I am using nRF54L10 with nRF Connect SDK v3.1. The device connects over BLE, wakes every 30 minutes to read sensor data, and then should enter deep sleep (System OFF). However...
Hi all — I'm developing a custom nRF5340 development board (Raytac MDBT53-1M) and would value the community's honest read on whether it's worth producing.
The goal is...
I don't know why I didn't notice this blurb in the reference manual sooner. In pretty much all peripheral sections (such as SPI), you have this warning:
Therefore, the...

Hi,
I programmed the NRF51-dk to take ADC samples and transmit those values at 8 bit resolution. Now I want to send a 10 bit resolution value over BLE UART, but I believe...
Hi everyone,
In my low power application , I use PORT EVENT to detect the interrupts of my two pins.
when I use only one pin interrupt, it's working well .
But with two...
Dear All,
We are implementing 8 Pheripheral Nodes and one central node with S110 and S120 respectively.
We have our custom board with us we are able to connect the pheripheral...

Hi.
I have interesting UART problem in Ubuntu. The multilink example only outputs one character at time, and line change doesn't change line. However if I flash another...
Hi,
We are using 52832 to developing.We need DSP to finish the arithmetic.
Can you tell me how to use the DSP on 52832 ? Do you have same examples?
These algorithms...
I have an nRF52 dev board and I'm trying to build and download some of the example programs.
The example files were downloaded using the Pack Installer in Keil MDK-Lite....
