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...
Hello,
I'm using nRF52840 and nRF Connect. I've customized hello_world sample from Zephyr to also work with mcumgr and receive and respond to SMP commands such as "echo...
Hi,
I have been using an UART connection for serial communication but it stops working when I enable the Bluetooth module and initialize it. The error I receive is the same...
Hello, in an effort to downsize the EC2 instance from t3.small to t2.micro (nrfcloud-mqtt-bridge/MqttBridgeCluster/DefaultAutoScalingGroup), the bridge instance is detached...
I have adapted and incorporated the NCS OTA DFU sample into my project. Initially, FOTA updates have been working. Now, after pushing an update, the image is stuck pending...
Hi,
We are making software for our custom board based on nRF52833 and nRF5 SDK 17.0.2. We use app_uart for our serial communication in active mode and in sleep mode we disable...
I'm trying to build a basic shell sample on a custom board based on nRF52840
In the proj.conf file I have
CONFIG_SHELL =y
CONFIG_SHELL_GETOPT =y
CONFIG_SHELL_BACKENDS...
I am new to Zephyr and I have been trying to get hold of a tutorial or a sample app that would indicate how I can use the UART on the nRF52832 for communications with another...
Hi,
I'm wrapping up a project which uses an nRF5340 as both a Bluetooth peripheral to advertise etc and also as a Bluetooth central to scan for devices (not both at the...
I recently started development on NRF52833 for one of my projects. I use segger embedded studio with the " ble_app_uart " example. As I mentioned I'm using nrf52833 DK so...
I want to recover DFU over BLE upon a dropped connection while in the middle of an update.
I have my own software that I've cooked up to program from another NRF52 chip...
Hi,
I see you have what appears to be a working implementation of OOB/NFC pairing over iOS here ( https://github.com/NordicSemiconductor/IOS-Nordic-Thingy ), which doesn...
Hello! We have an application that I need to implement Tensorflow Lite. We started with the Arduino Nano 33 BLE Sense board, which had a TFL library on it. After using it...
Hi,
For 52820-QDAA, what load impedance is preferred seen into the matching network? I mean the total load impedance of C3, L1, C4, L2, RF trace and antenna.
Since our...
In our application, we've enabled full modem firmware update, which requires us to enable CONFIG_NORDIC_SECURITY_BACKEND. When we also enable memfault, this compile time pre...
I am build an application with features : When I not used nRF it imediately in sleep mode and be wake up by BLE events to send some text, and return to sleep mode ( the reson...
