I am trying to get a good handle on the difference in average power consumption between BLE point to point and Zigbee on an nRF52840. We have battery powered products and...
Hi, For my project, I need to design a BLE packet sniffer which scanning the 40 channels. Therefore, I need 40 dongles are connected to a computer that can read and transfer...
I am writing code to get a nrf52840 DK to associate with an existing 802.15.4 coordinator using the 802.15.4 API module within SDK 15.2.
I've called "mlme_scan_req" and...
Currently, I am able to use Mqtt Publisher or Subscriber with only one Nrf52 device. I can ping to the device with link-local address.
I am using Nrf52832 with SoftDevice...
Hi everyone,
After days of figuring out how CMake works, I try to write a CMakeList.txt myself, and decide to put my progress on this community. Right now, using CLion with...

Hello everyone,
as indicated by this question https://devzone.nordicsemi.com/f/nordic-q-a/35692/adding-nrf52-dk-to-github-mesh-demo-for-thingys/138327#138327 I am trying...
Hi
Regarding the NFC url example there is any way to change the URL dynamically. My idea is to, at a certain point, be able to modify the URL configured during the setup...
Hello,
I'm having an issue when trying to update the bootloader itself: NRF_UICR->NRFFW[1] returns 0xFFFFFFFF, which means I can't use the MBR command to swap bootloaders...
Our BLE product uses a meander PCB antenna similar to PCA10031. It works actually quite fine, but a question pops up when it comes to tuning.
Antenna matching design in...
I'm having some issues getting the auto ACK to work properly. I am only receiving auto ACK messages on the first 3 received packages, after which the receiver stops replying...
Hello i have a system that build in an ultrasonic sensor RedBearLab BLE Shield ( nrf8001 ) and arduino i want to get ultrasonic data via bluetooth and see it on nRFConnect...
Hi,
My host MCU controls nRF51 over SWD interface.
How can stop/halt nRF CPU? After initialization the SWD(init/read DB/AP AHB, etc.) I need to halt (stop nRF program...
Hi,
I would like to have one page of flash mapped manually to store information critical for the device. Let's assume I do not trust data preserving by DFU or there is...
I have some BLE traffic that I have sniffed and am displaying in Wireshark. Most of the opcodes (read/write request/response indications/notifications etc.) are parsed/displayed...
I am trying to develop a GATT service on nRF51.
The GATT service measures a few values, and stores them in a characteristic. When the GATT server (phone) requests data...
I am trying to build a device to stream the 9 axis sensor data from the I2C based sensor and then transmit it using BLE UART profile. It is sampled every 3 seconds using app...
I am using an nrf51422 board. I want to update via OTA using ANT+ Dongle. The device information shown in the OTA Updater is parsed from the Bootloader Code. Is there any...
Hello!
I want to connect the MCP9808 with the nrf52832. Therefor I use i2C.
My example on the nrf52832 is the:
<nRF5_SDK_v11_0_0 folder>\examples\ble_peripheral\experimental_ble_app_eddystone...
We're quite interested in producing an nRF52 design based on the solar beacon (great design, and clean software). I appreciate the relative simplicity and manageable BOM cost...
Hello,
I am developing a system that samples 3 independent data using SSADC. since the timing was important in my system, I decided to use PPI to trigger the SSADC.
However...
