We have previously used nRF52840 and for the latest iteration of our board design we are updating to use nRF54L15.
We are aware that for nRF52840 we could map any pin to...
Hi,
I faced with an initialization issue of combination two features: MCUMGR and UART_ASYNC_API. I get a crash right after the FW starts. It looks like the SW configuration...
Can anyone clarify what information is stored in the nrf9160 chip barcode? For our manufacturing tests, we'd like to use a barcode-readable identifier on each board, and the...
I am adding Softdevice BLE to an existing firmware build(without softdevice, only USB) using Visual Studio and SDK 17.1.0 (Qorvo), on a Murata 2AB,
the firmware boots softdevice...
Hello,
I've inherited a project to create an iOS app that can communicate via BLE to UART RS232 to devices in the field using a proprietary protocol and at 115200 baud and...
We are using an nrf51822 processor, running off of 2.7 volts from a switching power supply, powered with 12.4volts. The processor has simple gpio connections, and a battery...
Hi,
The structure nrfx_spim_xfer_desc_t contains both tx_length and rx_length fields.
Is there a situation where tx_length != rx_length ?
Thanks,

I have a nicely working application that occasionally hangs. I have managed to trap a "hard fault" under the debugger (using VS with GCC). I have the system halted with the...
hello, Nordic developers!
I needs help develop rnf52840.
Goal
My goal is ble & 802.15.4 mutiprotocol, not using zboss network.
Actually, It is the same situation as...
Hello,
I am in the process trying to send multiple packets over ble but cannot seems to figure out this UART example.
I have read many posts that use ` ble_nus_string_send...
My understanding is that the nRF52840, which is the only nordic device to support the long range bluetooth physical layer. Additionally this chip requires SoftDevices 140...
Good day,
We are planning in developing our own custom-made nRF52840 PCB using the reference schematics provided by Nordic Semiconductor.
In the initial phase of our...
Hi,
This is more of a bug report than a question, but not sure how to get in touch with engineers outside the forum.
In app_util.h (Using SDK 12.3.0) there are two...

Dear Nordic,
I bought three nrf52840 dongle.
How i test the mesh i am totally confused how its programmed and how mesh tested with this nrf52840 dongle can you help me...
We are trying to do final optimization of the load capacitors connected to the 32MHz crystal on the nRF52840. A value of 13pF for both capacitors results in a frequency that...
Hi,
Using SDK 15.0 via legacy nrf_drv_power, the nrf_drv_power_sleepevt_init causes fault:
It calls nrfx_power_sleepevt_enable but never calls nrfx_power_sleepevt_init...
