I2C problem

I need to use I2C on a WMP100 to communicate with a microcontrolleur and read informations.
I tried the example program. The first point is when the mode is synchronous, the functions AT+READ and AT+WRITE return -2 (ADL_RET_ERR_PARAM), in asynchronous mode, this functions return 0. The second point is when I watch to the signals, they are always the same (one for write and for read) even when I change the parameters of the functions AT+READ and AT+WRITE.
If somebody tried to use I2C on WMP100, I need some help.

Thank you.

I have the same problem.
someone can give me the steps to set the bus to read or write information from a microcontroller in the correct way?
