Re: esp-now and number of nodes [WIFI-2126]

Well it would be much cleaner interface, where can i find sources for esp-now and how can i modify it?. In my case i have quite a few peers but those are configured and saved to nvs/flash. So there is no point of keeping such list dynamic /in memory.

Re: esp-now and number of nodes [WIFI-2126]

why not allow a Send with key as parameter instead of managing peer list. This way user of the API can decide how to manage peers. In my case i could use NVS to store all the peer info as it only need to send messages occasionally.

ESP mesh and time sync

hi, i want to have multiple nodes those need to be in sync with time. I plan to designate one as root node that will sync time with ntp or gps and rest of the nodes will sync time with root.

How can i do it and is esp mesh available in arduino or i have to work with c/c++

Thanks
Sajjad
