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 support team,
In my case, i want to auto disconnect to ble central after some minutes with no message transfered, so i create an timmer and set event compare and clear...
We are developing a beacon with nrf52810. We test ble_app_beacon example and a modified example( the difference is, advertising packets are connectable to be applicable in...
I've configured UART2 on the nRF9160 to connect to a nRF52840. The nRF52840 generates a payload and sends it over to the nRF91. The payload size during testing was 65 bytes...
Hello,
I am developing using nrf2840 PDK, SDK v17.0.0, S140
I have made two services, one is to control the led blinking rate via nrf connect android app and the other...
Hi,
Is it possible to have dual transport for DFU (UART and OTA)?
I read this in the forum: https://devzone.nordicsemi.com/f/nordic-q-a/28118/multiple-dfu-transports ...
I have nRF52840 as the central and nRF52832 as the devices. I have the device names as TELCO_456, TELCO_457, TELCO_458 in the connectable advertisement packet. I have disabled...
I am trying to capture sniffer logs for a custom BLE peripheral using nRF51 dongle and Wireshark. I am following this guide here to install the Sniffer tool in Wireshark....

Hi,
I'm running of the fw-nrfconnect-nrf master branch (commit: 96e75dba598320c2707dede3ffef44bf326a89e3) because there are some improvements since the release of SDK v1...
Hi,
I am developing a custom device with nrf52840 and use SPI for flash driver and radar sensor.
For better SPI performance of the flash driver and radar sensor, I am...

Has anyone been able to connect the nRF52 to MATLAB using their new Bluetooth Low Energy Communication interface ( https://www.mathworks.com/help/matlab/bluetooth-low-energy...
Why is "No location data available" always printed when SUPL data is downloaded in gps sample app? This happens at any place. I guess this causes a long TTFF.
This is a...
Hello. I have a DK nRF9160 0.8.2 version. I am sending AT command through UART with an external MCU (STM). I am interested on evaluating power consumption during an UDP packet...
