joint work of BLE and erasing operations of flash memory

[Dimych]

Hi,
please tell me how you can solve the problem:
after BLE initialization, the esp_partition_erase_range function stops working
the program just freezes and the WDT is triggered ((
if you do not turn on bluetooth, everything works fine...
Used ESP-IDF v4.2.1 and module ESP32-WROVER-B, PSRAM enabled

    if (ret){
        ESP_LOGE(ESP_NEDAP_TAG, "gatts register error, error code = %x", ret);
        return;
    }
    ret = esp_ble_gap_register_callback(gap_event_handler);
    if (ret){
        ESP_LOGE(ESP_NEDAP_TAG, "gap register error, error code = %x", ret);
        return;
    }
    ret = esp_ble_gatts_app_register(PROFILE_A_APP_ID);
    if (ret){
        ESP_LOGE(ESP_NEDAP_TAG, "gatts app register error, error code = %x", ret);
        return;
    }
    esp_err_t local_mtu_ret = esp_ble_gatt_set_local_mtu(500);
    if (local_mtu_ret){
        ESP_LOGE(ESP_NEDAP_TAG, "set local  MTU failed, error code = %x", local_mtu_ret);
    }

if you comment out line ret = esp_ble_gatts_app_register(PROFILE_A_APP_ID); - then erasing the flash works

erase function

Code: Select all

const esp_partition_t *partition = esp_partition_find_first(ESP_PARTITION_TYPE_DATA, ESP_PARTITION_SUBTYPE_ANY, "keys");
assert(partition != NULL);
esp_partition_erase_range(partition, 0, SPI_FLASH_SEC_SIZE)

I like this forum, I asked myself, - I answered myself

Helps stop advertising with a pause before the erase operation...

Code: Select all

void enabled_ble_adv(void)
{
    esp_ble_gap_start_advertising(&adv_params);
}
//-----------------------------------------------------------------------------------

void disabled_ble_adv(void)
{
    esp_ble_gap_stop_advertising();
    vTaskDelay(1 / portTICK_PERIOD_MS);
}
