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.

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...
This is both a general tip for users and a question; does anyone have good success with the LIS2DH12 double-tap feature? The 3-axis accelerometer works well but the use of...
Hi, I'm using nrf51 without ble.
I want to update flash but not want to delete PAGE every time.
NRF_NVMC->ERASEPAGE = (uint32_t) page_address;
How can i do?
We use IOS DFU toolbox to upgrade firmware with BLE device. we can upgrade successfully with Android, but always failed with IOS.
wrong code is: DFUErrorReadingVersionFailed...
Hi, it's probably a very dumb question, but i don't seem to find any details about it. In nrf52 SDK documentation, in Error Module section it says
The behavior of the...
Hi friends...!
I want to put dynamically changing MPU data into the advertising packet. I am putting my accelerometer data into manufacturer specific data field of ble_advdata_t...
How robust is the output PA of the nrf905?
Assume the ouput matching network and 50Ohm connector is used as in the 868Mhz application note.

Hi,
I am using s130v2 and running the example code from: nRF5_SDK_12.3.0_d7731ad\examples\ble_peripheral\ble_app_hrs\pca10028\s130\arm4
This is the only modification I...
Hi,
I know this is a Bluetooth 5 spec question, but wanted to know the practical figures for current consumption when nrf52840 is used as both central and peripheral...
Hi,
We are expecting many of our devices to be in close proximity. How can we be certain that when a user initiates a buttonless DFU, that they are uploading to the correct...
Hi,
I thought central is the one which fills up its look up table with 16 bit IDs to keep track of the peripherals. If multiple devices can act as central at the same time...
I am trying to re-base my SDK package, and when I started off with the ble_app_template project for the pca10040 s132, I copied my main file on top, everything compiles just...
I am developing an application which involves control of a brushed DC motor with a quadrature encoder. According to this post, in SDK 12.2.0 - which I am using - it is possible...
