这边是因为切到legacy后，对端发了a2dp start 虽然是silence data, 但我们这边会建立sniffing/recovery link,并把adv停掉，主耳能连上是因为gfps的广播还开着.

耳机和phone B配对 不连附耳的原因是附耳没有enable le audio广播，请帮忙看看是否和recovery link有关

目前b2s link number是2， mtc_db.device.max_conn_num也是2，code就走到 mtc_terminate_cis()了
|
||
|
||
|
||
|
||
**解决办法：**
|
||
|
||
**<span style="color: rgb(23,43,77);">MTC_MAX_LINK_NUM目前是2</span>**
|
||
|
||
<span style="color: rgb(23,43,77);">将 MTC_MAX_LINK_NUM改成4</span>
