How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
I want to update 52840DK FW using Matter OTA, but I have not found SOP, could you tell me how to operate?
BTW, I use Raspberry Pi4 connected with RCP as border router. ...
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...
