esp32 deep sleep 唤醒后如何快速恢复与路由器的连接

你好,
我目前在做低功耗的一个应用。由于esp32和wifi路由器的连接过程比较慢,如果esp32在deep sleep唤醒后需要重新发起路由器连接,所以想请教下,esp32有没有提供快速恢复与路由器连接的功能?

esp32 低功耗deep sleep 如何存储WiFi连接状态

我目前有一个应用是deep sleep睡眠唤醒后能维持wifi的连接,不需要重新连接路由器。在规格书上有写deep sleep低功耗模式下可以存储wifi的连接信息。但是我找不到相关的接口和实现。请问下这个wifi连接信息具体指哪些数据?如果说在睡眠之前保存IP连接信息,在唤醒后能直接导入这些IP连接信息维持上一次的路由器连接吗?

安卓手机无法正常配对esp32蓝牙

我最近在大量进行手机测试。目前测试到华为P20,红米6手机在进行密码配对时,设备使用 public addr,第一次配对成功后,如果设备删除绑定关系,重新进行连接配对时就再也连不上,更奇怪的是,即使手机进行删除绑定关系也连不上了,除非设备MAC进行修改。手机表现出来的现象是,有提示进行配对的弹框,但是输密码的弹框没有出现,导致无法继续配对。设备端出现的错误日志如下 lld_pdu_get_tx_flush_nb HCI packet count mismatch (0, 1) E (432523) BT_BTM: Device not found 。而且在这种情况下,多次进行连接后,会造成程序...

Re: BLE - ESP_GAP_BLE_PASSKEY_NOTIF_EVT not seen with certain Android phones

My phenomenon is that for the first time, the connection can be normally paired, and then the device can no longer connect after deleting the binding information.So is this a bug for IDF or the phone? Can anyo...

配对过的IOS13.5的手机无法连接删除绑定信息的esp32蓝牙

你好,我的IDF版本是4.1,手机是IOS13.5版本的,APP是nRF Connect。
当IOS手机配对连接esp32蓝牙成功后,把esp32本地存储的蓝牙绑定信息删除掉,IOS手机就没办法再次连接了,会提示“Peer removed pairing information”,然后断开。除非用户手动在手机蓝牙设置里把手机本地的设备绑定信息删除后,才能再次配对连接。
目前我测试到IOS11,IOS12版本的手机不会出现这种情况。

你好,这是我的sdkconfig和之前的错误日志。目前板子在客户那里,你说的Debug模式日志打印得晚点

ESP32-D0WD-V3 芯片启动失败

你好,
我IDF 版本是4.1,之前代码成功运行在ESP32-SOLO-1模组上,现在换模组ESP32-WROOM-32E,发现这款模组的芯片类型是ESP32-D0WD-V3。我按照ESP32 ECO V3使⽤指南去配置Minimum Supported ESP32 Revision 选项为 “Rev 3”。结果代码运行不了,具体错误用IDF监视器解析出来为下图,我不清楚还需要哪里参数配置?
