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...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.

Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
hi support team,
may i ask how to test 54l15+21540 dtm? i have send code to customer, but they feedback to me that the output power is 15db, not 20db(using serial send command...
Hello,
The customer, T&D would like to registrate their product to Bluetooth SIG.
Then, design number shoule be required, however, regarding SDK3.0.2, there isn't any...
I am working on an nRF54L15 project and started from: C:\ncs\v3.0.2\nrf\samples\bluetooth\peripheral_uart as the base. I would like to trigger an interrupt once every second...
In the reference schematic design of the 54L, why does the RF circuit use three LC circuits? What is the purpose? This approach would likely result in higher insertion loss...
I have made a PCB using a BL5340PA module, to start i have tried a simple code to see log from RTT using the SWD SWCLK pin, i am using an NRF5340 DK as debugger/programmer...
Hi apparently the examples are not working out of the box. I do not see any documentaiton on what has to be done for them to work. Can you advise me on what i shoud do to...
This table for the absolute maximum ratings isn't clear.
Can you help confirm the unit "y" here for RRAM retention? Is this years? Is it cumulatively years or consecutive...
I am experiencing an issue with my nRF52840 DK board. When I initially connect the board to my PC via USB, the debugger LED (LED5) blinks briefly but then turns off. Additionally...
Hi,
I'm looking for some guidance.
I'm using a HolyIoT nRF54L15 dev kit to evaluate their nRF54L15 module.
I am currently looking power consumption.
I have tried the...
I'm wanting to repetitively read the SPI buffer as a master to check a status bit. I figure there's no sense in using the DMA when I can read the SPI RXD buffer directly....
Hi
I am trying to use the two GPIO pins. One GPIO pin is configured as a input and connected externally to a button.
The second is configured as an output pin. I want...
I am trying to complete the course "nRF Connect SDK Fundamentals" using a nRF52840 DK board (version 3.0.0) connected to a Mac Mini (Intel processor) running macOS version...
Hello,
I'm experiencing high current consumption with Zephyr OS. I'm using SDK 3.1.0 and the device still draws about 900 µA, and I don't know why. Although I have a custom...
