jnius是一个Python库,可以在Python中调用Java代码。这个错误说明在使用Bluetooth连接时读取数据出现了问题,可能是由于连接被关闭或超时。可以尝试重新连接并检查连接状态,确保连接正常打开。另外,也可以尝试使用不同的Bluetooth库或升级至最新版本以解决这个问题。以下是一个Python代码示例,展示了如何使用“jnius”库来连接Bluetooth设备和发送数据:
from jnius import autoclass
BluetoothAdapter = autoclass('android.bluetooth.BluetoothAdapter')
BluetoothDevice = autoclass('android.bluetooth.BluetoothDevice')
BluetoothSocket = autoclass('android.bluetooth.BluetoothSocket')
adapter = BluetoothAdapter.getDefaultAdapter()
device_address = '00:11:22:33:44:55' # replace with the MAC address of your device
device = BluetoothDevice.createTypedRfcommSocketToServiceRecord(device_address)
# connect to the device
device.connect()
# send some data
output_stream = device.getOutputStream()
output_stream.write(b'hello world')
# disconnect from the device
device.close()
