It is possible that you might be reprogramming the receiver and sender with
different MESSAGE_LEN values. Also did you change the size of the default
packet size? it is 41 hence for using 100 you will need to change the value
by providing a line as below in the makefile.
CFLAGS += -DTOSH_DATA_LENGTH=114
