Projects General Guidance

As mentioned in Headline

I am facing a small issue with recently purchased DF player modules
The unit I am currently working with is from year 2021 or 2022

The loop play for an audio file is working great as per it's command
But with recent models and with hardware and software connections
none of the purchased items from AMAZON is able to play loop . . ...

I am purchasing , testing and returning :sob:

Please help me with the issue

Do they have some modern type code or something or product with loop facility is not available now a days in forth coming models

Please suggest me form the list below if may be I am not selecting the right part

Thanks !!!!!!!!!!

Which DF modules? They are clearly not 100% compatible. Look at the prices. You surely get different stuff comparing 201 and 2 - 3 000 USD stuff.
Telling the different prices doesn't help us. Please dig up the datasheets and look for applications etc..

OK where would I find the compatible datasheet with that particular available module ??

Previously I purchased so many times but never had to face such condition some 3 to 4 years ago !!
