bluetooth-lowenergy - 使用 WiFi 时停止 BLE

Question

我正在尝试在 ESP32 上使用 BLE 和 WiFi。正如我所见，它们不能同时使用，所以我试图找出一种方法来停止从 BLE 服务器接收数据。这是我迄今为止尝试过的停止 BLE 的方法：

btStop();
esp_bt_controller_disable();
esp_bluedroid_disable();

然而，似乎没有一个工作。ESP32 应该连接到 WiFi（使用 WiFiManager），但是当我尝试连接到 Firebase 或 Twilio 时，连接被拒绝。在尝试连接到 Firebase 之前，我有 35000 个空闲堆和 twilio 80000。那么，有没有办法检查 BLE 扫描/连接是否已停止？是否有任何其他命令可以将其关闭？可能是我的堆用完了，因此我无法连接到 Firebase？

Answer 1

You're currently missing a couple of deinit calls

esp_bluedroid_disable();
esp_bluedroid_deinit();  //**
esp_bt_controller_disable();
esp_bt_controller_deinit(); //**

You might also have to ensure Wi-Fi hasn't been started while BLE was enabled, you can init, but starting might cause issues where it starts trying to use the radio immediately

Answer 2

如果您使用的是 BLEDevice 库，请尝试以下操作：

 BLEDevice::deinit(true);
