Dear @Stan_Stephenson,
it seems that nobody has answered you earlier ? If yes, please apologise for that.
I don't know if you've solved on your own, but whether you're still waiting for an help, please have a look at the following link:
In the mentioned showcase, I've used an ESP32, which features both BLE and Classic BT comm's, to verify if an app, made with AI2, can connect both types of BT at the same time.
Probably is more than what you need, but by elaborating it you can achieve what you want.
I agree that the Nano ESP is a different thing, but most probably it is not so different with respect to the standard ESP, so you can get some aid from my original post where you can find the ESP32 code, the .aia and some notes.
Best wishes.
