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.

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 modified the code of ant_background_scanning_s212_pca10040 to make it works with s310 on nRF5144 xxaa.
The code works fine, but loose a lot of RX packets (more than 80...

Hi,
The samples for using list are BUFFER = 4, but it does not specify is that is the only size that works, and what value do you place on NRF_SPIM0->TXD.LIST
In my...
Here is a little background.
I have been developing a product based on the S130. I used the device manager from the S120 device since version 0.9 alpha. I was able to build...
Is there a mechanism to notify the application when a client reads from an attribute? For example, I have a large attribute buffer (100 bytes max) with a default MTU size...
Hi,
We are implementing a device where we need to use BLE and PWM. For generating PWM we use app_pwm library. To decide on the number of cycles of PWM pulses, we use a separate...
Hi,
Is there a way to power only the nrf52832 on the development kit(PCA10040)?
Background: We would like to test a solar power source but we don't want to power the...
Thank you very much in advance for any help.
I am attempting to upload an example firmware on a nRF52832 with the s132 softdevice BLE stack and the example DFU bootloader...
just like
