BaracodaPencil 2 is a wireless data capture product.

This document is detailing the protocol of communication between the Baracoda scanner Pencil2

and its foreign environment through Radio Frequency link (ie: Bluetooth).

The protocol of communication does not depend on the type of link.

Wireless communication is based on the Bluetooth protocol, thanks to the embedded Baracoda

Equinox Bluetooth Stack.

The messages described in this document can be:

Host to scanner messages: the packet is sent only by the host to the scanner

Scanner to host messages: the packet is sent only by the scanner to the host

Bidirectional messages: the packet format is the same whether it is sent by the host or the scanner

All the frames described in this document are formatted as shown:

Code ID

Length

Payload

1 Byte

2 Bytes

N Bytes

- 1 byte for code ID

• Bits 7:5 is the logical device

• Bits 4:1 is the command

• Bit 0: when set, the message must be acknowledged

- 2 bytes for the size of the payload (big-endian), including the sequence number byte which is

considered as part of the payload

- Payload (including 1 byte for sequence number when applicable).

The response will have the same code ID as the command.
