I am trying to find the flow chart for the findme program by analyzing the source code files.
I was wondering what does "__enable_irq() " do in the source code main_cm4.c file?
Here, I don't see any declaration for interrupts

Indeed, you don't see any declaration for interrupts. But, bluetooth radio subsystem use own interrupt handler.
You can see it on Find Me Project , Design Wide Resources → Interrupts.
Out of device reset, all interrupts are disabled and interrupt priorities are set to zero.

Liviu Dogaru,
I was wondering if there is a detailed similar file for Psoc6 BLE prototyping kit with device CYBLE-416045-02.?
if so can you please share it?
