ble_mesh_model发布消息的问题
Posted: Mon Apr 14, 2025 2:34 am
大家好：
我是新手小白，请教一个BLE_MESH周期性发布的一个问题。以标准on_off_cli模型为例，我想让on_off_sever模型通过发布的消息实现周期性的开关，可以通过模型设置发布的周期和地址，但是有个问题发布的消息无法回调更新(on_off状态和tid）。标准模型没有ESP_BLE_MESH_MODEL_PUBLISH_UPDATE_EVT这个事件，只有自定义模型才有。那如果我想用标准模型来实现发布自动更新消息该怎么做？如果需要手动周期性更新消息，那设置周期发布有什么用？我直接手动周期发布就可以了。请各路大神赐教，谢谢！
