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...
I will start doing a custom PCB (1.3cm diameter) with a nordic BLE, any recommendations about the components needed and design?. I need to use mbed programing tools, any experience...
Hi,
After training on a PCA10028, i want to develop on my personal board.
I use keil but i saw a problem.
The libraries are all in folders of folders in the sdk folder...
I don't know why I didn't notice this blurb in the reference manual sooner. In pretty much all peripheral sections (such as SPI), you have this warning:
Therefore, the...
When loading the ble_app_uart_s130_pca10028.hex file (Windows 10)
from nRF5_SDK_11.0.0_89a8197/examples/ble_peripheral/ble_app_uart/hex using nRFgo Studio - Program Application...
Hi,
I programmed the NRF51-dk to take ADC samples and transmit those values at 8 bit resolution. Now I want to send a 10 bit resolution value over BLE UART, but I believe...
Hi everyone,
In my low power application , I use PORT EVENT to detect the interrupts of my two pins.
when I use only one pin interrupt, it's working well .
But with two...
Dear All,
We are implementing 8 Pheripheral Nodes and one central node with S110 and S120 respectively.
We have our custom board with us we are able to connect the pheripheral...
Hi
I want to run RAM retention sample example with sd_app_evt_wait(void) .is it possible?
is it require soft device to load first?
I have included S110 soft device of...
Hello Nordic team,
are there documentation about the MTTF (Mean Time To Failure) Value of the NRF51822?
For more details please see the EN 13849-1. We need this information...
Hi
I want to operate nrf51 in various power modes available like low power mode, constant latency mode system idle mode and so on.my questions are as follows:
