问题描述
我正在尝试订阅 BLE 设备上的单个特性。使用 bleak 我能够连接到设备，然后写入/订阅特性。通过使用 pygatt 的几乎相同的代码，我可以使用我的 BLED112 加密狗连接到同一设备，但无法写入/订阅相同的特性。
bleak 测试程序：
import sys
import os
import asyncio
import aioconsole
from bleak import BleakClient
ADDRESS = '28686572-5A71-435E-952A-6F4292F5B04A'
#ADDRESS = '00:55:DA:B7:98:9C'
CHaraCTERISTIC_UUID = '273e0003-4c4d-454d-96be-f03bac821358'
if len(sys.argv) == 3:
ADDRESS = sys.argv[1]
CHaraCTERISTIC_UUID = sys.argv[2]
def notification_handler(sender,data):
"""Simple notification handler which prints the data received."""
print("{0}: {1}".format(sender,data))
async def run(address):
async with BleakClient(address) as client:
await client.connect()
print("Is connected")
# start notifications on control characteristic
await client.start_notify('273e0001-4c4d-454d-96be-f03bac821358',notification_handler)
# write to control handle,set preset to 21
await client.write_gatt_char('273e0001-4c4d-454d-96be-f03bac821358',bytearray([0x04,0x70,0x32,0x31,0x0a]),False)
# write to control handle get device info
await client.write_gatt_char('273e0001-4c4d-454d-96be-f03bac821358',bytearray([0x03,0x76,False)
# write to control handle for resume
await client.write_gatt_char('273e0001-4c4d-454d-96be-f03bac821358',bytearray([0x02,0x64,False)
# start notifications on TP9
await client.start_notify('273e0003-4c4d-454d-96be-f03bac821358',notification_handler)
# wait for input
await aioconsole.ainput('Running: Press a key to quit')
await client.stop_notify('273e0003-4c4d-454d-96be-f03bac821358')
if __name__ == "__main__":
os.environ["PYTHONASYNCIODEBUG"] = str(1)
loop = asyncio.get_event_loop()
loop.run_until_complete(run(ADDRESS))
输出：
$ python3 bleaktest.py
Is connected
13: bytearray(b'\x08{"rc":0}\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00')

从输出中可以看出，由于响应句柄，写入成功。考虑到控制特性和次要特性的响应，订阅显然是有效的。
pygatt 测试程序：
import pygatt
import time
from binascii import hexlify
from pygatt.backends.backend import BLEAddresstype
def handle_data(handle,data):
"""
handle -- integer,characteristic read handle the data was received on
raw_value -- bytearray,the data returned in the notification
"""
print(hexlify(data))
#adapter = pygatt.GATTToolBackend('hci0') linux backend
adapter = pygatt.BGAPIBackend()
try:
adapter.start()
device = adapter.connect('00:55:DA:B7:98:9C',address_type = BLEAddresstype.public)
print("Is connected")
# start notifications on control characteristic
device.subscribe('273e0001-4c4d-454d-96be-f03bac821358',callback = handle_data,wait_for_response = True)
# write to control handle,set preset to 21
device.char_write('273e0001-4c4d-454d-96be-f03bac821358',wait_for_response = True)
# write to control handle get device info
device.char_write('273e0001-4c4d-454d-96be-f03bac821358',wait_for_response = True)
# write to control handle for resume
device.char_write('273e0001-4c4d-454d-96be-f03bac821358',wait_for_response = True)
time.sleep(5)
# subscribe to eeg characteristic
device.subscribe('273e0003-4c4d-454d-96be-f03bac821358',indication = False,wait_for_response = True)
time.sleep(5)
finally:
print("Adapter stopped")
adapter.stop()
输出：
$ python3 pygatttest.py
Is connected
Adapter stopped
pygatt 程序能够连接到设备（我可以看到指示灯状态从闪烁变为常亮），但订阅失败。我不知道 char_write 是否有效，因为我没有收到退货通知。我正在尝试使用 logging 模块根据下面的评论找出更多信息。
已启用 logging 的更新输出：

我不确定我是否正确解释了这些信息，但似乎订阅正在工作并且我正在接收信息但没有触发回调？
我在这里尝试了解决方案：pygatt: Unable to execute device.subscribe() 通过将 time.sleep() 行添加到我的代码中，但输出没有改变。
如何将我的 bleak 程序翻译成 pygatt 并使用 pygatt 成功订阅？
