err_code = sd_ble_gap_address_get(p_addr);
APP_ERROR_CHECK(err_code);
App returns...
hi
i am using nrf51822. i used the radio tranceiver example and it works well. I am planning to advertise the received packets so that the range can also be increased and...
