usb_cdc_4g_module工程存在问题，在使用手机连接wifi时，会发生重启。！！！！

Postby linshc » Wed May 11, 2022 2:33 pm

描述：使用ESP-IDF4.4.1，4G模组使用EC600NCNLA-N05。编译成功，烧入成功，ppp成功并获取到了DNS，wifi-ap模式启用成功，并在手机上能搜索到该wifi热点。但连接该热点时，成功率非常低。
问题1：在使用手机连接该wifi热点时，模块发生重启。

我使用的板子为ESP32S2，出现上述情况的概率很大。想请教一下如何解决这个问题？

第一个 RESET 原因是 POWERON。请检查供电是否有问题，4G 模组峰值电流 2A，WiFi 峰值电流 500mA，在 WiFi 连接时，可能电源无法满足要求，导致硬件重启

第二个原因，需要等问题一已解决再跟进
