Thanks Guillaumme. I will try bluetooth first then get into ESP32. Appreciate it.

They are basically the same, except HC-05 can be set as a master but it's useless in your case, both modules will work exactly the same.

I recommend using the voltage divider (or better, a level shifter) but of course it's only needed if your dev board is 5V, and only on the RX line of the bluetooth module.

I haven't used these modules since a long time so don't ask me about configuration etc, I don't remember and don't want to.. Now I'm addicted to ESP32

1. I want to pass PID parameters to my self-balancing robot (and maybe later do some directional stuff) and would like to know if anyone has developed a preference for one or the other Bluetooth modules.
2. Is it necessary to use voltage divider on the bluetooth module to prevent eventual damage?

Thanks.
