CCS/EK-TM4C129EXL: wrong I2C communication with MOD1016(Sensor: AS3935) lightning module

Part Number: EK-TM4C129EXL

Tool/software: Code Composer Studio

Hey guys,

 
We recently ordered a MOD1016(Sensor: AS3935) lightning module to detect lightning. 
 
We are trying to communicate with the sensor using our TI µC board EK-TM4C129EXL using I2C bus.
 
According to the data sheet we have to communicate with the sensor as it is shown on this protocol on the screenshot. 
 
 

 
 
We don't know how to call the repeated start and we are not sure what to send before and after the repeated start.
 
Which command do we have to use in order to create a repeated start? (is it burst or single)
 
Is this a common problem? Do you happen to have any tips how we could solve this?
Below you can find an extract of our code. 
 
We appreciate any kind of help. 
Many thanks!
