使用CYW20706怎么实现最大化连接数

我使用CYBT-34 3026-EVE板连接到许多BLE传感器，并通过GATT读取数据。我的代码是基于示例SNIP/BL/GATTYDB的。我想连接尽可能多的传感器，在理想情况下，最多应该连接16个传感器。
每个传感器每秒用小的有效载荷发送100个关贸总协定通知。当我连接到多个传感器时，一些传感器的吞吐量每秒低于100个通知，有时低至每秒25个通知。我试着用参数Chan-Min区间和Con Max间隔来处理。见下表我的结果。对于这些测试，Max同时链接被设置为8。
ConnMin InValConnect Max In ValuRealTuts66可以连接到6个传感器，没有问题。之后的第六个传感器连接我可以不再扫描新的sensors.88i可以连接8个传感器，但有时一个传感器的吞吐量下降。这个问题是由连接的传感器，最后connected.1616i不能连接4多个传感器没有至少一sensor.3232i获得吞吐量的损失不能连接超过4传感器没有至少一sensor.6464i获得吞吐量的损失不能超过4固定连接没有至少一个传感器获取的吞吐量损失传感器。
我怀疑的问题是一个重叠的传输窗口，使一些通知要失去。另一个传感器（因此设置一个新的发射窗口）有时解决问题。设置固定的发送窗口长度可以解决该问题。
我有几个问题：
有一个固定的限制的cyw20706芯片可以设置BLE设备连接数？有没有设置固定发送窗口长度的方法？你有哪些参数会影响在wiced_bt_cfg_settings_t连接设备的数量有没有其他的建议？

  I am using a CYBT-343026-EVAL board to connect to many BLE sensors and to read data from them via GATT. My code is based on the example snip/ble/gatt_db. I would like to connect to as many sensors as possible, in the ideal case up to 16 sensors should be connected.

Every sensor sends 100 GATT notifications per second with a small payload. When I am connected to multiple sensors the throughput of some sensors drops below 100 notifications per second, sometimes as low as 25 notifications per second. I have tried to fiddle around with the parameters conn_min_interval and conn_max_interval. See the table below for my results. max_simultaneous_links was set to 8 for these tests.

6	6	I can connect to 6 sensors with no problems. After the sixth sensor is connected I can no longer scan for new sensors.
8	8	I can connect to 8 sensors, but sometimes the throughput of a sensor drops. This issue is fixed by reconnecting the sensor that was last connected.
16	16	I can't connect more that 4 sensors without getting throughput losses for at least one sensor.
32	32	I can't connect more that 4 sensors without getting throughput losses for at least one sensor.
64	64	I can't connect more that 4 sensors without getting throughput losses for at least one sensor.

I suspect that the problem is an overlapping transmit window that causes some notifications to be lost. Reconnecting one sensor (and therefore setting a new transmit window) sometimes fixes the problem. Setting a fixed transmit window length may fix the problem.

I have multiple questions:

• Is there a fixed limit to the number of connections the CYW20706 chip can set up to BLE devices?
• Is there a way to set a fixed transmit window length?
• Do you have any other suggestions which parameters in wiced_bt_cfg_settings_t may affect the number of connected devices?
