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.

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...
Hi Nordic,
Running a gdb session on nRF51, it is difficult to debug the code beyond the SoftDevice initialization. Then, I have to step through with (gdb)ni, but this is...
Hello everybody,
I used to my PCA10028 DK board with nRF51-DK-mbed-IF but I wanted to revert for nRF51-DK-J-Link-IF. According to the nRF51-DK - User Guide v1_0 documentation...
I have the code below initializing TIMER1 and and IRQ every 1ms. I call app_sched_event_put within the timer and I get a Hardfault.
Any hints on what is going on ?
Thanks...
I just bought a nRF5-DK and I couldn't get it to work flashing other nrf51822s. The modules I'm using are these wireless-tag.com/.../nrf51822-02.aspx
Here's literally what...
I have a PCA10001 setup and I am using SDK v9. I have opened the UART example in CrossStudio.
It compiles/builds and I am debugging with breakpoints.
My question is...
Hello,
I use the interface I2C to communicate to the Light Sensor, and also use a timer to read the value back every 1 sec now.
I'm wondering that can I use the interface...
I use nrf51822 by example ble_peripheral/ble_app_uart with with SoftDevice 8.1.0, at the same time, I use pwm driver library, But it does not work well, What I need to do...
Hello,
I have a problem with db_discovery_event_handler execution when having multiple S110 peripherials present when turning S120 central on. I have two different types...
I am seeing three things I don't understand in a modified ble_app_rscs codebase. I'm hopeful that someone else can recognize my symptoms and tell me what I'm doing wrong....
I've got a project that works perfectly on the PCA10028 DK. But the behavior is quite different when downloaded to my nRF51822 production target. My target is connected to...
Hi
I use nRF51822 of Gazell mode and RXF2401C(PA)
PA's TXEN has been pulled, what RXEX in there enbale and disable it?
(Host and Device must be)
Thank you!
Hi everyone,
My question is how much current it´s capable to sink an I/O pin configured as output ´0´ ?
In my case I have to discharge a capacitor throught an output...
I am using sd_power_system_off() to enter System Off. It is my understanding that all peripherals are off in System Off, but that GPIO configuration is retained. I have a...
I have the following code
