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...
Hi,
We are developing an application that requires synchronization between two or more nRF9160-based devices. We have the following requirements and constraints:
Required...
I'm using the prebuilt Aliro stack (libaliro.a, nRF52840), when a session fails inside the library we have no way to get the resulting AliroErrorCode. The stack entry points...
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.

Hi,
I bought nRF51822 Evaluation Kit and would like to blue wire an external MCU( Kinetis Cortex-M) to talk to the SoC. It looks like the SoC on this board has many GPIOs...
Hi,
Could someone can explain, how to handle Static Passkey in iOS Central application?
I would like to know whether iOS application allows static key based pairing or not...
Hello,
i'm programming an iOS app to connect to the nRF51822 (peripheral). The Problem: Any kind of authentication and encryption is needed, but in the final Product the...
I've seeing random crashes at that originate from ll_lm.s0.c:404. It seems to be happening when I have uart logging turned off. I don't think i've seen assert callback called...
Says it all in the title. I'm making a sensor which puts its data in a non-directed non-connectable advertisment packet. I want to read the sensor just before it is sent....
Hi,
We are designing our 2nd pass design based on nRF51822 this would be our production version PCB.
We would like to have our Schematics,Layout and BoM reviewed from your...
Hi,
I am using softdevice-7 and SDK 6.1 for our application. I want to implement static key pairing for serial port over ble application "ble_app_uart".
I have implemented...
I have a 384 byte, writable, variable length, vloc user characteristic and I want to trigger an event when the write completes so my application can operate on the data. ...
Hello-
I am trying to program a custom nRF51822 board with a J-Link-lite.
From the J-Link-lite, I am using the 10-pin header and have it wired like this:
I'm using pins...
I have a situation where I need a software PWM for several channels, which are multiplexed via a shift register.
The output loop needs to run at several kHz for this to...
Because of the limitation in the GPIOTE hardware that only one channel can be connected per GPIO , care must be taken when changing a PWM duty cycle. If for instance the compare...

Hi Nordic
I do not know why sometimes program can build pass in keil ,but can make nrf51822 do not work and unable download program . For this , I have damaged a lot of...
Does the nrf51822 support 2 spi masters (on different pins)? I want 1 spi channel to talk to one set of peripherals, and the other to talk to another set. I see SPI_MASTER1_ENABLE...
