Exception: Bluetooth adapter not found (Pi Car-X)

Robotic kit for Raspberry Pi
1

I followed the instructions here:
https://docs.sunfounder.com/projects/ezblock3/en/latest/quick_guide_3.2/install_ezblock_os.html

The Pi boots and the hat speaker makes a sound, but I can’t connect via wifi or bluetooth. I tried laptop, tablet and phone. None worked.

EDIT: I can connect via SSH.

Please help me because this was a Christmas present and I need it to work.

this is the output if I run:

pi@picar:~ $ sudo ezblock-service

What version of Raspberry Pi are you using? You need a Raspberry Pi with Bluetooth.

Thank you for your reply. I am using Pi 2B.

I purchased this kit: https://www.amazon.co.uk/gp/product/B08FB6P88L/ref=ox_sc_act_title_1?smid=A337BOQBCQBMQG&psc=1

it specifically says " Raspberry Pi 4B 3B+ 3B 2B" in the description, but Pi 2B doesn’t have bluetooth.

I took my Pi 3B out of my media player and put it into the robot. It all seems to work ok now.

This is all very confusing and misleading. I would suggest you remove 2B from the description so that other people don’t make the same mistake.

Thanks.
