I guess it is this, in Firmata.cpp:
void FirmataClass::begin(long speed)
{
#if defined(__AVR_ATmega128__) // Wiring
Serial.begin((uint32_t)speed);
#else
Serial.begin(speed);
#endif
blinkVersion();
delay(300);
printVersion(); // <-- this!
printFirmwareVersion();
}
This function is called at startup.
So, if arduino only sends this at startup, and if startup is not
guaranteed to (re)happen when connecting to it, what is the correct way
to ensure that you send the necessary configuration messages (such as
pinMode stuff) just after opening the port? Other than putting an
arbitrary delay I mean.
If you just send the pinModes immediately after the "open" messages,
you're almost sure they're lost, but there doesn't seem to be any safe
way to be informed of when you can send them...
Any idea? Or do I have to put a few second delay and hope it is always
enough?
The "open 1" message is only triggered by sending the "info" message,
but then the same problem raises: when do I send the "info" message?
Thanks
