I also tried this with an ESP-WROOM-32 running the BLE_server.ino example file (to ensure it wasn't trying to connect with classic BT instead). Good news is it did show up...

Yes. I paired, unpaired and forgot, and repeated several times. The filter showed one or two malformed packets, but nothing beyond that.

Closing for now, as I do not have access to the device anymore. I'll reopen if/once I have tested it again.
