nRF Cloud — CoAP transport (device shadow) Date of incident: 2026-06-22, ~13:04 UTC — still unresolved at 20:42 UTC (7h38m+) Device: nRF9151, modem firmware mfw_nrf91x1_2...
We are doing a DFU over BLE with the second MCUboot partition on an external flash. Some times Zephyr can't access the flash after booting, resulting in a bricked device,...
Hey, I am trying to implement ecdh key agreement and derivation, but I am getting PSA_ERROR_INVALID_ARGUMENT (-135) from psa_key_derivation_key_agreement: Any idea what is...
Hi,
I have a question regarding the SAADC timing parameters.
I could not find an official specification for the SAADC power-up time (t_PWRUP). While measuring it on my...
I am using nRF54L10 with nRF Connect SDK v3.1. The device connects over BLE, wakes every 30 minutes to read sensor data, and then should enter deep sleep (System OFF). However...
Hi all — I'm developing a custom nRF5340 development board (Raytac MDBT53-1M) and would value the community's honest read on whether it's worth producing.
The goal is...
HI folks,
I have checked the current consumption while connected on an average to be 325uA (with uC taking 4.5uA) so this mean almost 320uA being consumed by the nrf8001...
I have a general question about the RF frequency tolerance of Nordic devices in general. Is the following calculation correct?
Crystal spec = 16MHz, +/-50ppm tolerance...
Are there any plans to add boundary scan functionality to assist ICT testing? If not, are there any other hooks into the part that can be used to test during ICT?
Hello
I'm using a pstorage_register from pstorage.c to register two application storage blocks in flash memory. But I have situation that first module have 6 blocks of...
Hi,
are the GPIO pins broken out on the nRF51 Dongle configurable and can be used for SPI Slave tests? I have a running system powered by a ARM Cortex 4 (Teensy 3.1) and...
We have an early implementation of the v6 SDK DFU ported to support S310 on a handful of devices in the field and need to update them to a new bootloader and we'd like to...
Hi,
With the validation of the BLE V4.2 specification will Nordic be implementing the new features of the spec and if so do you have any idea of availability and dates. ...

Hello Everyone,
I want to start working on nRF51822 development kit for my project. but as mentioned on this site : www.nordicsemi.com/.../nRF51822-Development-Kit
that...
Hello there,
I am using the experimental_ble_app_uart with S110 on nRF51-dk and receiving sensor data via 1MHz SPI every time the timer ticks = 100ms.
Data transfer displayed...
Hey,
I created a custom PCB with the nrf51822 that reads two sensors via TWI and transmits certain data over BLE. I can program the chip, print strings to the terminal...
I am having problems with th Master Control Panel (no response from master emulator). When I search devzone, I see an answer related to this question that says cloed because...
Hi,
I have application where I drive LEDs with shift registers. I need to send 14 bytes via SPI every 200us while I am in BLE connection. Timing should be exact as shift...
Hi,
I have a project where I need to communicate using UART BLE between nRF51822 and a PC (MS Surface Pro 3) with Windows 8.1 and embedded BLE hardware.
I have programmed...
