How do I get the Bluetooth MAC Address of the device connected to my ESP32?

Hey guys I trying to understand the ESP-BT commands to figure out how I can pull the Bluetooth Address of the device connected via Bluetooth to my ESP32.

My goal is to save it so that next time I power up I will go searching for the device instead of having to pair it everytime...

Thanks Richard

If you're a peripheral, then you'll receive the remote central's address in the connection event (_IRQ_CENTRAL_CONNECT).

But as a peripheral, you likely won't be able to reverse roles and connect to the other device -- most devices are typically one or the other. (unless you control both sides I guess?).

Thanks for the info, any suggestions how to go read that address???

commands related to that???

I'm not sure what you mean sorry... It's passed to the event in the data tuple.

If you use aioble (https://github.com/micropython/micropython-lib/tree/master/micropython/bluetooth/aioble) then you can access device.addr or device.addr_hex().
