# Milestone 16: Virtual Hardware - Bluetooth
|
||||
|
||||
**Status**: Complete
|
||||
**Goal**: Bluetooth discovery and pairing with user consent.
|
||||
|
||||

|
||||
|
||||
## Overview
|
||||
|
||||
This milestone implements secure Bluetooth access for Lua apps:
|
||||
- Discovery requires user consent (user gesture)
|
||||
- Permission required: `bluetooth` for discovery and connection
|
||||
- Device info limited to name and address (no UUIDs)
|
||||
- Connection limit: 5 active connections per app
|
||||
- Automatic cleanup on app stop
|
||||
|
||||
### Key Deliverables
|
||||
|
||||
1. **BluetoothInterface class** - Bluetooth discovery and connection management
|
||||
2. **BluetoothConnection class** - Individual connection handling
|
||||
3. **Lua bluetooth API** - `bluetooth.startDiscovery()`, `bluetooth.connect()`
|
||||
4. **Privacy protection** - Limited device information, user consent required

|

### 2. Permission and Consent Requirements
|
||||
|
||||
| Action | Permission Required | User Consent Required |
|
||||
|--------|--------------------|-----------------------|
|
||||
| Start Discovery | `bluetooth` | Yes (user gesture) |
|
||||
| Connect to Device | `bluetooth` | No (implicit from discovery) |
|
||||
| Send Data | `bluetooth` | No (connection already established) |
|
||||
| Receive Data | `bluetooth` | No (connection already established) |
|
||||
|
||||
### 3. Privacy Protection
|
||||
|
||||
Device information is limited to:
|
||||
- Device name (display name)
|
||||
- Device address (MAC)
|
||||
|
||||
NOT exposed:
|
||||
- Full UUID list (prevents service fingerprinting)
|
||||
- Device class
|
||||
- Manufacturer data
|
||||
- RSSI (prevents proximity tracking)
|
||||
|
||||
### 4. Lua API
|
||||
|
||||
```lua
|
||||
-- Start device discovery (requires user gesture)
|
||||
bluetooth.startDiscovery(function(devices)
|
||||
for _, device in ipairs(devices) do
|
||||
print("Found:", device.name, device.address)
|
||||
end
|
||||
end, function(error, message)
|
||||
print("Discovery error:", error, message)
|
||||
end, {
|
||||
timeout = 30 -- seconds
|
||||
})
|
||||
|
||||
-- Stop discovery
|
||||
bluetooth.stopDiscovery()
|
||||
|
||||
-- Check if discovering
|
||||
local discovering = bluetooth.isDiscovering()
|
||||
|
||||
-- Connect to a device
|
||||
local conn = bluetooth.connect(address, function(data)
|
||||
print("Received:", #data, "bytes")
|
||||
end, function(error, message)
|
||||
print("Connection error:", error, message)
|
||||
end, {
|
||||
timeout = 10000 -- ms
|
||||
})
|
||||
|
||||
-- Check connection
|
||||
if conn and conn:isConnected() then
|
||||
-- Send data
|
||||
conn:send({0x01, 0x02, 0x03})
|
||||
|
||||
-- Get connection info
|
||||
print("Connected to:", conn:getAddress())
|
||||
print("Connection ID:", conn:getId())
|
||||
end
|
||||
|
||||
-- Close connection
|
||||
conn:close()
|
||||
|
||||
-- Get active connection count
|
||||
local count = bluetooth.getConnectionCount()
|
||||
|
||||
-- Disconnect all
|
||||
bluetooth.disconnectAll()
|
||||
```
|
||||
|
||||
### 5. Error Codes
|
||||
|
||||
```lua
|
||||
-- Error values passed to error callbacks
|
||||
"PERMISSION_DENIED" -- No bluetooth permission
|
||||
"USER_CONSENT_REQUIRED" -- User gesture required for discovery
|
||||
"DISCOVERY_FAILED" -- Discovery could not start
|
||||
"CONNECTION_FAILED" -- Could not connect to device
|
||||
"NOT_CONNECTED" -- Connection not established
|
||||
"CONNECTION_LIMIT" -- Max connections reached (5)
|
||||
"TIMEOUT" -- Operation timed out
|
||||
"ALREADY_DISCOVERING" -- Discovery already in progress
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Test Cases
|
||||
|
||||
### Test 1: Requires Permission
|
||||
|
||||
```cpp
|
||||
bool Test_BluetoothRequiresPermission(std::string& error_msg) {
|
||||
mosis::BluetoothInterface bluetooth("test.app");
|
||||
// No permission granted
|
||||
|
||||
std::string err;
|
||||
bool started = bluetooth.StartDiscovery(
|
||||
{},
|
||||
[](const std::vector<mosis::BluetoothDevice>&) {},
|
||||
[](mosis::BluetoothError, const std::string&) {},
|
||||
err
|
||||
);
|
||||
|
||||
EXPECT_TRUE(!started);
|
||||
EXPECT_TRUE(err.find("permission") != std::string::npos);
|
||||
|
||||
return true;
|
||||
}
|
||||
```
|
||||
|
||||
### Test 2: Requires User Consent
|
||||
|
||||
```cpp
|
||||
bool Test_BluetoothRequiresUserConsent(std::string& error_msg) {
|
||||
mosis::BluetoothInterface bluetooth("test.app");
|
||||
bluetooth.SetBluetoothPermission(true);
|
||||
// User consent NOT granted
|
||||
|
||||
std::string err;
|
||||
bool started = bluetooth.StartDiscovery(
|
||||
{},
|
||||
[](const std::vector<mosis::BluetoothDevice>&) {},
|
||||
[](mosis::BluetoothError, const std::string&) {},
|
||||
err
|
||||
);
|
||||
|
||||
EXPECT_TRUE(!started);
|
||||
EXPECT_TRUE(err.find("consent") != std::string::npos ||
|
||||
err.find("gesture") != std::string::npos);
|
||||
|
||||
return true;

