No, from another one.
The thread that run the io_service simply runs it:

void io_worker_thread(void)
{
  io_service.run();
  std::cout << ">>> io_service.run() TERMINATED! <<<<<" << endl;
};

ProcessRTPPacket() is a library "event" and maybe it is called from
another thread!

Mmmm...so maybe, in the other project, it worked because I called timers
into the asio::serial_port::async_read_some callback that should be
inside the io_service thread! Isn't it?

Yes, the setTimer is called, but the timer callback not!

Cheers,
