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...
Hello,
We have a Nor flash connected to the QSPI and another peripheral connected to the classic SPI.
Due to the errata [159] , the HFCLK128M is running at 64MHz and...
In the nRF9151 Product Specification, there are maximum gain requirements for the LTE antenna implementation, specific to supported bands. It is my understanding that any...
Hi,I have been using NRF5340 Audio DK and I able to get data using SPH0645 using i2s_read function and able to transmit data to amplifier TAS2562 using i2s_write function...
How does the Online Power Profiler for Wi-Fi tool calculate energy consumption, and is there a formula or document explaining its energy consumption calculation principle...
We are using a Nordic 52840 along with an NPM1300 power manager and rely on Nordic's algorithm (via nrf_fuel_gauge_init and nrf_fuel_gauge_process ) to calculate the battery...
Good evening,
I noticed that the IMEI for the nRF9161 is not embedded like it is for the nRF9160, and it requires retrieval either through nRF Cloud or via the API. However...
Hi all,
I've been playing around with the Nordic cellular boards (nRF9151, nRF9161, Thingy 91) and keep running into the same issue.
I'm using the Serial LTE Modem application...
Hi,
I am unable to use the new nrfutil to do even a device reset of my devkit. I have installed the recommended segger version and the apple-silicon version of nrfutil...
Hello,
I'm using nRF SDK 2.7.0 and trying to implement PSK type bonding.
From quick ChatGPT search it looks like in past SDK versions there was a way to inject pre shared...
Issue: I am trying to flash the zephyr sample code into custom board with nrf52840 chip. I am frequently getting the recovery failed error or the JLinkARM DLL error. I have...
Hello, I am currently working on a project where i need to read the consumption with a PPK2 through an ESP32(use it in place of a computer). Is there by chance a pin on the...
Hello everyone,
