Hello,
I have a legacy project that is using nrf5 sdk v17.0.2. I need to add the BLE DFU functionality to this project based on the nRF52840. Are there any examples on...
I was doing some developement for a custom board on NCS v2.9.1 when i noticed some of the changes i was making in my prj.conf weren't being set in the application. My impression...
In my circuit I have a MOSFET which disconnects the battery. There is a GPIO pin which turns this device on and I'm using regulator-fixed to drive it during start-up. A short...
We are currently using ncs 2.9.0 on an nRF5340. We use the BT_HCI_OP_VS_READ_VERSION_INFO to determine at runtime what version of the BLE stack is present. This information...
Hi I'm trying to load a custom board with nrf9160 with the Serial LTE Modem, and route the AT commands to the UART from a coprocessor (ESP32C3) I have followed the guide on...
Hello,
we have a working system on the nrf9161 that works without zephyr. We have our own secure firmware that successfully uses the cc310 after we start the actual application...

Hello,
I've checked the timing diagrams for the CE and IRQ on the datasheet but I would like to know if anyone has actually tested them with an oscilloscope? If yes could...
I am using SDK 11.0.0 on a nrf52832, with FreeRTOS and SD132 2.0.0. I configure the FreeRTOS port so that it uses RTC1 as SysTick. Depending on some compilation macros, my...
Assuming that all peripherals that require the high frequency clock are disabled / turned off / stopped, how long does the HFINT oscillator run after calling __WFI()?
And...
What's the delay from setting the Start / Stop task in an RTC module to when the RTC actually starts or stops? Is it less than 1 clock cycle on the CPU (15ns)? More than one...
Hi, I am using the nrf52 dk to sample two analog inputs through PPI.
My question is if I can use different bit resolutions for each analog input?

Hello !
I have a problem with my program (on a nRF52 board) : when I send a value to the board via BLE, it seems that my static variables are reset.
I noticed that, because...

Hi,
I'm new and I'm a student.
I have to connect the adxl345z to my board mb39c811-evbsk-02.
It has an nrf51822 integrated.
Someone can explain which pin of i2c/Gpio i...
We wanted to update the firmware over the air, We needed help for zip file creation(.dat file, .bin file and .json file). There are many links online, We needed an link which...
Hi,
I'm developing to NRF81522 mcu, using a softdevice S130.
The MCU is connected to another device through the UART peripheral.
