Before buying two nRF54LM20-DKs, I need to know which way is supported. Our own protocol uses RADIO directly: in each 20 ms period a SYNC goes out at 30 µs, started by a TIMER...
The Thingy:91 X board files allocate only 32 kB to the TF-M secure partition (slot0_s_partition). This is too small to support CONFIG_TFM_PROFILE_TYPE_MEDIUM, which is required...
Hi,
I am designing a PCB using the nRF54L15 (QFN, 3.3 V system) that must meet IEC 61000-4-2 Level 3 (±4 kV contact / ±8 kV air discharge). The on-chip ESD rating is only...
I am developing a proprietary 2.4 GHz distance measurement with two-way phase-based ranging and RTT on the nRF54L15.
I intend to control the RADIO peripheral directly, without...
I am seeing a reproducible interaction between asynchronous UART support and the TWIS peripheral on an nRF52840 running NCS v3.4.0.
The application uses nrfx TWIS to implement...

I am attempting to send 13 bytes over UARTE1 on the nRF52840. I'm using the ASYNC API in Zephyr. When I look at the output on an oscilloscope, some of the bytes show up in...
Hello, developers! I am wondering if the Light switch demo and the thingy52-mesh-provisioning-demo serve the same purpose. I tried to run them combined: the first one on an...
Hi,
I'm completely new in the nordic development area and I'm trying to read sensor data from a DHT22 Temperature and Humidity sensor.
I'm used to directly include libraries...
Hello:
I am working on a USB bootloader project. I am running into the issue where the USB will not boot on first start up but boots following this. I read some of the previous...
It appears that there is a bug in the antfs.c sample code in version 15.3.0

I have a custom board using nrf 52382 with NFC. While Developing application I have checked nRF52832 Revision 2 Errata .
I have a question related [218] NFCT: Frame Delay...
Hello,
Our application runs over nRF52840 + SDK16 + FreeRTOS and we are using libuarte application to drive the UART. We found that the app_timer_freertos.c doesn't provide...
Hello ,
When i am using sdk functions with freertos some of the callbacks/functions requires (for example) xTaskNotifyFromISR() instead of xTaskNotify .
So how can i decide...
I am going to mass-produce beacons with built-in ble uart app sample.
However, I am not sure those produced beacons will have unique mac-address.
In my view, those are...
Hi all i am trying make a communication between esp32 and nrf52840 using UART. Initializing the uart driver was proper and pins also correct. when nrf start transmits then...
Using nrf52810 SDK 17 ble_app_hrs for my example, and i add some code about the passkey
Now the situation is after I enter the passkey on my Iphone nRFconnect app, and if...
As with my recent inquiry about a softdevice assert at PC=0x24e70 , I'd like to know which assertion fails in softdevice S132 version 7.0.1 at PC=0x157ec.
Is there a table...
Hello,
I observed a weird behavior when I changed to nRF52840-DK from nRF52840 Dongle. I am using the device as an SPI slave connected to a Raspberry PI as SPI master. ...
While trying to execute the light switch example, i was able to set the nrf52840 as evaluation board as proxy server but failed to do the same with the dongle.
2)When...
Hi,
When running the at_client example, I send the AT+CFUN=1 command via the LTE link monitor. After a few seconds, the nrf9160 reboots.
I want to say that before my program...
