Hello,
As far as I can tell, the NUS app sends a signed char of value -127 to 127 in decimal. Is there a way to use the stock UART application to send an unsigned byte...
Hi Noridic,
I follow the Application note Nan_36 and download the nrf51-ble-app-lbs project as a practice, but the compiling is not smoothly with SDK 9.0. I finally fix the...
Hello,
I am working with S110 stack and the custom application. I wanted to use the ADC driver with blocking and interrupts enabled. But the application is blocking and...
Hi, I use NUS quite alot with the following condition;
(SDK 7.2 & S110 7.1 with IAR 7.1)
When the peripheral only uses NUS, iOS cannot detect the peripheral at the ...
Naive follow up to What is NUS? .
Is NUS merely a vehicle for tutorials and fast prototyping? Or can it be used to build real world apps on?
If so, do we rename the...
Hi All,
We are in design phase of our project . We would like to use NRF52832 for our project.
Our project is a wearable based on BLE. We are planning to use RTOS in NRF52...
I am starting to port the example
