Reuse (static) OSCBundle

[tttapa]

I would like to reuse an OSCBundle object, because I don't want to keep blocking the entire loop while waiting for a SLIP message.

The first bundle works, but all successive bundles give an error. I get the same result with a static OSCBundle, local to loop, or a global OSCBundle

Here's a short program that demonstrates this problem:

#include <OSCBundle.h>

void setup() {
  Serial.begin(115200);
  while (!Serial);
}

const uint8_t data[] = {
  0x23, 0x62, 0x75, 0x6E, 0x64, 0x6C, 0x65, 0x00,  //  #bundle·
  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,  //  time = 0
  0x00, 0x00, 0x00, 0x18,                          //  size = 24
  0x2F, 0x74, 0x72, 0x61, 0x63, 0x6B, 0x2F, 0x31,  //  /track/1
  0x2F, 0x6D, 0x75, 0x74, 0x65, 0x00, 0x00, 0x00,  //  /mute···
  0x2C, 0x66, 0x00, 0x00,                          //  ,f··
  0x00, 0x00, 0x00, 0x00                           //  value = 0.0
};

void muteHandler(OSCMessage &msg) {
  Serial.println("Mute");
}

auto getOSCErrorName(OSCErrorCode error) {
  switch(error) {
    case OSC_OK: return F("OSC_OK");
    case BUFFER_FULL: return F("BUFFER_FULL");
    case INVALID_OSC: return F("INVALID_OSC");
    case ALLOCFAILED: return F("ALLOCFAILED");
    case INDEX_OUT_OF_BOUNDS: return F("INDEX_OUT_OF_BOUNDS");
  }
}

// OSCBundle bundleIN;  // doesn't work
void loop() {
  // OSCBundle bundleIN;      // works
  static OSCBundle bundleIN;  // doesn't work

  bundleIN.fill(data, sizeof(data)/sizeof(*data));

  if (!bundleIN.hasError()) {
    bundleIN.dispatch("/track/*/mute", muteHandler);
  } else {
    Serial.print("Error: ");
    Serial.println(getOSCErrorName(bundleIN.getError()));
  }
  bundleIN.empty();
  delay(2000);
}

Output:

Mute
Error: INVALID_OSC
Error: INVALID_OSC
...

As you can see, the first iteration correctly dispatches the mute message, but all successive bundles give an INVALID_OSC error.

How can I resolve this?

Found it. Add this line:
decodeState = STANDBY;
to this function:
OSCBundle& OSCBundle::empty()
