Re: Sending sensor data to other node using ESP-MESH

It might be a little easier if you use ESP-MDF. If you want to send data from one node to another use IDF only. First, you need to know how to use esp_mesh_send() https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/network/esp_mesh.html#_CPPv413esp_mesh_sendPK11mesh_addr_tPK11mesh_da...

Re: ESP-MESH timeouts

I think it is not not possible to reduce the healing time under 5 sec. That's the design. The assoc_expire can not be less than 10 sec beacuse the network may be instable. `esp_mesh_send` returns after disconnection. By the way, When a parent node is powered off, the child node will: 1. detect the d...

Re: ESP-MESH timeouts

Yes, it's esp_mesh_set_ap_assoc_expire. For non-root mesh nodes, beacon timeout = inactive timer = assoc expire. The parent's beacon interval will not impact the child's beacon timeout. Beacons are boardcast frames, they have a big impact on the environment. So it is expected to reduce the frequency...

Re: ESP-MESH timeouts

Hi cvar12,
1. There's no ack timeout in esp_mesh_send now.
2. `esp_mesh_set_assoc_expire` could change the time of `beacon timout` and `inactive timer` on non-root mesh nodes.
3. Not available now.

Re: Internet Access

Hi ChapsF,
Non-root nodes do not have ip address and do not support TCP and UDP.
I think that's why NtpClient doesn't work.

Re: LR mode in mesh

I think LR mode can be used in ESP-MESH.

The rssi configuration depends on whether the nodes can connect or communicate smoothly. If you use LR, the rsssi should be able to set lower.

Re: 请问哪里可以修改WIFI线程的stack size?

应用无法随意修改wifi task的大小。

“W (288148) wifi: m f probe rsp l=196”
这个问题与wifi task的大小没有关系,是设备作为 softAP 需要回复 `probe rsp` 过多达到了限制没有及时发送出去。你可以检查一下周围是否有很多设备在执行扫描操作或其他干扰。尝试更换信道或将AP设置为隐藏模式等。

Re: Merge mesh networks into one.

Documentation says: "The networks of the multiple root nodes will be combined into a single network with a single root node. However, root node conflicts where two or more root nodes have the same router SSID but different router BSSID are not handled." This mechanism only works when multiple root ...

Re: Using Wi-Fi with ESP-MDF

This behavior has some changes during adding channel switch functions.
On the current IDF version, The device will not tell others it's root before it connected with router. So the other nodes will not connect to the root which is connecting to router.
