I think the maximum will be 256. It is because according to TEP 111 the length field is one byte long. However, in practice you might not be able to send packets that long because of RAM constraints. By default it send packet of payload length 28. You can increase it by setting TOSH_DATA_LENGTH at compile time. I suggest do not change it at runtime but only compile time. In your application Makefile add CFLAGS += -DTOSH_DATA_LENGTH=110 to increase length to 110.
