Hi Sirs
We are planning to use the nRF54LM20A/B together with the nRF21540 FEM in our design, and we have a few technical questions regarding TX power control and FEM...
Hi Nordic Support Team,
We are currently evaluating the nRF54L05 DFU single-slot sample in NCS v3.3.0.
Our question is: Is it technically possible to configure the single...
Hi,
I'm using the published nRF54L15 DK hardware files and noticed something that I don't understand.
On the nPM1300 section of the schematic and PCB:
Pin 20 ( VSYS...
we are developing solutions with PMIC type=PM1300, we eager to know the internal LDOs PSRR.
i have read 171 page of PM1300 datasheet, but cannot find PSRR data or the PSRR...
nRF54L15 PDM clock runs at ~1/32 of expected (PCLK1M instead of PCLK32M) on a custom board - works on DK
Summary
On a custom nRF54L15 board, the PDM peripheral clock ...
HI
I am currently using the nRF54L15 chip with NCS 3.2.1, carrying out secondary development based on the periodic_sync_conn sample project. I intend to adjust the transmit...
While configuring a scene, the blind device is not visible in the scene settings screen, so it is not possible to set or save the blind position as part of the scene.
Steps...
I'm trying to use BLE library for python to communicate with one Nordic nrf51844 chipset. Because one characteristic is notification enabled, I need to enable notification...
Does there exist a white paper describing some typical PPI use cases with coding examples? The only one I've found is the peripheral/gpiote example and it is severely lacking...
Updates are moved to the end of the question
I created a modified version of pca10028.h and boards.h and have preprocessors changed so that the following new config is...
I example test ble_central and ble_peripheral of ble_app_uart.
Radio TX and RX test is OK.
It confirmed the data communications relating to uart_event_handler function....
I'm trying to get a time stamp using app_timer_cnt_get(&ticks), but the ticks always equals 0. And I have called APP_TIMER_INIT() to init the app timer. I have no idea why...
Hi everyone, I have been given a nRF51-DK board and I should use it to send data retreived from a sensor to it through Arduino, to finally receive it in my cell phone. I am...
Hello everyone,
I'm brand-new here. I have developed quite a bit of software on desktop PC's, but this is my first experience with embedded programming. A few weeks ago...
Hi Team,
So I downloaded the new nRF Connect for OSX. I inserted my PCA10031 nRF51 dongle into my USB port and the relevant lights lit up. However nRF Connect does not...
I am quite new to embedded firmware development and definitely just two days old into Nordic nRF52 development.
I want to just setup a 25% duty cycle clock output on GPIO...
Hi,
I have a very sophisticated program on nRF51822 with SD120 which uses SPIS (as an RX for another board) and UART. I used "spi_slave_example" as a base program.
I am...
Hi, in the (not great) mBed PWM driver, when setting up GPIOTE to toggle the output pin they do this:

Hi,
I have a application that needs to advertise only for 120 seconds and on change in values of accelerometer , it needs to start advertise again.
presently i have a...
Hi,
I've been using these parts for a few years (the 51) and recently did some work getting the boot loader to be joined together with the application into a single burnable...
Hi,
I wish to exchange the sensor form mma7660 to hmc5883l, so I simply replace it with my own function just like mma7660 did.
Those function are

Dear All.
As I know, nRF52 support PDM mic. So, I'll make recording sound with nRF52.
But, I do not find PDM example on SDK 11.
Please notice me, where is the PDM mic...
