I'm busy to build several nodeMCU arduino ESP-12 to read temperatur, pressure and humidity bij different sensors connected to the ESP-12.
This is running and working fine.
I'm able to present this values with a webserver on the ESP-12 to look at ip-adress and port at an browser page.
What I like to create:
My Rapberry pi to read from the severall nodeMCU ESP-E12 modules (maximum 10) the different data and write this data into a file at the Raspberry
The Raspberry is having a fixed ip-adress. The ESP-12's have DHCP created ip adresses and are not known at the forhand.
How to create/ setup a webserver/client connection between Raspberry and the ESP-12's?
And read the data from all the ESP-12's?
I like to write the code at the Raspberry in Python. The code at the ESP-12's have to be in C.
Can somebody help to give or point to some examples to create this connection?
