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.

Thanks that solved it, i had to manual insert following code, i was getting error on compilations,

Code: Select all

#define CONFIG_CLASSIC_BT_ENABLED 1
#define CONFIG_BT_SPP_ENABLED 1

i found from this comment https://github.com/platformio/platform ... -475671300

Thanks @chegewara you always provide right and accurate information.
Keep doing best work. Take care

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

Maybe try to use idf.py defconfig.

I'm not sure about setting a static pin, but as far as discover-ability timeout, you would edit /etc/bluetooth/main.conf and set DiscoverableTimeout = 0 and you might also want to change PairableTimeout = 0.
