How to call out Gboard virtual keyboard through bluetooth?

I use Gboard on my android phone. I'm developing a software working on bluetooth barcode sanner. When my barcode sanner connected with my phone via bluetooth HID protocol, the Gboard virtual keyboard will be hidden. I want to call out Gboard virtual keyboard by sending some commands through bluetooth HID protocol. What the command should I send through bluetooth HID protocol?
