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...

I'm trying to build a quick application to scan for all devices in the vicinity and print out their details (device name, manf data, RSSI, and BLE address). I am parsing the...
According to BLE 5.1 Core Specification Coded PHY and CTE are mutually exclusive. But losing 4xRange to implement Direction Finding is a big loss if, for instance, you need...
Hello,
I used the examples\peripheral\libuarte example to implement a driver for NBIoT DCE. I embedded the sample in my project and started debugging. Although the transmitter...
I got an error at pc = 0x104F0 (id = 1, pc = 66800, info = 0). My code is advertising and doing nothing else except a timer for the LED flashing, so I'm not sure what could...
HI
I am using the customized nRF52832 board with a temperature sensor connected via i2c .Firmware i merged the ble_app_uart and twi_sensor xample code. Here the RX AND SDA...
Hi everyone,
I've written a custom BLE service with two characteristics. I want to write more that one bytes to one of the characteristics and then to store the written...
Hello,
I'm working with nRF52840 and SDK v15.2.
I implemented an USB layer with CDC and MSC classes based on nRF examples. All seems to work fine. The USB Serial port...
Hi,

Hi,
This is not a ticket!
This is a project that I built. It uses the nRF52 to control a neopixel (ws2812b) via I2S over BLE using a custom mobile app built using the...
On SDK16.0.0 + Mesh SDK 4.1.0
I know that oversampling when using the SADDC in scan mode on multiple channels does not work because the buffer gets all out of order.
But...
Hi,
as describe in the title, we are getting a mesh assert when trying to remove all suscibtions from a model.
it is kind of hard to reproduce because this command is...
Hello,
I am testing direction finding over nRF5340 PDK.
I didn't have antenna array yet, but I think that's equivalent to signal received at 90 degree.
I have two questions...
