We need to set a GPIO pin in MCUBoot to activate an external USB hub chip so the USB DFU will work. I would like to do this with code in our project rather than directly modifying...
Hello,
I’m working on a Zephyr-based application using the nRF5340 where I need to optimize power consumption. The intended behavior is:
The device should stay in...
According to the nRF52832 Product Specification, “A step increase in supply voltage of 300 mV or more, with rise time of 300 ms or less, within the valid supply range, may...

Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hi Sir,
We would like to use the Radio test to do the basick TX/RX test in SDK 15.2
We use the nRF52840-DK for test and follow the CLI document .

Baud rate 460800, error code NRFX_ERROR_INTERNAL(1) occurred when the serial port received data。
I want to know how to avoid this problem, the current transfer rate is less...
Hi
We need the recv() be blocking until the full amount of requested data can be returned or the operation was timeout, how to achieve this?
I tried flag MSG_WAITALL but...
Hi. Can anyone think of a way to use the nRF52832 (probably Timer) to detect approximately 125KHz-150KHz variable square wave down to about a 1Hz resolution? I'd like to detect...
Is there any example for Directed Advertising? I'll design my NUS central and peripheral use Directed Advertising, because I would like to have other bluetooth devices connected...

Do you have any recommendations, tutorial, blog, or getting starting guide for a developer wanting to use Mesh and BLE on the same node? Any information would help. Does one...
Hi,
After long use of BLE communication I sometimes get return code 8 from sd_ble_gatts_hvx.
My questions:
1. This return code is cryptic. Is it associated with defined...
I am trying to configure the CryptoCell on an NRF52840 to use AES-CBC encryption with PKCS7 padding. When I call the following function, it returns SASI_AES_ILLEGAL_PADDING_TYPE_ERROR...
