It can only have 3 stored image in " at!image?"

That means you need to download  
SWIX55C\_03.14.10.00  
SWIX55C\_03.14.10.01  
SWIX55C\_03.14.10.04

And then switch the firmware in the field by at!impref command

See some example here:

> Yes, one by one upgrade F/W OK, But it will take a long time to upgrade, Windows 10 will waste long time to detect new device every time, and I have a lot of modules need to upgrade, so wanna upgrade 3 .cwe at a time. Thanks.
