Audio output via bluetooth from Arduino UNO

Other Hardware Audio
1

Hello,

I am trying to set a device for blind people based on ultrasonic sensors. I would also want to be able to connect via Bluetooth to the device and receive alerts when encountering an obstacle like "There is an obstacle in front of you at 2 meters". What do you think the best approach would be here? I know that I need Bluetooth modules that supports audio like RN-52 but I could not find any tutorial for this as I must mention I'm new to this stuff. I suppose I also need an SD card reader to store those alerts, right?

Thanks.

Update:

I have bought an ESP32 module as I understood it would be capable of doing the job but I still can't find any documentation on how should I configure them. Any hint?

Thanks.