|
||||
|
||||
EXPECT_TRUE(started);
|
||||
EXPECT_TRUE(got_devices);
|
||||
EXPECT_TRUE(discovered.size() == 2);
|
||||
EXPECT_TRUE(discovered[0].name == "Device A");

### Test 4: Connection Limit
|
||||
|
||||
```cpp

|
||||
EXPECT_TRUE(conn != nullptr);
|
||||

|
||||
}
|

|
||||
// 6th should fail
|

auto extra = bluetooth.Connect("AA:BB:CC:DD:EE:FF", {}, err);
|

EXPECT_TRUE(extra == nullptr);
|
||||
EXPECT_TRUE(err.find("limit") != std::string::npos);
|

|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
All tests must pass:
|
||||
|
||||
- [x] `Test_BluetoothRequiresPermission` - Permission required
|
||||
- [x] `Test_BluetoothRequiresUserConsent` - User consent required for discovery
|
||||
- [x] `Test_BluetoothDiscoveryWorks` - Discovery returns devices
|
||||
- [x] `Test_BluetoothConnectionLimit` - Max 5 connections enforced
|
||||
- [x] `Test_BluetoothSendReceive` - Send/receive data works
|
||||
- [x] `Test_BluetoothCleansUpOnShutdown` - Cleanup on shutdown
|
||||
- [x] `Test_BluetoothLuaIntegration` - Lua API works
|
||||
|
||||

|
||||
|
||||
## Dependencies
|
||||
|
||||
- Milestone 1 (LuaSandbox)
|
||||
- Milestone 2 (PermissionGate + user gesture tracking)
|
||||
|
||||

|
||||
|
||||
## Notes
|
||||
|
||||
### Desktop vs Android Implementation
|
||||
|
||||
For desktop testing, BluetoothInterface operates in mock mode:
|
||||
- Discovery returns mock device list
|
||||
- Connections track state but don't communicate
|
||||
- Send/receive can be simulated for testing
|
||||
|
||||
On Android, the real implementation would:
|
||||
1. Use BluetoothAdapter via JNI
|
||||
2. Handle BLUETOOTH_SCAN and BLUETOOTH_CONNECT permissions
|
||||
3. Use BluetoothSocket for RFCOMM connections
|
||||
4. Support BLE via BluetoothGatt
|
||||
|
||||
### Security Considerations
|
||||
|
||||
1. **Permission required**: `bluetooth` permission needed for all operations
|
||||
2. **User consent**: Discovery requires active user gesture
|
||||
3. **Limited device info**: Only name and address exposed (no UUIDs)
|
||||
4. **Connection limit**: Max 5 connections per app
|
||||
5. **Cleanup**: All connections closed when app stops
|
||||
|
||||
### Privacy Features
|
||||
|
||||
1. **No service UUIDs**: Prevents detailed device fingerprinting
|
||||
2. **No RSSI**: Prevents proximity tracking
|
||||
3. **User consent**: Discovery requires explicit user action
|
||||
4. **Audit logging**: All Bluetooth operations logged
