Hi, Background: We're developing wireless application with the NRF5340-NRF7002 chipset, similar to what's on the 7002DK board. We'd like to put the system to lowest power mode when it's not being used. I found two samples related to this: nrf/samples/wifi/shutdown and zephyr/samples/boards/nrf/system_off My questions are: Which sample shall I base my project on? The wifi/shutdown sample page states that " This also demonstrates how to achieve the lowest possible power consumption in the Host SoC (nRF53 , nRF52 or nRF91 Series) when Wi-Fi is enabled but not being used." - How is this achieved? I can only see function net_if_down() is used. I assume this will only turn off the nRF7002 wifi chip, but not the host? The system_off sample uses sys_poweroff () function, will this shut down both nRF5340 and nRF7002 chips? What happens when BT and/or Wifi are being used? Many thanks in advance!

Dear Nordic, We made an attempt to use the external flash in the LwM2M sample. We tried to follow this: docs.nordicsemi.com/.../nrf9160_external_flash.html As soon as we add: ' / { chosen { nordic,pm-ext-flash = &mx25r64; }; }; The sample stops working, it does not even start. We guess, it is related with MCUBoot issue or not having pm_static.yml file. Could you please tell us how the proper configuration shall look in this case? Regards, Marcin

I need to detect the VCC voltage on the nrf52833 on power-up and wait till it slowly ramps up to 3V. Is there a way to do this using the Power-Fail Comparator. I found another example how to enable the POF, but this will give me an event when the VCC goes below my 3V threshold, which is the opposite of what I'm trying to detect.

Hi everyone, We have devices using the BLE module (nRF52) deployed in clinics for testing. They have been functioning without issues until recently when we noticed occasional BLE disconnections. The following image shows data from one of the affected devices. Its RSSI value dropped significantly to -90 dBm, indicating weak BLE signal strength that could explain the disconnect. However, the device was positioned close to a tablet running the application connected to it, where the BLE signal strength should have remained strong. This inconsistency is what we find puzzling. In another case, the RSSI value was within acceptable range (-68dBm), which couldn't lead to the BLE disconnection. We're thinking of if any issue with code optimization. Any suggestions to further investigate this issue would be greatly appreciated. Thanks!

Does the NRF8240 using the HCI UART sample support setting a public address? https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/samples/bluetooth/hci_uart/README.html I get this error when trying to set the address via the btmgmt tool via: `btmgmt public-addr ` Set Public Address for hci0 failed with status 0x0c (Not Supported) Bluez5 version is 5.54

Hi I have set up VS Code (1.93.1) on my Mac (mac OS 14.6.1) with nRF packages and zephyr installed. My nRF5340 DK is also found (however, instead of a nice identificaiton name, it shows a strange number!?). Now, the project did build but now I am unable to download it, because it doesn't show any actions. Issue: There are no "ACTIONS" shown. Why is that? So far I have installed - nRF Connect for VS Code - nRF Connect for VS Code Extension Pack - nRF Kconfig - nRF Terminal - nRF DeviceTree - ... - anything missing? Does anyone have a hint? Thanks in advance!!

Hello, We are in the feasibility phase of updating a product to include a nRF9151 modem connected to a nRF52840 via a single UART. The modem will operate in SLM (Serial LTE Modem) mode. This must fit on our existing PCB board size which is already quite small, so board space is limited. In regard to nRF91 modem FOTA, my understanding is that in order to perform a "full modem" FOTA update (as opposed to delta FOTA update), an external flash of 4 MB or larger is required to be connected directly to the nRF91 modem to store the downloaded firmware image. It is also my understanding that delta FOTA updates support updating only from one minor version to another (For example, 1.1. 1 to 1.1. 2 ), and full modem updates are required to update from one major version to another (For example, 1. 1 .x to 1. 2

Previously, nRF Connect SDK was working without issue. However, now when I try to create a new build configuration, it hangs at the following step: It's unclear why this began happening, it was working fine before and occurred in the middle of a session where build configurations had been created successfully several times. Although I can't create new build configurations, I can still build and flash existing configurations as normal. This error has happened many times before, but usually is fixed by restarting VS Code. However, this solution is no longer working. I also tried restarting my computer but it didn't help. I'm aware a similar ticket was raised here but this thread doesn't provide a fix. When using the command line solution provided in the original post, it still hangs at the Gnuld step. nRF Connect SDK 2.8.0 VS Code 1.95.3 macOS Ventura 13.0 Apple M2 nrfjprog version: 10.24.2

I programmed a nrf52840dk board (PCA10056 3.0.0 2022.7 1050288497) as a sniffer. It works well. Now I want to flash it to zephyr samples/basic/blinky by "west flash". west flash -- west flash: rebuilding ninja: no work to do. -- west flash: using runner nrfjprog -- runners.nrfjprog: reset after flashing requested FATAL ERROR: Unable to find a board; is the board connected? ls -hal /dev/serial/by-id usb-ZEPHYR_nRF_Sniffer_for_Bluetooth_LE_49F8F9D7E8AE3B9E-if00 -> ../../ttyACM0 I tried to hold RESET button and cycled the power but it still ran into sniffer. Thanks!

Hi Devzone. I have a PCA10056 that I'm using to set up for CI / HIL testing, using an external nRF52840 on another PCB. The external SWD on P19 is working perfectly. I am able to flash and debug the external nRF52. I'm trying to connect the external nRF52 UART to RXD/P0.08 and TXD/P0.06 for scripting, without HW flow control. The interface MCU does not seem to be routing the UART traffic to USB CDC I can verify my UART signal on TP2 / IMCU_RxD, so IF_OFF seems to be set correctly. I tried a few things, such as flipping SW6, but that causes my USB CDC to drop out. SW7 does not seem to affect anything either. When I use the on board nRF52840, the virtual COM port does function. So this is strictly a problem when trying to inject the external UART to the virtual COM port.
