How to Hardware Reset JDY-10 After Incorrect Baud Rate Command?

[zwitch]

Hi everyone,

I mistakenly sent the command AT+BAUD8 to my JDY-10 module, which is not a valid baud rate value. The module responded with OK, but after that, I can't communicate with it anymore. I've tried all common baud rates from 300 to 921600, but the module remains unresponsive.

Is there any way to perform a hardware reset on the JDY-10 module to restore it to factory settings? I’ve already tried grounding the EN/RESET pin, but no success so far. Any advice on how to bring it back to life would be much appreciated!

Thanks in advance!

Let me know if you'd like to adjust or add anything!

My guess would be to hold pin 1 (of the module - not board) low.

According to the datasheet posted in the thread below, BAUD8 is 230400 ?

JDY-10 != JDY-10M

This is from the datasheet in the thread I linked:

View attachment 147328

this is an instruction from another module, you don't think that they are all universal and fit each other... besides, I've already tried all the speeds...

The author of the thread, who posted that data, (a long time use on here) was providing info specifically on the JDY-10, which he also gave usage info for.

The problem is that once any one original module becomes well known and popular, look-alikes appear, sold as the same part but often with different chipsets and just programmed as an approximate copy of the original device, for the commonest functions.

Which is which is anybody's guess, unless the original manufacturer is factually known.
