若网络内不存在根节点,ESP-MESH内的所有设备都会广播“实时信号强度RSSI” 信号。每个节点的网络信息,包括信号强度,都会传输在整个ESP-MESH网络内,ESP-MESH网络内的设备会根据这些信息选择信号强度最高的节点作为根节点。 POR,所有ESP-MESH设备被分别扫描。每个都会设备比较其接受到的其他设备相对于路由器的信号强度以及...
如需低成本或低功耗 Mesh,可考虑ESP32-C(Thread/Zigbee 协议),但需搭配外部射频芯片(如 802.15.4)。 ?计划使用手机进行初次配网操作,是否esp32只需node角色,配网后可以与jdy自动组网通信。2.ESP32模块在使用了蓝牙MESH、mqtt通过wifi连接后,还可以扫描周围蓝牙广播包吗?
There is an ESP32 library for MQTT protocol which is called “ PubSubClient”. That can be used to connect to MQTT brokers and publish/subscribe to topics in your IoT applications. And we’ll be doing a handful of projects to practice using the MQTT protocol in different applications in ...

Hi @chegewara, Thanks for replying. I will try the way you suggested, hopefully it should work. I need bi-directional communication, like if any node in mesh sets (on or off mode) then it should be able to update on cloud through mqtt. is this possible to get all node status data ...
mesh begin can now run without WiFi disconnect (speeds up boot time, important for PIR sensor sleeping nodes) new function for sending messages with specific message ID (future support for multi mqtt gataway setup) message roundtrip reduced as much as possible to get more reponsive real-time ...
