STBLEToolbox not discovering devices

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 ?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

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