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 are trying to get an mBed-compiled hex file uploaded to production hardware but it is throwing the error "failed to read hex file".
The code is compiled for the nRF51...
Hello
I want to connect nRF51822 (on a readbearlab ble nano) to arduino micro which uses 5V logic on a 32U4 IC. I know I can use an external logic level shift, but I need...
In table 32 on page 25 of the NRF51 Reference Manual, there are a bunch of registers with the description "Reserved for Nordic firmware design" or "Reserved or Nordic hardware...
Dear nordic.
I am testing with nRF51822, and have some question about hardware stability check.
nRF51822 have Clock Monitor Unit (Clock fault detector)?
Is WDT same...

Hi, we're working on a project that involves constant streaming of gyroscope and accelerometer data from an NRF51822 based module to a Linux machine.
What we've been working...
I am using the ble_uart_app on the dev kit with the nrf52. SDK version 11.0.0. How do I get the bsp_event_handler to get fired on a button release and button push event and...
Hi, I'm using stlink + openocd to flash and debug and it works fine.
But I want to measure the current consumption with nrf51822 debug interface off
Is there an equivalent...
I have a high-speed signal which I would like to sample with the nrf51's ADC. The signal is periodic (80kHz) and is from a low-impedance source (op amp buffer). I don't need...
