ESP-BLE-MESH with WiFi CoEx

[mpoonawala]

Hello there,
I am working on a project and I need your expertise to guide me in the right direction.

Details:
I have 30 esp32 custom boards with an LM35 temperature sensor, I can read the data correctly.
The wifi provisioning is also done, I can connect to wifi and my MQTT server.

The Photo attached has two diagrams
Legends:
1)Yellow Block: WiFi Router
2) Dark green Circle: Node
3) Light green Circle: Distant Node, wifi No wifi signal range.
4) Red line: WiFi connection of the nodes with the Router.
5) Blue Line: Shows the BLE mesh network.

The diagram on the TOP is done.

Guidance:
Need Assistance to do the bottom diagram.

Example: A distant node will read the temperature data, send that data to the node connected in the mesh that has a wifi connection, and that node will send the data to the MQTT server.
