STBLEToolbox not discovering devices

[NicRoberts]

I have a HC-06 module being run via USART from a STM32F411RE NUCLEO board.

When I run STBLEToolbox (or LightBlue) the module doesn't appear in the scan list (all filters are off)

Yet when I open my Bluetooth settings on my phone the module shows up & I can pair with it. The module still doesnt show in the app even when paired though but I can use a serial Bluetooth app to connect to it.

What am I missing here?

Isn't the HC-06 Bluetooth Classic only ?

Aahh right makes sense. I'm guessing the protocols are significantly different enough that a BLE app will ignore classic devices?
