Hello,To be security complaint, I need to propose a secured Bluetooth connection between a MC75 and a Bluetooth printer to print payment receipts: crypto + authentication + printing failure management.

I’been told BT mode 3 could be part of the solution. Do we implement it, do we have best practices?

David, Yes it’s the standard Bluetooth encryption the user can leverage from BluetoothExplorerMenu->Settings->Security and check the box “Encrypt Link On All Outgoing Connections” Taheer

Below are the options to make the BT transaction secure: 1. Make sure MC75 BT is not discoverable 2. Use PIN authentication so that remote BT printer becomes a trusted device 3. Use encryption when sending data to the printer. Taheer
