Hi, Gurus! Newbie to Odoo here...

I'm using Odoo Online, have a Sunmi D2S Combo POS machine with a built-in Bluetooth POS receipt printer. Entire system runs on custom Android, i.e., Sunmi OS v2.0.

Scenario:

The OS test prints perfectly fine to the built-in BT printer. But I am unable to find resources on how to get Odoo POS to print to this built-in printer.

• I've tried checking/unchecking "ePOS Printer" option in the "Point of Sales" > "Configuration" > "Settings" under "Connected Devices". I have no idea on the IP address because it is a built-in printer. Hence, I just left the IP address empty but with "ePOS Printer" option checked. I've tried it with the IP address of the POS machine but it doesn't print either.
• I've also tried using the "IoT Box" but have been unable to detect any devices so I presume Sunmi D2S Combo POS machine is not an "IoT Box".

I've tried this on Loyverse POS, and it prints the receipt fine because it has "Sunmi" in the list of printers.

Help on identifying the BT receipt printer will be much appreciated. Thank you in advance!
