I am working on an nRF54L15 project and started from: C:\ncs\v3.0.2\nrf\samples\bluetooth\peripheral_uart as the base. I would like to trigger an interrupt once every second...
In the reference schematic design of the 54L, why does the RF circuit use three LC circuits? What is the purpose? This approach would likely result in higher insertion loss...
I have made a PCB using a BL5340PA module, to start i have tried a simple code to see log from RTT using the SWD SWCLK pin, i am using an NRF5340 DK as debugger/programmer...
Hi apparently the examples are not working out of the box. I do not see any documentaiton on what has to be done for them to work. Can you advise me on what i shoud do to...
This table for the absolute maximum ratings isn't clear.
Can you help confirm the unit "y" here for RRAM retention? Is this years? Is it cumulatively years or consecutive...

Hi,
I'm looking for some guidance.
I'm using a HolyIoT nRF54L15 dev kit to evaluate their nRF54L15 module.
I am currently looking power consumption.
I have tried the...
I'm wanting to repetitively read the SPI buffer as a master to check a status bit. I figure there's no sense in using the DMA when I can read the SPI RXD buffer directly....
Hi
I am trying to use the two GPIO pins. One GPIO pin is configured as a input and connected externally to a button.
The second is configured as an output pin. I want...
