Hi,
I am working on a project which has external flash (FM25V01A ) connected to nrf52832 board over SPI. And when building the project, I am getting the following error...
Hello,
we run an application on a custom board with nRF52840 powered by an external power supply and buffered by a supercap. The supercap then provides the energy for the...
Hi,
I have 2 nrf52840-preview dk board. All of a sudden both the devices are not working any more.
I have referred to some suggestions and tried all the below cases and...
Hi!
Absolute beginner here. I'm trying to use npm1300 (using the evaluation kit for now) with an RP2040 microcontroller (also using RPi Pico dev board). I am powering RP2040...
Currently, I'm using nRF5340 Audio on a homemade board, and I've managed to get the sound input from the gateway as a LINE input and the sound coming out of the headset, but...
Hello ,
I am trying to program external custom board through another nrf52dk via SWD interface to check if external programming method works. The connections between two...
We are using BLE and QSPI at the same time and want to have maximum RF range. Sensor data is collected, encoded, and written into flash via QSPI. This goes on for a few minutes...
I have a question: Is it possible to use BLE Long Range mode (Coded PHY) in the NRF52840 with mobile phones? If not, is there a solution to use it in parallel with normal...
I am using NRF52840's NFC with apple wallet but it requires certification from Apple to be used as tag reader. How can I get it certified so that I can read data from apple...
Hello,
