nimble on ESP32

发表于 分类于 阅读次数： 评论数：

从好友Yufeng那里得知Nimble有在ESP32上落地，刚好手头有一片ESP-WRCOM-32，手痒痒就download了一份ESP32的IDF 玩下。
Getting Start 写的真心不错，简单明了，照着操作步骤一步一步跑就能跑起来Nimble的example project。不过ESP32只用了Nimble的Host，没有用Controller的部分，毕竟ESP32是Combo chip，Nimble Controller Scheduler没有考虑过Wifi的部分。

  • ESP32文档很很赞，花了大力气做宣传，内容挺丰富，也很正规，YouTube也有很多教学视频。
  • 还挺开放，放了不少源码出来，包括ble mesh等。
  • 不知道为啥没有自己的Host，之前用bluedroid，footprint没啥优势。
