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...
When using the USB for logging date, I am able to see my file by simply plugging a USB connector; I can also view the contents of the file by double clicking on it. In such...
Hello,
I'm integrating mesh and freeRTOS and having problems with interrupts priorities on both sides. It's a little bit confusing to set the interrupt priority on each...

Hi all,
I am working on an application where I have an application MCU and my idea was to use nRF52 as a 'modem' over serial API. The device I am making is supposed to be...
When nrf52 board and tablet PC connect, I set the tablet PC in sleep mode. Then how can I wake up tablet PC via pushing a button on nrf52 board. Maybe one event can realize...
