关于MicroPython开发 ESP32-S3遇到的问题
各位老师好!近期想用MicroPython在ESP32-S3硬件平台开发"蓝牙透传功能",下面是我写的代码,我是参考官方手册来写的(bluetooth — 低级蓝牙 — MicroPython中文 1.17 文档),但是跑到ble.send() 的时候会报错 ,请大家帮忙看看,感谢!
另外还有个小问题:我在开发ESP32-S3的时候,不知道 当前版本的固件,能够支持哪些Micropython模块, 有时候就发现同样的程序 1.20.0 版本不能运行,1.19.0版本又可以运行, 不知道MicroPython固件版本的差异点在哪,我要如何参考当前版本进行开发?球球了,救救孩子吧

补充一下: 环境用的Thonny ,ESP32-S3 版本是1.20.0, 球球了 帮顶。 报的什么错，最好上传源文件不要复制粘贴。 庄永 发表于 2023-7-14 12:03

已经解决了, send方法里面,要带参数1 , 而不是0 , 语法没错
