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...
hello, I have developed nrf52840 for multiprotocol ble/zigbee.
I want to simply send & receive zigbee packet not using zboss network.
I already tested example "wireless_uart...
I have two nrf52832 boards, both being developed with SDK v11 and the s132 soft device.
Board one is given commands over UART to communicate over ESB with board two. Board...
Summary of Issue: 8 dongles are used in a test system that each dongle will communicate with 1 device. Testing can start ok but after some runs, one of the dongles can not...
According to nRF52840 Product Specification v1.0, a ll the reference circuits are designed for use with a 50 Ω single-ended antenna. Why is the calculated result by AppCAD...
What would be the best example to start with my project which involves sending sensor data to mobile phone applications using ble? i have nrf52 DK and SDK 15.0
Thanks,
We're using RTT with an 52832 and it works fairly well, really can't complain much except...
On my PC everytime I launch a debug session I need to launch RTT viewer exe...
I'm using Rigado BMD350 evaluation board. I'm printing to serial port (COM3, speed 112500) using NRF_LOG_INFO.
However, the logging does not appear until debugging is...
In a recent project, me and my team have been trying to send data from 3 PTX devices to a single PRX device (the devices are all nRF24L01+) at a constant rate of 1600Hz from...
hi all!
Like two of my predecessors, I am trying to put a CR95HF into operation. I chose the nRF52832 DK as MCU (SDK 15).

I changed only source clock part to internal clock and it doesn't do advertising. When I debug it, it starts to run. When I finish the debug session advertising stops again...
Hi,
I've built a custom board with nRF52832, without other MCU like PCA10040. I use a FT232RL to bridge the USB to nrf UART, flashed nrf5 uart connection firmware ble_connectivity_s132_uart_pca10040...
Hi, I using nrf52810 with custom BLE profile and 4 sec advertising + continuous RTC. Device is battery powered (750 mAh) and PMDC motor equipped. Most of time (90% of day...
Hi,
I am designing my custom board with the nrf52832, which would perform the BLE and I2C functions. I wonder what necessary and basic peripherals it needs, like crystal...
Hi,
I would like to synchronize 2 Sensors with one dongle. So the problem is that we have two sensors and we want to start the measurement at the more or less (1 ms) exact...
Hello,
I am new to BLE as a technology and have a question regarding how Peer Manager handles bonding.
As I currently understand, the function of bonding is to enable...
