Hi there,
The EC200A-CN contain many other models, pls query the current version of your module via ATI command and we will provide you the correct latest FW, thank you.

Hi Duncan, my current fw is EC200ACNHAR01A03M16. I would like to upgrade fw by FOTA because i have soldered module on board. Pls help me check !

Hi there,
We support DFOTA function on R01A04 version, so you could not update via FOTA cause your version is R01A03. You can update via USB port and the FW will send you via email, pls check your email, thank you.

Hi Duncan, my board does not have USB test point for USB fw upgrade. Can i connect wire directly to USB pin on module to flash fw ? Pls give me a hardware connection guide to do it. Many thanks !

You need to fly these four pins out, and then connect to the PC for upgrade, thank you.
