Yes I've seen and tried this tutorial many times. But the problem is that this tutorial interfaces with a phone. It's a bluetooth serial bus between the Android and the ESP32. I am looking for a BT serial bus between the HC-05 module and ESP32.
I would plug in both boards to my computer and look for the ESP32 in the list of BT devices on my computer. My computer would connect but the connection was very unstable which is why it was rare to see any messages in the HC-05 SM. But it did happen.
Earlier I was told to put the ESP32 board into master/slave mode but I am unable to do that since AT commands are not being responsive. Does anyone have experience configuring the ESP32 as a slave board? or any other advice on creating a more secure BT connection between the two boards?
