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...
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,
currently I'm testing several options to transfer data in broadcast manner, i.e. in fact extended advertising due to the amount of data to transmit. A few days ago,...
I want to do firmware updates over BLE. To do that I added these settings to my prj.conf which I mostly got from the smp_svr example:
This "works" but it uses the default...
Dear DevZone,
I would like to add a nrf21540 range extender to my board based on nrf52840 MCU. Our lab is based in Italy and we would need to respect the regulamentation...
Currently, I am following guide of zephyr sample: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html But when...
Hi
we are developing a successor for one of our products based on the nRF9160. One important feature is the debug UART. There are 2 ways to connect to this UART. Either...
Hello,
We have a software running on the nRF52832 which was developed with the nRF5 SDK. It contains a bootloader, S132 softdevice and our custom application.
The bootloader...
Hello,
When looking at the datasheet, we see that the modem power consumption can be really high in high power tx scenarios, 23dBm for example the modem consumes almost...
Hi,
I am looking to perform programming on a nRF52832 on a custom PCB. So far I am planning to use an SWD connection with my nRF52DK to upload my application.
1. I was...
Hi,
I'm looking for some documentation for both projects. While there inline documentation and example projects are existing, I couldn't find any javadoc (or similar,...
Hi,
I want to use two SPI instances (0 and 1) in my project. I am able to modify the example SPI project to use 2 SPI instances as in the code below and setting #define...
I'm trying to get the ADC running on an nrf51DK, however whatever configuration I use it always outputs a value equivalent to ~0.6v input. I've tried with the basic ADC example...
I bought a product with NRF52840 as MCU. Now I want to communicate with other devices over RS485. So I had to make some changes. I have the following questions and hope to...
i try to build simple hello world program in c++. it successfully compile just yesterday, but somehow it fail to compile now. on the log it seem to use /usr/bin/c++ to compile...
The following code snippets produces Error code 0x0005 when trying to update a characteristic value via custom characteristic programming nd connected to nRFConnect app: ...
The nRF52833 datasheet lists a number of pads as "N.C." however I could not find anything in the datasheet about what to do with these pads. Is it safe to route traces over...
