To be able to upgrade FW through UART, a bootloader for nrf51822 is required in my project. I have tried out the example bootloader in SDK. But this example is using softdevice...
I followed the forum posts and nan-29 to get eclipse 4.3.2 to successfully connect to JLinkGDBServer via a Segger J-Link EDU on Ubuntu Linux.
I can start the GDB server...
I'm using Softedevice 6.0.0 and SDK 5.2. and Keil 4.7.
I Modified bootloader project so it compiles with both ble and hci transports. Currently I use button_0 and button_1...
I am working on the proj that needed 2 MCU and nrf51822 work as slave.
I would like to know any ref on how to firmware upgrade on board without external tool?
We're looking for a Nordic nRF51822 based low profile/small USB dongle that we can use for our iBeacon software.
It would need to come complete with casing and the ability...
Hi all,
i want to establish connection between two threads in cmsis-rtos, can i use
1) semaphore to do this?
2)message queue should be used or any other ipcs can be...
Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
After flashing the official example hci_uar onto the nRF5415-DK, I proceeded to use "udo strace -o btattach.log btattach -B /dev/ttyACM1 -S 1000000 -R“ to bind it as an HCI...
Hello, I’m working with the nRF9151 and testing DECT NR+ functionality. I already have the binary image of the DECT NR+ PHY firmware and it works fine. I’m just curious—is...
Hi,
I've successfully incorporated MCUBOOT into software we developed for the nRF5340. I'm also able to start serial-recovery by activating a GPIO, reserved for this purpose...
Hi, I’m trying to build the github.com/.../neuton-nordic-thingy53-ble-remotecontrol project using nRF Connect SDK v2.6.2 . I added the BMI270 sensor on SPI3 in my DeviceTree...
Hello,
I am at the very, very early stages of my project, doesn't it even a name yet. Right now I am thinking of using nrf52840 for a Bluetooth operation while being supplied...
Hi,
I am working on a PCB with the nrf5340 and I have been following the reference schematics and the hardware files from the audio DK. I want to have the bare minimum...
Currently, I have configured cs-gpios in the device tree and loaded the SPI in the main function. Why is D0 (representing CS) kept high in my experimental waveform, and SCLK...
Hello! Some time ago we bought your NRF54L15 dev kit 0.9.1. ( for channel sounding BLE6) with an aim to make a product for staff positioning at underground mines. For this...
I used the application_update example, added external FLASH support code, and incorporated the nrf\samples\wifi\scan code. Initially, the NRF9151 and NRF7002 communicate normally...
Dear All.
I tried to test and evaluate LoRaWAN stack on Zephyr, without success. I will need more time to debug what is happening by the logic analyzer. Meantime I attached...
Hello everyone,
We’re developing a prototype using the nRF52840 MCU, and we need to flash a bootloader over SWD using a 1.8 V system powered by a PMIC. I’m exploring whether...
Hi,
I have a question on the correct usage of queues in Zephyr.
I have a firmware program that uses multiple threads, and as it has developed over the years multiple threads...
Hello,
We are investigating a sudden battery drain issue in our nRF52832-based wireless product. During power profiling, we noticed unexpected current glitches (please see...
