I have been trying to connect two Galileo Arduino boards over I2C following Arduino - MasterWriter. But although both master and slave codes got transferred to respective boards, I am not getting any output in the slave serial console. Moreover, when I provided some log inside the receiveEvent function in the slave code, I saw that the receiveEvent is not getting called at all. When I tried Arduino - MasterReader I faced the same issue i.e. no data transfer. Any suggestion?
