Re: 在哪里能下载到早期的ESP32技术规格书v3.6。需要ESP32 D2WD的资料。

Hi,
请参考附件规格书。请注意旧版规格书中一些内容可能已经在新版规格书中更新,ESP32-D2WD 以外的内容建议参考新版规格书。

官网的API指南只有BLUFi和BLE-MESH,没有蓝牙的介绍。
如何去学习使用蓝牙相关的API?通过例程和API参考里一个个自己琢磨?
您好,

推荐看这里面 https://github.com/espressif/esp-idf/tr ... edroid/ble 的 tutorial。另外您具体是想使用哪个例程呢?

Re: 乐鑫文档反馈问卷

你好, 我是新手,我觉得文档应该是可以找到任何有关那个开发板的资料,而不会没了寻找的路线。 好比说以下我的经历, 1) esp_bt_octet16_t dhk the 16 bits of the dh key value dh 这个缩写代表什么?查遍文档都没说。到 https://github.com/espressif/esp-idf/blob/master/components/bt/host/bluedroid/api/include/api/esp_gap_ble_api.h 也没答案。只好到别的开发板网页找。 如果有缩写表能翻查,那肯定学习起来会更快。有了容易使用又明了的文档就...

Re: full MMU/MPU documentation

Hi, Thanks for your feedback. The lowest bit of DPORT_IMMU_PAGE_MODE is indeed reserved, what the header file says is incorrect. We are going to update the MMU/MPU section in the Technical Reference Manual. Subscribe https://www.espressif.com/en/subscribe to espressif.com so you don't miss the update.
