Help with communication

burddb10

I am making an IoT Project involving an AI Thinker ESP32CAM and an ESP32-WROOM-DA (Module), the objective is waste classification using the cam and it sends the classification to the ESP32 Module which controls the servomotors for the sorting process. This is an automatic waste segregation, and I already have a trained model utilizing Edge Impulse platform. I already have a circuit, but my problem is that I don't know how make a two-way communication, I have tried it but failed many times already. Any idea what to do? Thanks!

Hi! I have done several sensor based on rp2020. I included a MQTT library and connected to the IoT Open platform. Then it is easy ta implement two way communication.

There are great mqtt libs for e.g. Micro Python or C.
