With pullup resistor I get sendDone event, also if with Fail error but
I think it is because I have not yet connected a slave device that
answers with an acknowledge signal.
Thanks a lot to everybody for the help.

SDA has a pullup, SCL does not and requires a pullup for I2C mode.

I think so. ;^) The good folks at MoteIV have the schematic for the TMote
Sky in the data sheet, and on a cursory glance I don't see pull-ups. This
actually makes sense, since the I2C and SPI busses share pins, and if not
running I2C there's no good reason for pullups on those lines.
