Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I'm looking for guidance and understanding of how to properly use the KMU and ITS for secure key storage of a key generated on device.
I see that typical ITS use...

Hi,
I have a couple of questions regarding reading the nRF5340 Temperature Sensor. This is a follow-up to the following DevZone ticket: https://devzone.nordicsemi.com/f...
We tested the USB performance on the v3.1.0-preview4 and main it looks like it got even worse.
All tests were done on the attached test project: TestProject

Hi all,
I'm working on a Nordic-based system involving multiple nRF52-series chips exchanging high-rate sensor data over both radio and SPI links. The setup involves two...
I am implementing an SPI master to communicate with an accelerometer using the SPI HAL directly. My chip is marked nrf51822QFACA11609AC. I have implemented blocking functions...
Hi,
When the UART is configured to use FIFO , i use the UNUSED_VARIABLE(app_uart_get(rxdata));
to read a buffer from FIFO.
how can i also receive a number of bytes...
Hi,
I want to do this cycle with GPIO without interrupting it on NRF51 with BLE softdevice:
PIN1 to HIGH level
read value of PIN2
PIN1 to LOW level
Repeat...
Hello, I'd like to do directed avertising to a central which has a random private resolvable address. My idea: both devices share a pre-defined IRK so the peripheral can compute...
I tried, but it does not work.

Hi,
We have a little issue that we at the moment need to cycle power on v3 nRF51822 after DFU.
We have determined the the reason has something to do with the whole complicated...

I'm working on a project based on the ble_app_uart_c central example in SDK 12.1. I'm polling the RSSI of a Nordic beacon using sd_ble_gap_rssi_get(), and the fastest update...
I want to handle 3.3v in nrf52832.
NRF_GPIO_PIN_S0S1 -> NRF_GPIO_PIN_H0S1
Can this be this way?
If not, what should I do?
Also, Can the PWM output to 3.3v?
Hi, I use PCA10040 v1.1 and SDK12.1. My desktop environment is Windows 7 64bit.
As far as I know, the J-Link Edu cannot be used for commercial usage.

Hi there,
We've had our own custom controller made, based on nRF52 (Rigado BMD-300 module).
In the last half of January we'll have a baseline firmware working, but we...
Hi, sending a data packet, then sleeping (memory retention mode), then sending another identical packet causes the receiver to send back an ACK for the first and trigger NRF_ISR...
