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...
So I've seen all similar issues people had where their program stuck on sd_softdevice_enable() due to the fact that ran on custom boards which didn't have external oscillators...
This are the contents of disassembly window on all optimisation levels. Program is stuck switching between two operations:
MOVS r0, r0
DCD 0xFFFFFFFF
I'm running...
We're moving our design from nRF51822 to nRF51422.
What's the difference between these IC from the point of view of PCB layout and antenna design? Are they interchangeable...

Hi,
Are there any available examples of Makefiles with JLink command integrated?
Example: "make flash" to flash the image or "make flash-softdevice" to flash the softdevice...
It's not really a question but a request to Nordic.
Could you change the #ifdef lines in gcc_startup_nrf51.s to .ifdef. So:
.ifdef __STACK_SIZE
.else
.endif
and...
Hi,
How do I determine the application address? The one that is to be programmed to UICR.CLENR0.
I have SD S110 V7.1.0 but I didn't find this information in the release...
Hello,
I receive NRF_ERROR_INVALID_STATE error quite a few times because my own state handling is still a little buggy. I want to find all these errors. What would be the...
Hi all,
Please I want to make sure of something. In the s120 specification, it's written " Bluetooth low energy combined Central and Peripheral SoftDevice", and even in...
Hello,
I need to read the UID and later on also the RSSI value of devices (Handys) in range.
It should be reading the values automatically without the need of manual connecting...
The datasheets for the nRF24LU1P ansd nRF24LO1P have near identical example antenna driver designs which vary in the values for the inductors, etc
The LU1P datasheet is...
Hi,
I've combined twi_sw_master and DFU in my project based on nRF51822 Beacon v1.1.0. Now I can't connect to the beacon. The same project only with DFU or only with twi_sw_master...
Error is shown in the following figure.
I use nrf51822-DK(256k)
The exception of BLE_S110 works well.
Memory Is not enough when you add a BLE_S110
Is there any...
