undefined reference to esp_blufi_gap_event_handler

[glrtheil]

After more digging i know what is the problem and it is a bug, which should be reported. The problem is that one of header files is not C++ compatible. You can "fix" it in you code like this:

Code: Select all

extern "C" {
#include "esp_blufi.h"
}

Unfortunately, after adding that to either my class header or cpp file, it doesn't make a difference. No errors on the include itself, but UC_BT_BLUFI_ENABLE and BLUFI_INCLUDED are still undefined.

Like i said, UC_BT_BLUFI_ENABLE and BLUFI_INCLUDED are in esp-idf private headers, so if you dont want to change bt component it is what it is. The code with extern "C" will let you build and run app with blufi, thats all.

Thanks for the help with this one. In the end I abandoned the c++ class I had built for blufi, and did all the blufi stuff in c. It integrates well with the rest of our c++ stuff.

oh dear... Another 6 hours wasted...

Has someone submitted an issue for this?
