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 made this project to try to create RSC service on arduino

HI,
I am reading LIS2DH accelerometer sensor data to nRF51822 MCU and displaying on hyper terminal. The LIS2DH sensor gives output in the
form of digital through SPI or...
Are there plans to create a nRF5x micro that has finer control over the RF power output? I'm currently using an nRF52, and the 4dBm steps are pushing the limits of our intended...
Hi. I'm using PCA10028, SDK10.0.0, S130.
Q1. I want UART to start or stop whenever I want. It's to save current consumption.
There is "uart_init()" for reference, but...
Hey folks,
i need to programm a nRF52 dev. kit to advertise data and receive advertisings sequentially, without connecting any device. It means that i need to advertise...
Hello everyone,
I have inherited a project from my coworker. It uses NRF51822 QFAAH0 , SDK 4.4.2 and S110 5.2.1 . My device is scheduled to: advertise, collect the data...
We are developinga product for a customer they want a secure connection and I'm trying to get my head around a certain aspect of the security:
If we choose to use a private...
The nrf905 has a CD (carrier detect) pin that is pulled high if the nrf905 detects another device communicating on the same channel. This can be used on the MCU for collision...
Hi,
In my application I am using Multiple App timers. Is there a way to prioritise these timers. Are there any draw backs in using multiple timers in "ble app".
Regards...
I want to set the resolvable private address ( RPA ) manually instead of letting softdevice do it. I went through documentation but I am not sure about it. I know that I can...
Hi
I am trying to put nrf52 device to system off mode, and wake up by button press.
If I do not enable the softdevice everything works fine, and button press wakes up...
Hi, I am trying to use the nRF52 to pass IMU information through BLE to a smartphone. We have a custom chip with the nRF52 and LSM9DS1 on the same board. I am able to program...
Hi!
Friday I can load the binary into PCA10040 (blinky example) ands works well. But today I load de binary but not works, nothing happen.
I'm used this example /Nordic...
It seems that I configured LFCLKSRC correctly, and advertising led flashes correctly.
Can I make any troubleshooting codes for Radio or Antenna?
Can I make some codes...
Hello,
Is it possible to erase only first N kB of internal flash memory before reprogramming nRF51 with JLink?
Lets say that I just want to erase first 64 kB of flash...
