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

Hi, I have the same error.My IDF is 4.1, and the phone is Redmi 6,the system is Android 9. 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。

Re: ESP32 OTA via BLE

hi,
I'm doing related BLE OTA functions. Has anyone made any suggestions ? Now I am looking at the DFU of Nordic to find some solutions.

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?

Re: Ble mesh provisioner

是的,我从ble_mesh_fast_prov_server demo 代码中找到如你所说的自定义实现方法。我猜测vendor model没有统一的标准,所以各个厂家的做法都不一样?我目前正在把ble_mesh_fast_prov_client demo 按照手机provisioner配置流程去修改,当前已可以实现esp32 vendor model client 和nordic vendor model server通讯了。目前ble_mesh_fast_prov_server 存在vendo rmodel client和server,有没有必要实现ble_mesh_fast_prov_cl...

Re: Ble mesh provisioner

你好,我找到原因了。ble_mesh_fast_prov_client demo provision ble_mesh_fast_prov_server demo的实现过程和手机不一样。ble_mesh_fast_prov_server demo在收到ESP_BLE_MESH_MODEL_OP_APP_KEY_ADD opcode时,一并把model的配置自己做好了,并没有像手机provisioner那样进行发送ESP_BLE_MESH_MODEL_OP_MODEL_APP_BIND opcode 把 model APPkey绑定,发送ESP_BLE_MESH_MODEL_OP_MODEL_P...
