Sunfounder keyboard

HI, I bought an RPI 3 system from you several years ago that came as a complete computer with small display and keyboard. I am trying to use the keyboard in another function but I can not get any system to recognize it as Bluetooth. Is it supposed to be Bluetooth and if not what do I have to do to get to work? The chat bot suggested it may not be discoverable. How would I put it into discoverable mode? TIA.

Please a picture of the product.
Also please specify the running error example with pictures or videos.

There is no error message. It just looks like it is going to pair but does nothing.

Thanks

Hi
Does this help?

YES! You gave me the ‘secret’ key combination to enable discovery.

Thanks for your help.

Brilliant. Glad to be able to help
