ble和5ghz wifi怎么同时使用

我们使用BCM433芯片,并通过WICE 3.7.0~7实现蓝牙连接的过程。在该部分的数据表中,在第115页,它指出“BCM4340不提供同时2.4 GHz和5 GHz的操作”。由于BLE被放置在芯片的2.4GHz部分,这个陈述是否意味着如果使用5GHz AP来进行WiFi接入,那么BLE就不能使用?

  We use a BCM43340 chip and are in the process of implementing bluetooth connection through WICED 3.7.0-7.  In the datasheet for the part, on page 115, it states that "The BCM43340 does not provide simultaneous 2.4 GHz and 5 GHz operation".  Since the BLE is housed in the 2.4GHz portion of the chip, does this statement mean that BLE cannot be used if using a 5GHz AP for wifi access?

你的理解是正确的。数据表和示意图似乎表明,如果使用5 GHz AP用于WiFi接入,则不能使用BLE。验证这一点的一种方法是测试BLYWiFixIdvor应用程序,在那里连接到5 GHz AP并检查连接是否被维护。

我在内部检查了WiFi组合芯片产品团队,它似乎所有我们目前的组合设备(如CYW4345和其他)利用分立PHY,MAC和共享天线,所以5GHz的无线局域网和2.4GHz的BT同时是可能的(即5G SwiTAP与BLE)。
我们有一个设备,今年晚些时候,可以利用一个双天线路径和LNA,这将是最佳的2.4GHz无线局域网和同时BT。
记住,原来的问题是同时引用5GHz WLAN和2.4GHz BT,而不是2.4GHz WLAN和5GHz无线局域网——这只有RSDB才可能。
希望这有帮助。

I checked internally with the WiFi Combo chip product team and it appears that all of our current combo devices (ex. CYW43455 and others) leverage a seperate PHY, MAC and shared antenna, so 5GHz WLAN and 2.4GHz BT simultaneously is indeed possible (i.e. 5G softAP with BLE).
 
We have a device coming out later in the year which can take advantage of a dual antenna path and LNAs, and this will be optimal for 2.4GHz WLAN and simultaneous BT.
 
Remember though that the original question references 5GHz WLAN and 2.4GHz BT simultaneously – not 2.4GHz WLAN and 5GHz WLAN – that’s only possible with RSDB.
 
Hope this helps.
