Introduction
1.1.
1.1.1.1.
1.1. Generalities
The Plug&Scan solution enables a simple, reliable and efficient use of its compatible barcode readers
(the whole Baracoda product range) thanks to Bluetooth. The RS232 version allows the connection
on any RS232 enabled terminal.
The dongle allows a simple and secure Bluetooth connection: just scan the « connect barcode » (on
the dongle) and the scanner gets connected and ready to operate.
The dongle is compatible with the whole product range, and with a certain number of them, is able
to automatically configure them after the connection.
The messages described in this document can be:
Host to dongle messages: the packet is sent only by the host to the dongle
Dongle to host messages: the packet is sent only by the dongle to the host

Depending on the selected code ID the payload length may vary (from to 65535 bytes), its length is
specified on the 2 bytes of the « length » field.

For the « get » commands, no payload is required since the dongle responds with the requested
data. The specified length in the « length » field is then and no byte constitute the payload. When
the sent command is a « set » command, the dongle parses and treats the command if its format is
correct but does not answer.

All the commands described in this document can also be sent via Bluetooth thanks to a Baracoda
