频谱分析仪在启动时显示不需要的传输是怎么回事？

问题在于，该模块在启动过程中显示大量不需要的传输，导致FCC认证失败。


如附件所示，传输是意外的，不在 FCC 规定范围内。根据 FCC 的规定，不允许在蓝线之外传输。

> Even deleted every WiFi SDK link, without success

> Tried different power supplies, no success
> The phenomenon is also visible during a restart from deep sleep
> After restart, so from the first line of the initialization/setup(), I have full control without issues.

目前，我不知道如何解决这个问题。我希望这是 ESP 硬件问题，但不确定。
