看来你需要的是蓝牙门面。下面是关于蓝牙一些命令,可能会对你有所帮助:
bluetoothAccept
bluetoothActiveConnections
bluetoothConnect
bluetoothDiscoveryCancel
bluetoothDiscoveryStart
bluetoothGetConnectedDeviceName
bluetoothGetLocalAddress
bluetoothGetLocalName
bluetoothGetRemoteDeviceName
bluetoothGetScanMode
bluetoothIsDiscovering
bluetoothMakeDiscoverable
bluetoothRead
bluetoothReadBinary
bluetoothReadLine
bluetoothReadReady
bluetoothSetLocalName
bluetoothStop
bluetoothWrite
bluetoothWriteBinary
checkBluetoothState
toggleBluetoothState
要调用这些命令,你会做这样的事情
import android
droid = android.Android()
#call your commands with droid.bluetoothcommand
droid.bluetoothDiscoveryStart()
#or
droid.toggleBluetoothState(True)
下面是一些蓝牙的例子功能,它包含在SL4A中,但为了清晰起见,我添加了注释:
import android #for bluetooth functions
import time #for waiting
#get everything setup
droid = android.Android()
#turn on bluetooth
droid.toggleBluetoothState(True)
#ask user
droid.dialogCreateAlert('Be a server?')
droid.dialogSetPositiveButtonText('Yes')
droid.dialogSetNegativeButtonText('No')
droid.dialogShow()
#get user response to question
result = droid.dialogGetResponse()
#if the result is 'Yes' ('positive') then is_server is set to True
is_server = result.result['which'] == 'positive'
if is_server:
#so if is_server is true make the device discoverable and accept the next connection
droid.bluetoothMakeDiscoverable()
droid.bluetoothAccept()
else:
#attempts to connect to a device over bluetooth, the logic being that if the phone
#is not receiving a connection then the user is attempting to connect to something
droid.bluetoothConnect()
if is_server:
result = droid.getInput('Chat', 'Enter a message').result #Gets a message to send
#via bluetooth
if result is None:
droid.exit() #exit if nothing is in the message
droid.bluetoothWrite(result + '\n') #otherwise write the message
while True: #receives a message
message = droid.bluetoothReadLine().result
droid.dialogCreateAlert('Chat Received', message)
droid.dialogSetPositiveButtonText('Ok')
droid.dialogShow()
droid.dialogGetResponse()
result = droid.getInput('Chat', 'Enter a message').result
if result is None:
break
droid.bluetoothWrite(result + '\n')
droid.exit()
最后,要查看蓝牙命令的完整列表,请查看http://code.google.com/p/android-scripting/wiki/ApiReference并向下滚动到蓝牙门面。祝你好运!
@Mathew,SL4A BT api是否支持扫描其他BT设备?我没有找到该API,有没有一种方法来包含该API并构建?谢谢, V – vik86 2013-10-28 19:40:52
不幸的是,我不这么认为,我几乎不是专家,尽管如此,让我知道,如果你看到任何东西! – 2013-11-16 04:05:24
