Fixed use of CONFIG_BLUEDROID_ENABLED instead of CONFIG_BT_ENABLED in HAL. This prevented compilation with Nimble-only configuration without apparent benefit.
* Update esp32-hal-bt.c
BluetoothSerial crash when restart: this is because the BT controller remains in state ESP_BT_CONTROLLER_STATUS_INITED instead of state ESP_BT_CONTROLLER_STATUS_IDLE after the end() method.
in file esp_bt.h it is specified
> @brief Enable BT controller.
> Due to a known issue, you cannot call esp_bt_controller_enable() a second time
> to change the controller mode dynamically. To change controller mode, call
> esp_bt_controller_disable() and then call esp_bt_controller_enable() with the new mode.
after **esp_bt_controller_disable()** the controller remains in state INITED so we do call the **esp_bt_controller_deinit()** function to put the controller into state IDLE.
i have modified the **esp32-hal-bt.c** file
line 57 and next
(i have insert the esp_bt_controller_deinit() function so the controller go into Idle state)
```c++
bool btStop(){
if(esp_bt_controller_get_status() == ESP_BT_CONTROLLER_STATUS_IDLE){
log_i("bt stopped");
return true;
}
if(esp_bt_controller_get_status() == ESP_BT_CONTROLLER_STATUS_ENABLED){
log_i("bt enabled");
if (esp_bt_controller_disable()) {
log_e("BT Disable failed");
return false;
}
while(esp_bt_controller_get_status() == ESP_BT_CONTROLLER_STATUS_ENABLED);
}
if(esp_bt_controller_get_status() == ESP_BT_CONTROLLER_STATUS_INITED){
log_i("inited");
if (esp_bt_controller_deinit()) {
log_e("BT deint failed");
return false;
}
while (esp_bt_controller_get_status() == ESP_BT_CONTROLLER_STATUS_INITED);
return true;
}
log_e("BT Stop failed");
return false;
}
```
