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...
We have a custom board with nrf9160, ncs 1.2.0 and modem fw 1.1.1. We experience strange behaviour with the GPS: As an example,on units with 30 min fix intervals, we experience...
I added the commissioning part from the nfc_meshcop example to the mqttsn_sleepy_subscriber example. I tested the nfc_meshcop exaple and worked, so the border router part...
Hi,
I have developed a project of mine based on the nRF52840 DK and now I want to place
the nRF52840 chip on my custom 2 layer PCB board but I think that it might be very...
We still have some Problems to use the Supl client Library, to test it we use the normal GPS example and seems like the connection is available with NB-Iot settings. We are...
I have a product which uses the nRF52840 SoC that will also have NFC functionality. The housing of the PCB is sort of forcing a custom design for the NFC Antenna.
We need...
Hi All,
I am using Segger ISP1430603E board to program my nRF development kit. ( ISP1507AX )
With SES I am able program, debug the application.
I would like to program...
Hi there,
I am wanting to develop a custom PCB for the nRF52833 SoC. I am basing it off the nRF52833 DK! As such, most of the schematic labels are identical.
For our custom...
Hi,
When I do a secure DFU (screen dumps pasted ), it failed with error code 0x8005. It worked on WIndows 7 PC.

Hi,
I am using 2 PCA10040 kits provisioned in the same group. I want to change the payload on button press event from client side which I can receive on server side. How...
I have a nordic kit but the dongle or the kit is not recognized by the computer. Is there a driver that needs to be installed before this will happen? I've already installed...
Hello Guys,,
I am trying to migrate my project form keil to segger embedded studio. My product is based on sdk 12.2.0, using softdevice s130 on nrf51822. I searched for...
Hi,
we have two nrf52840 which shall connect very quickly.
The scan+advertise cycle is very fast (we have no bootloader). After switching on the peripheral it is recognized...
