When I compare the EV2300's commands to the bq40z60 to that listed in the technical reference manual I don't quite understand what is going on.
for example, the technical manual says to read chem ID you send (Command: 0x44, Data: 0x 06 00) but what actually sends is (0x 44 02 06 00 12) .
I've come to understand that the second value when sending commands indicates the length of what you're sending. In the example above it is 2 because 06 00 are the two bytes. When I read blocks like 0x71 it will tell me there are 32 values to follow. Am I also to presume that the last byte is some sort of parity byte for the system? It changes with every unique command, which makes me feel like that's what this is.
I'm wondering for when I send my own commands to the bq40z60 through a microcontroller or host of some sort, will I also need to include these extra bytes that aren't mentioned in the technical reference manual?
