That's not trivial in the general case. Doubling the stack for all examples looks like a good first step.

Btw. part of the large stack usage results from being single-threaded and switching context from stack to app and back and so forth. The newer(ish) btstack_run_loop_execute_on_main_thread would allow to defer some maintenance work, which would also reduce the needed stack space. This needs to be added file by file, so no promises here, but feel free to ping us some time in the future.
