Previously, I designed a PCB for the nRF52832 chip using the RFANT3216120A5T antenna ( link ). However, I was only able to achieve a very limited Bluetooth range of around...
Hi, I'm relatively new to Nordic microcontrollers and have recently completed the beginner's course. Sorry in advance if I made an obvious mistake.
I am currently trying...
We are running a nrf54l15 board that uses an NFC T2T tag to encode a URI to open an application. We have noticed that sometimes, the current stays higher (~200 uA) after the...
I’ve got a bit of a hardware issue with the nRF52811 UART, receiving DMX data from a Chinese DMX controller.
Standard DMX data-rate is 250Kb/S, so the minimum bit time is...
Hi,
I am using the Nordic UART Service (NUS) peripheral and central on two nRF52840 DKs and I am developing with nRF Connect SDK v3.0.0 .
I can't manage to increase the...
I am getting an occasional softdevice assert on a BLE central device (hub). Both the central and peripheral devices are nRF52840 using Coded PHY and NCS v2.7.0. This error...
I am trying to keep nRF5340 in sleep state, and wake it up when there's a user input (e.g., button) and send a packet as fast as possible to iOS18. What would be the latency...
Hi,
I am trying to implement buttonless DFU by following the ble_app_hrs example provided in the SDK and modifying the bootloader (nRF51_SDK_10.0.0\examples\ble_peripheral...
We have our custom PCB design that we program and debug by connecting the SWD lines to nrf51 DK's SWD. We wanted to use trace for better debugging options, however we discovered...
Hi,
I have a task to do PWM frequency repeater on nrf52832. After reading forums I decided to make it with PPI, 2 GPIOTE and 3 Timers. Here what I did: https://github...
Hello everybody,
I used SDK14.2 S132
I defined fds_write and read function like that;
Also, I wrote a function to register particular data;
Then I used save_data...
Hi, I followed through this tutorial:

But to my frustration I realized...
Deer friends,
The nRF Connect BLE app supports the configuration of the local device's GATT attribute table, also known as server setup. Adding attributes to the server...
Hi
I am researching options for my bachelor project which happens to be about bluetooth 5, where I am looking to develop a smartlighting system using Bluetooth 5 mesh....
Hello Nordic Support!
We are making a prototype that connects the battery to Vcc, but 5 out of 10 It works properly. Conversely, the remaining five do not behave as expected...
Dear friends,
In the Power Profiling Application (an example of nordic SDK), the priority of the application timer is set to APP_LOW(as shown in the pic below).
However...
stdio.h defines vsprintf and _vsprintf, and suggests using _vsprintf if you want to save on code space.
extern _ARMABI int _vsprintf(char * __restrict /*s*/, const char...
As per the Bluetooth Spec (v5.0) Page 2323-2324, it seems that LE Secure connections pairing supports 1-way OOB. See section of text below.
If OOB communication is possible...
Once GPIO is pressed (shorted to ground), I want to change the value of UUID or Major/Minor number
If not, the device will continue to advertise the previous values
Hello,
I am working on a custom project with nRF52832 using SDK14.2 and s132_nrf52_5.1.0.
Now I am trying to configure and use RTC2, and face the problem that ble_stack_init...
Hello everyone,
after hours of python module installation, I was able to run the PPK with PCA10056. I have cut the SB40 and used an external pwoer source with 2,5 V. I have...
