Question - How to change the UART baud rate of the JQ6500 device?

[mst0mst]

Greetings NikolaiRadke,

This is more a question than an issue, sorry if there is another way to communicate between GitHub users...

Do you know the way to permanently change the JQ6500 MP3 player module baud rate?

I am in the need to interface it with a very ancient system, its maximum UART operation can reach 4800 bps instead the JQ6500 default.

I am aware of the man in the middle solution, use a microcontroller, but this solution appears to be a waste of resources for only a serial port input, followed by a slower serial port output.

Thanks in advance!

I know the question is very old, but still worth getting an answer, I think.

Have you ever just tried it with 4800 Baud?

AFAICS the JQ6500 does not have a fixed or default baud rate, but uses the 0x7b prefix (01111110 binary) to auto-detect the sender's baud rate for every command that arrives. So, unless 4800 Baud is too slow for the chip's detection routine it should just work. So, try it out and let us know how it went.

Oh! Thanks for answering! I've overseen this question. Sorry.
