Re: WiFi meshed network - how to join strongest AP in STA mode?

Hi,
You are using ESP32 as a standard wifi station rather than mesh station, and the mesh network is not built with esp32, right?
It would be better if you could provide some logs.

Re: Using ESP32 with existing Mesh networks that use OLSR?

Hi chibill,
ESP32 doesn't support Ad-Hoc mode actually.
Our esp wifi mesh protocol is different from the 802.11 wifi mesh. So I'm afraid that there's no relationship between OSLR and esp wifi mesh.

Re: problem with simple esp_mesh_send command

Is this the line 398 in mesh_main.c ?

Code: Select all

broker_addr.ip4 = ipaddr_addr("192.168.2.2");
The type of broker_addr.ip4.addr is u32_t, but broker_addr.ip4 is not.

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.
