Unable to open the sd card file while transmitting audio data to connected device through bluetooth a2dp (AUD-5602)

[MSalman9133]

through using example code (D:\ESP_ADF\esp-adf\examples\player\pipeline_a2dp_source_stream)

[MSalman9133]

audio_element_set_uri(fatfs_stream_reader, "/sdcard/test.mp3"); // i had set the same path still no luck

1. discovery and connection is absolutely fine when comes to transmission itself open the file is an error

[MSalman9133]

even mounted uri path also correct,read operation is also correct,when commes to open the sdcard file return -1.

Have you set menuconfig > Component config > FAT Filesystem support > Long filename support ?

Tqs for u reply hbler99 but still the same no luck

[hbler99]

You can try set Max long filename length > 512

[hbler99]

menuconfig > Component config > FAT Filesystem support > Max long filename length > 512

[MSalman9133]

if place 512 save and build the project after that also again reverting back to 255

[MSalman9133]

even i had tried smaller name (renamed test.mp3 to t.mp3) i tried with that still the same

[hbler99]

The SD card might be damaged. I recommend formatting the SD card and then trying again.

[MSalman9133]

@hbler99...? can u please share the refrenece if u have

[hbler99]

What's your development board? In my way, the button flag is set by input key service

ESP_LOGI(TAG, "[ 3 ] Create and start input key service");
    input_key_service_info_t input_key_info[] = INPUT_KEY_DEFAULT_INFO();
    input_key_service_cfg_t input_cfg = INPUT_KEY_SERVICE_DEFAULT_CONFIG();
    input_cfg.handle = set;
    periph_service_handle_t input_ser = input_key_service_create(&input_cfg);
    input_key_service_add_key(input_ser, input_key_info, INPUT_KEY_NUM);
    periph_service_set_callback(input_ser, input_key_service_cb, (void *)board_handle);

    audio_board_handle_t board_handle = (audio_board_handle_t) ctx;
    int player_volume;
    audio_hal_get_volume(board_handle->audio_hal, &player_volume);
    if (evt->type == INPUT_KEY_SERVICE_ACTION_CLICK_RELEASE) {
        ESP_LOGI(TAG, "[ * ] input key id is %d", (int)evt->data);
        switch ((int)evt->data) {
            case INPUT_KEY_USER_ID_PLAY:

                send_flag = true;
                ESP_LOGE(TAG, "START recording");
                break;
            case INPUT_KEY_USER_ID_SET:

                if (player_volume > 100) {
                    player_volume = 100;
                }
                audio_hal_set_volume(board_handle->audio_hal, player_volume);
                ESP_LOGI(TAG, "[ * ] Volume set to %d %%", player_volume);
                break;
            case INPUT_KEY_USER_ID_VOLDOWN:
                ESP_LOGI(TAG, "[ * ] [Vol-] input key event");
                player_volume -= 10;
                if (player_volume < 0) {
                    player_volume = 0;
                }

                break;
        }
    }

    return ESP_OK;
