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.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
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...
I am attempting to update firmware on hardware already in the field. The firmware in the field is based of sdk v11 and has the legacy bootloader for OTA DFU. After some digging...
Hello Nordic,
Due to recent shortages we have switched from a BLE module with external LF oscillator (uBlox Nina-B3) to a module without external LF (Laird BL654). We have...
Hello,
I'm currently starting to develop with the Nordic nRF5340dk and trying to build a mesh network but i'm having some trouble on the examples to understand and buld...
Hello guys,
I have some doubts in the examples you provided for BLE for mesh.
My questions are:
1. - In the examples of light_switch (server or client mode), the nodes...
My goal was to make a bootloader, that, when not requested, still goes do DFU mode for 5 seconds,
so that there is always an option to get to the bootloader after boot,...
I would like to do log timestamping using the UART backend with NRF_LOG.
As described in many devzone posts (e.g. here: https://devzone.nordicsemi.com/f/nordic-q-a/18707...
Hello!
I have a short question, maybe someone can help me.
I set custom advertising data in the following field on the advertising side:
Now I want to read this data...
Hi all,
I am developing a BLE device prototype. There will be multiple such devices. How can I write the UUIDs to flash while flashing the hex file. Or how can I get the...
When I call this function on any of the Development Kits, my application restarts just like when I power up the DK for the first time (after being programmed of course) or...
Hi!
I'm trying to make the NFC feature on a custom board while having BLE (soft device). When I run the nfc record_text exemple project on my custom board, everything works...
We plan to design a module that wirelessly connects via the nRF52833 chip with RF amplification, 2 PWM outputs and multiple
Digital I/O interfaces,One ADC interface and...
I have developed the application code for light node in ble mesh network.
I was able to see this error quite often:
