I just discovered this project and I’m interested using it for my school project. So I’m creating a temperature monitoring system using DHT11 with master/slave. System has 2 slaves and a master. Master also has display (I bought it seperately) it’s a i2c LCD 240x240.
I’m interested with the project because I just realized that WiFi and Bluetooth can’t run at the same time with the normal ESP32(?). Because I need my slaves to send data to master with Bluetooth, and Master send data via WiFi to MQTT, and receive data with Bluetooth. I don’t know if there’s a solution for this problem.
So the hardware
Sorry about asking this but how is the procedure to make it work?
- To connect display to master and show data from 3 sources (2 slaves, and itself)
- To implement OpenMQTTGateway to my system
Thank you so much, please let me know if details needed. Please let me know if there’s better way to do it.
I also have the code without OpenMQTTGateway here in my github repo. I’m so confused right now, don’t know what to do next.
