I’m writing a script which calls a C library and the program is just stopping prematurely with no output.
How do I debug this?
A little context:
I’m passing a Julia function as a callback to the SimpleBLE C library that is called when data is received from a Bluetooth device. The callback is called once and seems to execute successfully and a few seconds later the process stops.
The callback contains an unsafe_wrap to read the incoming data, then calls println to display it and finally calls the library’s free function on the received data.
