遇到了个很奇怪的问题。相同代码，正常情况下，ESP8266向电脑传输速率为100~200KB/s左右，但是
只要我用大拇指同时接触WiFi模块上的PCB天线和顶盖，ESP8266向电脑传输速率可以非常容易的突破1MB/s，峰值达到1.2MB/s以上，速度奇稳无比
以上“问题”稳定复现 =。=
我想请问下有没有方法可以使其能稳定达到？

* We add this function to force users to set rf cal sector, since

* sector map for last several sectors : ABBBCDDD
* A : rf cal
* B : at parameters
* C : rf init data
* D : sdk parameters
* Parameters : none
