Hi, it's no problem over 255 size.
Old Particle(Spark/Photon, and Arduino) TCP stack firmware have some buggy, can't send large data with some problem. So I commited "MQTT_MAX_PACKET_SIZE 128" on first version of this library. And I thought sensors don't send big size data at once.
But now, it's stable and can send bit size. And more I think MQTT_MAX_PACKET_SIZE is dependent on MTU(Photon TI CC3000 MTU = 1468byte), so MQTT_MAX_PACKET_SIZE can up to about 1400.
