I2C at low speed put out wrong data

Hi all,

I am using KL15, and  I am trying to use I2C with very low data rate (2kHz, I am using EE893 sensor), but when I send data in output, the data is wrong (I must send 0x71 as address, and i see on the oscilloscope 0x7F) and after a numbers of retrasmission, nothing go out!  When I set the speed at 100kHz, the data in output is correct and it doesn't stop after a number of retrasmission!

 

Can you help me?

Thanks

Marco
