使用6843AOP蓝牙模式，具体如下
1，通过python写了一个脚本来接收蓝牙数据，如下，开始的时间才0.1s级别，之后就1-2s级别，导致不能及时接收到数据（即表现为不能接收到每一帧的数据），导致这样的原因是什么
python脚本程序如下
import asyncio
import binascii
import bleak
import time
async def run():# 定义你的 Simple Peripheral 设备的 UUID 和 characteristic UUIDsimple_peripheral_uuid = "58:53:03:B8:93:85"characteristic_uuid = "0000fff1-0000-1000-8000-00805f9b34fb"# 创建一个缓冲区来存储接收到的数据data_buffer = bytearray()# 连接到 Simple Peripheral 设备async with bleak.BleakClient(simple_peripheral_uuid) as client:while True:start_time = time.time() # 记录开始时间# 读取 characteristic 的值value = await client.read_gatt_char(characteristic_uuid)hex_value = binascii.hexlify(value).decode('utf-8') # 将16进制数据转换为十六进制字符串print(f"Received data: {hex_value}, Timestamp: {time.time()}")# 计算数据接收的时间间隔end_time = time.time()time_diff = end_time - start_timeprint(f"Time interval: {time_diff}")
loop = asyncio.get_event_loop()
loop.run_until_complete(run())
输出如下：

2，通过连接AOP的帧来接收蓝牙的输出数据，用TTL转USB的串口器连接下图的RX，TX，接收到的数据是连续的，即可以接收到每一帧的数据
Galaxy Yue：
您好，
1.增加缓冲区的太小，可以减少接收数据的时间间隔
将data_buffer()的大小从bytearray（）改成bytearray（1024）试试
2.可以用pygatt 或 bluepy 其他蓝牙库试一试
