Example of Status and Length Read Back:
●
Reading back the status byte and length (either with or without a command) can be done after
sending Header 06H and receiving ACK. Normally if sent with no command the length of available
data will be 0, and only the status byte is useful.

The Status Byte can be used to determine various sensor conditions and the Length is used with
the 0Ch command to specify the amount of data to be read in.
