Re: kaluga devkit

Hi chegewara, First of all, thanks for your understanding. 1. the issue with RST button: Because the strapping 45 and 46 are used in the camera and audio board, these two would interfere the RST function. This would be updated in V1.3 later. 2. The LCD screen in the kit is not a touch screen, we wan...

Re: Is ESP32 Mesh a viable solution?

Hi Sam,

We would suggest to split the network into smaller one, like 200 devices for a network. The network can be separated with different MESH ID.

How is the distance would be between devices you set up? And is there low-power required?

Re: ESP IDF Version Support with MDF

Hello,

Yes there is breaking changes from IDF3.X to IDF4.X, so currently we still working on IDF3.X, the one we believe stable.

We are working on this and soon we will update the release v1.0 with IDF3.3 support, then we will update the master branch with IDF4.X mid-April(current plan).

Re: Setting up esp-mdf

Hello,

Sorry for the late reply. It's same way as setting up the tool chain for IDF, just please use the toolcain for IDF 3.X, not the one for IDF4.X.

Re: ESPNow vs ESP Mesh vs MESPNow

Hi chaitz, Actually there is no much connection between these two protocols, only because we think ESP-NOW https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/network/esp_now.html can perfectly meet our low power requirements, then we add it into our MDF. For low power devices, using...

Re: How to test ESP Mesh Network

Hi hetal, Yes in our algorithm we will tradeoff between the deep of layer and RSSI between nodes, for example you have a root A and a 2nd layer node B, another node C has both good RSSI with these two, then C will connect to A as a priority. But when C has much better RSSI with B than with A, then i...

Re: ESP MESH 可以将所有的节点都连接至路由上吗

您好,

数据的延时与设备所处层级、网络环境有关系,我们实验室测试一层的延时大约在 10~30 ms,和普通 Wi-Fi 设备的延时差别并不是很大。

如果需要连接路由,建议使用 有路由 版本的组网方案。固定根节点的方案,如果根节点瘫痪,网络是会出现问题,因此建议可以采用多个根节点进行备份。

Re: mesh 的root节点能否通过 4G拨号实现联网?

Hi shb3618,

抱歉回复晚了。目前没有专门针对该场景的应用,可参考 MDF 中 no-router demo,该 demo 根节点直接通过串口和电脑通讯,可修改成将数据通过 4G 模块进行传输。

Re: 关于MESH内部的通信协议

Hi Tony,

Mesh 网络内部,是基于数据链路层的自定义协议,即我们核心之一。有 ack 机制,但是没有 超时/重传 机制,如有需求自行可以在应用层添加。

Re: mesh 关于内部节点之间的通信疑问

Hello, 1、节点之间能通过socket api直接通信吗? 可以的,参见 https://github.com/espressif/esp-mdf/tree/master/examples/function_demo/mwifi/router。 2、若节点有LAN口,通过socket 和 LAN 上的其它设备通信是否受限制? 不受限。 3、mesh 和 通常的wifi 是共存的吗? 就是加入mesh网络的节点,这时还能作为普通wifi设备连接或作为ap被其它wifi设备连接吗? 作为 mesh 节点后,Wi-Fi 相关功能会冲突,不能作为 AP 被其他 Wi-Fi 设备连接。但是可以启用...
