Hi everyone
I am trying to understand if it 's possible to change the clock frequency on-the-fly, by giving a certain command to the uC via UART.
I started from the...
I am using esb in SDK 11 and my understanding is that the radio causes interrupts that are forcing and cannot be disabled. These in turn causes software interrupt 10 to be...
Hello,

I guess the answer is yes, because I know Characteristic Declaration (UUID 0x2803) has an unique handle for each characteristic.
Just wanted to confirm.
Its the first time I use simple_timer. I do not use the Softdevice. So I'm working with the peripeheral simple_timer example(SDK11).
I know from the app_timer, that every...
Hei!

Hello,
I find in your source code contradictory values for the UART TX and RX characteristics.
E.g. have a look at nRF toolbox (both Android and IOS) definitions: github...
