Hi there Stackoverflow community!

I’m going to start a BLE application with the ESP32 microcontroller. I will need to send 3 different types of data back and forth between a mobile app and the ESP32.

My question isL what is the best BLE architecture to do this? Should I create 2 services RX/TX and just send the data with an attached byte to know the type? Or should I create 3 services for each type of data?

I feel the RX/TX is easier but I would like the advice of more knowledgeable people. Thanks a lot in advance
