Re: Time Synchronization

This function has been synchronized to github, you only need to call `esp_mesh_get_tsf_time ()` to get the synchronized tsf time.

You can refer to: https://github.com/espressif/esp-mdf/bl ... ple.c#L220

Re: 关于MESH内部的通信协议

Hi Tony

ESP-MDF 中默认的以 P2P 的方式发包, 有重传的, 两个直接相连的结点之间传输是可靠的
向上传输,即子节点到根, 有流控,可以保证可靠性
向下传输,即根节点到子节点, 如果向端节点内存不足队列满了会丢包

Re: esp_mesh_set_parent 重新连接问题

1. 201 对应的错误码是 WIFI_REASON_NO_AP_FOUND, 你需要自行加上

Code: Select all

|| event.info.disconnected.reason == WIFI_REASON_NO_AP_FOUND
2. 由于手动组网的方案,组网的过程需要你自己跟据需要来添加, example 中并不包含所有的场景. 我们还是推荐你使用自组网的方案,如果自组网方案不能满足你的需要请提出? 自组网方案参见: https://github.com/espressif/esp-mdf

Re: Sending data bigger than 8kB with MWIFI Router Example

ESP-MESH does not support data stream transmission. When the data packet exceeds 8k, fragment transmission is required. Our OTA data packet is also more than 1MB, and the method of fragment transmission is also adopted.

Re: Reduce the connection time of Root node

You only need to modify the Mesh softAP association expiration time to 10000ms.

Re: ESP-MESH + ESP-NOW

1. ESP-MESH\ESP-NOW\Connecting Router can be run simultaneously on one ESP32 2. At present, ESP-NOW only supports binding of 20 devices at the time of sending, and receiving data is not limited. 3. The power consumption of ESP-NOW can be found at: https://github.com/espressif/esp-mdf/blob/master/exa...
