What is the expected behavior?
ML307检测波特率正常，并能发送AT命令连接网络
What is the actual behavior?
ML307很容易卡在检测波特率上面，手上有一批无名星智的板子。之前有测试1.6.0到现在的1.6.5，烧录最新固件之后还是非常容易碰到这个现象，反复重启也没有用。 (14472) Ml307AtModem: Detecting baud rate... I (15632) Ml307AtModem: Detecting baud rate...

有什么办法优化供电吗？
当模组在4G网络最大发射功率下工作时，现网下的瞬态工作电流能达到2A，并可能引起电源电压跌落。 在任何情况下，需保证模组电源电压保持在3.4V以上，否则模组可能出现重启等意外状况。为了保持电压稳定，还需要给VBAT并联2个220微法的电容。
具体请看ML307硬件设计手册，Power部分。
