Preface
In Ubuntu systems, Bluetooth debugging is often required. The following introduces how to use a Bluetooth adapter (CSR8510).
系统 ：Ubuntu 16.04
python3 版本 : python3
USB2.0蓝牙适配器 ：CSR8510
1. Bluetooth adapter
1. Bluetooth adapter identification
- Plug in the hardware, open a terminal and see if the device is detected:
╰─➤ lsusb
Bus 001 Device 003: ID 203a:fffa
Bus 001 Device 002: ID 203a:fffa
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 002: ID 203a:fff9
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 002 Device 003: ID 203a:fffe
Bus 002 Device 002: ID 203a:fffc
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
- Check whether it is recognized as a Bluetooth module:
╰─➤ hciconfig -a

- View the address of the Bluetooth module:
╰─➤ hcitool dev
Devices:
hci0 00:1A:7D:DA:71:13
2. Bluetooth adapter activation
- When debugging BLE devices, you need to obtain root permissions.
#设备打开蓝牙
sudo hciconfig hci0 up
#设备关闭蓝牙
sudo hciconfig hci0 down
2. bluepy test
1. bluepy installation
1. 安装libbluetooth-dev
sudo apt-get install libbluetooth-dev
2. 安装bluepy
sudo python3 -m pip install bluepy
说明：本次安装bluepy 版本为 1.3.0 ，可通过指令查看
ls /usr/local/lib/python3.5/dist-packages
2. bluepy test
- Scan demo.py as follows:
# #!/usr/bin/python
# -*- coding: UTF-8 -*-
import requests
import os
import tempfile
import errno
import sys
import binascii
import unittest
import warnings
import argparse
import time
from bs4 import BeautifulSoup
from binascii import hexlify
from time import gmtime, strftime, sleep
from bluepy import btle
from bluepy.btle import Scanner, DefaultDelegate,UUID, Peripheral
class ScanDelegate(DefaultDelegate):
def __init__(self):
DefaultDelegate.__init__(self)
def handleDiscovery(self, dev, isNewDev, isNewData):
if isNewDev:
print("Discovered device", dev.addr)
elif isNewData:
print("Received new data from", dev.addr)
class NotifyDelegate(DefaultDelegate):
def __init__(self):
DefaultDelegate.__init__(self)
def handleNotification(self, cHandle, data):
print("Notification from Handle: 0x" + format(cHandle,'02X') )
print(hexlify(data))
def ScannerDevice(devices,devAddr):
for dev in devices:
if dev.addr==devAddr:
targetDev = dev
print("扫描到目标设备: %s" %(dev.addr))
print("---------------")
print("Device %s (%s), RSSI=%d dB" % (dev.addr, dev.addrType, dev.rssi))
for (adtype, desc, value) in dev.getScanData():
print(" %s = %s" % (desc, value))
if dev.addr==devAddr:
print("停止继续扫描")
print("---------------")
break
if __name__ == '__main__':
addr = "00:17:c7:9c:2f:6b"
scanner = Scanner().withDelegate(ScanDelegate())
devices = scanner.scan(10.0)
ScannerDevice(devices,addr.lower())
print("总共扫描到 %d 设备" %(len(devices)))
- Get Bluetooth Mac address:
1. 安卓系统可通过指令获取：
adb shell settings get secure bluetooth_address
22:22:F4:FA:0E:00
2.其他目标设备自行查找：
当前测试设备蓝牙Mac : 00:17:c7:9c:2f:6b
- Execute demo.py:
sudo python3 scan.py
- As shown in the following log, you can view the scanned device information:
╰─➤ sudo python3 demo.py
