I am trying to establish a network between my esp modules but no luck till now.
I need to connect all modules to each other and to my wifi modem to use ota.
To do so, I have to connect all modules to WiFi which results a limited range.
My question is: is there a way to establish a network between all modules in a subnet and choose one module to connect to that subnet AND modem to reroute ota traffic? I want to know if there is a way to interconnect modules to each other without need of modem and having an option to add a module as connector between internet and that subnet.
Something like this:
module ip range: 192.168.0.2 to 192.168.2.255 (subnet)
one optional module with ip 192.168.0.1 in subnet and 192.168.1.2 in modem enabling ota in all modules. (OPTIONAL FOR OTA)
Kind of crazy question. but is there any solution?
Sorry for my poor English.
Thanks.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

I found some libraries that build mesh but each has some limitations:
easyMesh: No OTA.
painlessMesh: No OTA.
ESP8266MQTTMesh: Needs a MQTT broker. Using an arduino as broker limits the number of working nodes.
Any suggestions?
I need something like this:
