S2-LP / FKI433V2 is receiving garbage data from 433Mhz ASK Manchester Encoded 9.6KBaud transmitter using S2-LP DK GUI.

 I have tried setting the MANCHESTER_EN register and a huge combination of data rates etc in order to get some sensible data in the S2-LP GUI, but nothing is consistent or representative of the data I expect to see.I can see the data correctly using ...

So the details of the configuration are: i am using I2C3 peripheral with the clock speed of 100kHz the pins are set to open drain no pull up no pull down. I am also using external pull up ressistors.I have already checked the internet for a solution ...
