hi, i am using a cutom board based on nrf5340 mcu , so, while setting it up i am facing the problem in checking logs and led status.
i am uisng the nrf5340dk board to build...
Hi Nordic technical expert,
Can random numbers in broadcast intervals be cancelled or fixed? How to modify the software? Could there be other problems if random number times...
I added ring buffer and UART ASYNCH interface to asset_tracke_v2. I added CONFIG_RING_BUFFER = y, CONFIG_SERIAL = y and CONFIG_UART_ASYC_API = y to prj.conf file. The build...
Hi,
I am looking at setting up some of our team with the ability to flash our custom devices that contain various chips (nrf52, nrf53, nrf91). Assuming the SEGGER software...
Hello,
I have run the GATT throughput example to test the throughput for a long range. My test configuration is as below:
ATT MTU: 247
Data length: 27

Team,
I am using nrf52810, sdk 17, sd112.
I have setup a write characteristics, to receive some long data ( 64 bytes)
// write char memset(&add_char_params, 0, sizeof...
Hello,
I have a BLE peripheral device that becomes the server once a connection is established. The BLE services and characteristics are all custom, I will include the defines...
We experienced an issue in production, in which about 40% of boards had excess current consumption by about 75uA. Root cause was found to be the PIN_CNF of a GPIO pin. During...
Is there any way that a BLE event handler installed with NRF_SDH_BLE_OBSERVER, can stop the execution of other (following) observers?
I have various modules using their...
Hi
I am a student and this is my first project working on BLE. Please keep that in mind.
The end goal is to create a fingerprinting system with a Thingy (nRF6936) as...
I have modified the BLE app Blinky example so that the LED is enabled (state 1) on power up. However, this is not being reflected on the BLE side because when I connect with...
Hi, when debugging, I'm encountering this problem where relevant SPI registers (likely status registers) signaled a successful read before the actual data could be pulled...
We're developing a mobile application which will communicate with a satellite antenna over BLE. We will not have access to the antenna for a few months, and therefore we aquired...
I am using the UART to perform serial DFU on nRF52832. I got it to work fine using nRF Connect SDK 1.8.0.
Now, I need to pass some serial data to the APP when not in DFU...
Hi, I have to develop a new nRF5340/Zephyr/MCUBoot-based device that communicates with a Windows application via USB. The Windows application already manages other legacy...
Hello,
I'm trying to implement a set up of the ble device name from the NVMC UICR register.
But when I try to take it from the register and to set it has a name, it doesn...
Hi,
when using the spi peripheral in slave configuration, what can I expect at power consumption level? does the spi peripheral derive its clock from an internal system...
Hello,
I am using nRF52840 DK's P20 SWD to communicate with an external nRF52840 board . My setup works fine with nrfjprog running from command line. To communicate with...
Is there any example code using a QSPI image as the input for the bootloader instead of e.g. BLE? What format does that have to be in to begin with? Currently doing DFU updates...
Hello friends
I am fresher for Nordic semiconductor . I want to interface triaxial accelerometer of 15MHZ frequency with nrf52840 with inbuilt ADC and transmit the data...
Hello,
I will try to use the macro ZB_ZCL_SET_MODIFY_ATTR_VALUE_CB to define a callback when an attribut is written in my device. But the callback I write is never called...
I had a look on APIs to use UART in Zephyr in the link https://docs.zephyrproject.org/latest/reference/peripherals/uart.html#uart-interrupt-api . There are three types: Poll...
