I gave up on bluetooth. It was exciting my coil too much. Likely because it has no shielding yet, A few gotchas I noted on the way: The bluetooth stack on ESP32 is huge. It took up half my memory and left no room for the code. I tried another ESP variant but it only supported Bluetooth LE (low energy). The software stack and code for LE I thought was overly complicated compared to the original bluetooth. What I really wanted was bluetooth low latency, but the ESP32 doesn't support that yet. In the end I used ESP-NOW which works really well.

I realise a lot of this is irrelevant to the OP, but watch out for those bluetooth versions when going down that road. Low latency is the only option. Bluetooth has a time lag. Even the newer LE version.
