[已解决] GATT CLIENT例程导致开发板持续重启

Postby 某某ESP32友 » Thu May 20, 2021 3:33 pm

WIN10系统,VSCODE+idf插件开发环境,IDF版本4.2.1,python3.8.9,开发板为ESP32 WROOM,编译烧录ble中的GATT CLIENT 和SERVER例程后,整板频繁掉电加电,现象就是持续听到USB口设备移除声音,此时找不到COM口,用VSCODE无法继续烧录。最后采取摁住EN键,使用烧录工具整片擦除的办法解决。
同样使用VSCODE+插件,这两个例程在原来python3.5 IDF4.0环境下无任何问题。
PS:这个问题我不理解的地方,USB不是U转串芯片CP2101负责吗,供电电路目测就是简单的ASM1117稳压芯片,就算是固件造成ESP32死机循环,是如何影响U转串芯片和电路工作的???BUG这么诡异的吗???

你插件的版本是多少?你烧录完成后,不要用 vscode 的插件里的 monitor,直接用串口调试助手呢?当出问题后,设备管理器上,COM3 还在吗?如果在的话,还能用串口调试助手连上吗?只有这两个示例有问题?还是其他简单的示例,如 blink 也会这样?

插件版本是1.0.3,应该是最新版本。
现在的状况不是例程本身运行的问题了,根据情况判断,是整个开发板在频繁的掉电加电,所以造成USB串口在不停的插拔,现象就是系统持续不断的播放USB设备移除的提示音。此时串口根本无法工作,打开串口软件也找不到USB串口。
我个人怀疑是固件BUG造成整个ESP32芯片瞬间短路,导致整个开发板供电线路重启,重启后芯片加电运行又短路,进入死循环,所以只有按住EN,使芯片停止运行,消除固件运行造成的短路,才能使USB串口正常工作,进而烧录或擦除。我认为真是这种情况,这应该算是一个芯片比较严重的硬件BUG了。

将固件奉上,可以试一下是否如此,发现这固件好大啊,启用BLE,需要这么大的固件吗?稍微整合点别的岂不要超1M了

所以先排除是 vscode 插件的问题。你是否试过其他 example?你使用的是什么开发板?

没有任何问题,请先排查你自己的开发板。

核心板是wroom32,开发板是devkitv1,是直接用烧录工具烧录到0X10000吗?

重启电脑,安装一个更新之后,问题就消失了,真是太诡异了。

居然是Micro usb接口的问题,出现类似情况,重新插拔一下,烧录完成就不会出现所描述问题,是板载的micro usb口,电脑端的USB口再插拔也没用,号神奇诡异的问题。
