Re: ESP MESH limitaiton of nodes around root node

Have you ever came across scenario like node N1 is connected to soft-AP1 and after switching connecting to soft-AP2. Meanwhile still soft-AP1 shows node N1 entry in its station list. In this case esp_wifi_internal_tx API goes fail between N1 and AP1. Yes, If soft-AP1 didn't receive the disassociati...

Re: ESP MESH limitaiton of nodes around root node

Hi Ankit, We have done some tests on 100 and 200 nodes in close proximity. The default configuration of network such as assoc_expire may not be appropriate, users should set it themselves. The throught can be affected by the environment. The network could become stable. The healing time is affected ...

Re: MESH Broadcast Message

I have some tests on broadcast message, and the device could continues to receive messages after it was re-connected.
Would you please provide some logs here? I'm afraid I didn't get your point.

By the way, MESH_DATA_GROUP is not needed.

Either is OK.
MDF APIs are easier to use and IDF APIs are more flexible.

If the packet is to the root, set this parameter 'to' to NULL.
