BM64麦克风输入是否有可能自动切换发生

我尝试将MIC输入连接到BM64模块中，以在电话呼叫期间测试从A2DP配置文件到HFP/HSP的开关的声音质量，并在MIC（作为对讲机模式）拾取噪声的情况下，判断是否有可能自动切换发生。E硬接线模块上的一个面包板（附），以获得一个工作原型，但在芯片上没有地方，我可以找到端口TP1和TP3如建议的参考电路图（也附上）。我的下一步是如何让音频进入芯片，这样它就可以被电话另一端的接收器听到？对此事的任何帮助都将得到极大的感谢。

    I'm trying to connect a mic input into the BM64 module to test the sound quality of the switch from an A2DP profile to an HFP/HSP during a phone call, and to gauge whether or not it's possible for auto-switching to occur as soon as noise is picked up by the mic (as an intercom mode).

Currently, we're hardwiring the module onto a breadboard (Attached) to get a working prototype, but nowhere on the chip can I find the ports TP1 and TP3 as suggested by the reference circuit diagram (Also attached). What should be my next step for getting audio into the chip so that it can be heard by a receiver on the other end of the phone?

Any help on this would be greatly appreciated.

Thanks

Tommy
