esp 使用几次后蓝牙搜索不到问题？

[yunji_2.4G]

我公司使用esp32作为蓝牙设备，现在发现的问题如下：
1、生产完毕后蓝牙搜索不到。这种情况没有进行过其他软件方面的检测，硬件方面检测和处理后仍然搜不到；
2、用户使用几次后，蓝牙搜索不到。
2.1 退回公司后，发现Android搜索不到，苹果lightblue可以搜索到连接不了。
2.2 重新烧写ble_spp_server测试：Android搜索不到，苹果lightblue可以搜索到连接不了。
2.3 重新烧写gatt_server_service_table测试：Android搜索不到，苹果lightblue可以搜索到连接不了。
2.4 重新烧写ble_spp_client测试：esp32可以搜索到其他外围设备
2.5 WiFi AP可以使用，蓝牙打印信息正常，为报错。

请问，这是什么原因？如何避免？现在大概1%出现几率

Hi,
1. 请提供你们使用的 IDF 版本信息和 gatt_server_service_table example 的测试 log 信息.
2. 在 gatt_server_service_table example 中将 adv_params 参数中 adv_type 设置为 ADV_TYPE_NONCONN_IND, 重新烧录后测试 Android 手机是否能搜索到设备广播
static esp_ble_adv_params_t adv_params = {
.adv_int_min = 0x20,
.adv_int_max = 0x40,
.adv_type = ADV_TYPE_NONCONN_IND,
.own_addr_type = BLE_ADDR_TYPE_PUBLIC,
.channel_map = ADV_CHNL_ALL,
.adv_filter_policy = ADV_FILTER_ALLOW_SCAN_ANY_CON_ANY,
};

感谢您的回复，以下是我测试结果和打印信息，

static esp_ble_adv_params_t adv_params = {
.adv_int_min = 0x20,
.adv_int_max = 0x40,
.adv_type = ADV_TYPE_IND,
.own_addr_type = BLE_ADDR_TYPE_PUBLIC,
.channel_map = ADV_CHNL_ALL,
.adv_filter_policy = ADV_FILTER_ALLOW_SCAN_ANY_CON_ANY,
};
这种情况搜索不到蓝牙，打印信息如下：

这种情况，可以搜索到，但是无法连接，我们无法使用。打印信息如下：
