DLPNIRNANOEVM: DLP Nanoscan controlled by ESP32 - What data to send?

I'm communicating with the NIRscan nano evm over UART by sending and receiving commands.

I'm able to send commands to put the lamp on and off, get the device status, ...

So I'm able to send en receive commands.

The next thing to do is to receive the files which are stored on the SD card. 

But I'm struggling with sending the proper 'data' in the command. 

First, I wan't to perform the 'Read file list size' command over UART. 

The user guide says that it needs 1 byte for the Data Payload Input, but it is unclear for me what it should be. 

It just says 'NNO_FILE_SCAN_LIST'

Can you help me with this?
