树莓派4与ESP32基于BluePy的BLE频繁断开问题求助

我最近碰到了一个非常棘手的BLE通信问题：树莓派4作为BLE中心端（客户端）连接ESP32外设端（服务端）时，连接极不稳定，但用安卓手机的nRF Connect应用连接ESP32时却全程稳定，这说明问题肯定出在树莓派本身或者我的代码逻辑上。

具体表现是：初始BLE连接能正常建立，也能成功读取特征值，但在随机次数（通常1-50次）的读取操作后，连接必然会断开。目前我使用的是BluePy 1.3.0版本，系统是全新刷入的Raspbian镜像。

以下是我的核心代码：

import time
from bluepy.btle import Peripheral

peripheral_address = "8c:aa:b5:85:20:1e"
service_uuid = "537e7010-9928-4595-89dc-46b495862dc6"
characteristic_uuid = "3778ceab-0974-4eb0-9da5-26c3a69cc742"

# Read from peripheral
p = Peripheral(peripheral_address, "public") #random does not work!!
Service=p.getServiceByUUID(service_uuid)
Characterization=Service.getCharacteristics(characteristic_uuid)[0]
print("Got characterization")
time.sleep(1)

while True:
    value = Characterization.read()
    print(value)
    time.sleep(0.1)

连接断开时抛出的错误回溯信息：

Traceback (most recent call last):
  File "/home/pi/Desktop/BLETest/bleRead.py", line 16, in <module>
    value = Characterization.read()
  File "/usr/local/lib/python3.7/dist-packages/bluepy/btle.py", line 197, in read
    return self.peripheral.readCharacteristic(self.valHandle)
  File "/usr/local/lib/python3.7/dist-packages/bluepy/btle.py", line 530, in readCharacteristic
    resp = self._getResp('rd')
  File "/usr/local/lib/python3.7/dist-packages/bluepy/btle.py", line 407, in _getResp
    resp = self._waitResp(wantType + ['ntfy', 'ind'], timeout)
  File "/usr/local/lib/python3.7/dist-packages/bluepy/btle.py", line 362, in _waitResp
    raise BTLEDisconnectError("Device disconnected", resp)
bluepy.btle.BTLEDisconnectError: Device disconnected

我尝试过添加异常捕获逻辑来处理断开后的重连，但不仅没解决根本问题，反而引发了更多未知错误，而且重连的耗时还会导致关键数据丢失。有没有具备树莓派客户端稳定BLE通信经验的开发者能给我一些可行的解决方案？非常感谢！
