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 am developing packet exchange process for betwween nRF51822 BLE to My MCU.
I modify to use nordic demo project.
It is place C:\Keil\ARM\Device\Nordic\nrf51822\Board\pca10001...
Hi,
I created firmware to nRF51822 Development Kit but I have a problem with connection. PCA10004 board is programmed to advertising packets whole the time and measure battery...
Hi ,
We are using nordic nrf51822 custom board.
In our we are not using any external oscillator.
so here is my configuration for advertisement in ble_proximity

Hello,
I have posted a question regarding the HID template code for the nrf8001. I would like to say that the progress from your help has helped immensely.
Currently...
I am having an interesting issue trying to send packets. Only a very small number are being received (~1 per second even when transmitting one after another), and they are...
I want to use a UICR for device serial number. Correct me if I am wrong but it is my understanding that a UICR cannot be changed programmatically like onboard flash can. So...
I'm using the UART to talk to a GSM modem. It has hardware flow control and supports a baud rate of 115200. I'm using app_uart_fifo.c, not app_uart.c. I'm using the SoftDevice...
Hi,
Does Nordic Semiconductor provide any resources (codes, macros, documents) for work with IAR or Keil's simulator to fully simulate nRF51822's peripherals?
Thanks...
Hi,
I do:
err_code = ble_bondmngr_bonded_centrals_delete();
APP_ERROR_CHECK(err_code);
till now all is ok.
But when I do:
err_code = ble_bondmngr_whitelist_get...
Hi,
I need to delete all centrals using ble_bondmngr_bonded_centrals_delete ble_bondmngr.c function. It is working but it is not cleaning the whitelist.
So, when I do...
In the example of hid_mouse, ble device will bond master when disconnect event happen.
I try to add this two codes to Implement my idea.
