To disconnect from the paired Bluetooth device, press and hold the Power/pairing button on your speaker for one prepaid gift balance.

You have also change option in menuconfig, disable Secure simple pairing (or enable).

Secure simple pairing (disabling this throws error for esp_bt_gap_set_pin )
i added the code from link as below,
is it right ?

Code: Select all

    case ESP_SPP_INIT_EVT:
        ESP_LOGI(SPP_TAG, "ESP_SPP_INIT_EVT");
        esp_bt_dev_set_device_name("bt_server");

	esp_bt_pin_type_t pin_type = ESP_BT_PIN_TYPE_FIXED;
	esp_bt_pin_code_t pin_code;
	pin_code[0] = '0';
	pin_code[1] = '0';
	pin_code[2] = '0';
	pin_code[3] = '0';
	esp_bt_gap_set_pin(pin_type, 4, pin_code);


        esp_bt_gap_set_scan_mode(ESP_BT_CONNECTABLE, ESP_BT_GENERAL_DISCOVERABLE);
        esp_spp_start_srv(sec_mask,role_slave, 0, SPP_SERVER_NAME);
        break;

I have bt classic project i finished 2 days ago and now checked to make sure. You have to disable
Secure simple pairing
to make use of static pin code.

Thats strange, because those flags are already there:
https://github.com/espressif/esp-idf/bl ... g.defaults

Maybe try to use idf.py defconfig.
