在gattc_profile_event_handler的ESP_GATTC_CONNECT_EVT中将代码改写成： case ESP_GATTC_CONNECT_EVT: ESP_LOGI(GATTC_TAG, "ESP_GATTC_CONNECT_EVT: conn_id=%d, gatt_if = %d", spp_conn_id, gattc_if); ESP_LOGI(GATTC_TAG, "REMOTE BDA:"); esp_log_buffer_hex(GATTC_TAG, gl_profile_tab[PROFILE_APP_ID].remote_bda, sizeof(es...

for(i=0; i<ESP_BLE_PWR_TYPE_DEFAULT; i++){ ret = esp_ble_tx_power_set(i,ESP_PWR_LVL_P7); if (ret) { ESP_LOGE(GATTC_TAG, "%s set ble tx power failed: %s\n", __func__, esp_err_to_name(ret)); return; }else{ ESP_LOGE(GATTC_TAG, "%s set ble tx power success\n", __func__); } } 程序中加入以上代码后，测试距离，没有什么变化啊!!

目前用ESP32-WROOM-32做一个产品，ESP32做BLE的client去连接另一个设备(这个设备与手机通讯时的距离大于30米)，发现2者之间的距离只有7~8米，不能满足需求，请问有什么办法可以增加这个距离呢？

ESP32如何触发软件复位？

By submitting an error to espressif officially, I received the following reply: I found out that this was because the iPhone did not send a deauth packet when the wifi was turned off, causing 32 unable to detect that the phone was disconnected. When ESP32 is used as Ap, if the STA does not receive d...

通过向乐鑫提交BUG，得到如下反馈：
经测试发现出现这种情况是因为iphone手机在关掉wifi的时候没有发送deauth包，导致32检测不到手机断开。而ESP32作为Ap的时候，如果超过5min没有收到STA的数据，则会主动踢出STA。

Is anybody know why?

When using ESP32 as a hotspot, if you connect the module with an Android phone or a computer, the module can detect that the Android phone/computer is disconnected when disconnected. But with the Apple phone connection module, when disconnected, the module seems to often fail to detect that the Appl...

用ESP32做热点时，如果用安卓手机或者电脑连接模块，在断开连接时，模块能检测到安卓手机/电脑断开了。但是用苹果手机连接模块，在断开时，模块好像经常检测不到苹果手机断开了。是通过SYSTEM_EVENT_AP_STADISCONNECTED事件打印调试信息来观察的。
这样导致的问题是，当设置只运行1个STA连接模块时，即使是苹果手机已经关闭了WIFI，其他手机也无法连接模块。
有人遇到过跟我一样的问题吗？
