Introduction

In this chapter, we will provide low Level API’s which can be used to develop software that is compatible with BitGuard. BitGuard uses connectivity over USB or BLUETOOTH, In this section we will describe API’s using BLUETOOTH communication channel. Same API’s can be used for USB. The type of protocol used between device and BitGuard is Universal Asynchronous Serial Communication. First we will describe how to initialize the device and confirming the integrity of BitGuard

Overview

Commands Brief Description

Command	Name	Description
0x00	Initialize	Used to initialize BitGuard
0x01	Get Address	Used to get public Address of the coin
0x02	Get Public Key	Used to get public key of a coin
0x03	Initialize transaction	Used to initialize transaction signing
0xff	Reset	Used to terminate a process

Above mentioned commands will be in HEX.

Buffer Sizes

Mode	Buffer Size
BLE	20 Bytes
USB	1023 Bytes

Command Format

Commands mentioned in table above will be in HEX (1 byte). Commands other than these commands will have start byte as ‘<’ (ASCII : 60) and stop byte as ‘>’ (ASCII : 62).

Note

These API’s are meant to be used only by developers and not users. Using them without permission of Blockwala will void the warranty of the device.
