EC200S's firmware version

Hi Quectel support team.
I have two batches of EC200S modules with firmware versions EC200SCNAAR01A09M16 and EC200SCNABR03A05M16. Could you please let me know whether they have the same hardware, and which firmware version is newer?

Please also send me the latest firmware.

You can send it to me at hohuydai@ginno.com.
Thanks
