ATOM-ECHO

Purchased recently three M5Atom Echo units on amazon.com and the seller was advertised as the M5stack store.

Spent quite some time to get the microphone working with no positive result. After intensive research tried the repeater example from this site and programmed all three units with Arduino IDE. The button does nothing and there is no feedback response from the microphone.

Opened the case and noticed that the board version is ""v1.1 Echo". The board seems to be slightly different from V1.0. Every other test regarding the LED and speaker mode seem to work OK! All three have the same problem.

Is there something else that I'm missing with these new units? Could these be fake units?

Thanks

Hi @molly200,

How did you compile Repeater.ino sample? There is a i2s.h include, but it is not in this repository.

Well, I forgot to select the m4atom board in Arduino IDE :-D

Now I can compile the sample code, but I'v got no sound output.

Mine is not working either. At first, I couldn’t make Home Assistant Assist work. So I decided to try the repeater example, and the mic is not working. It is just the mic, as the speaker test is working fine.

Can you try this exemple and see if the mic is working : https://github.com/m5stack/M5Atom/tree/master/examples/Echo/RecordPlay ?

I tested that RecordPlay and it worked fine. I can record my voice and hear it (very quietly though)

Hi @alfem by any chance did you figure out ways to volume up the audio output?

I'm on a v1.1 and I can't get the mic working, even with alternate code that only prints to serial. Help?

Me too, I cannot find any code whatsoever that results in the mic actually recording anything. Serial output is all zeroes.

I've wasted so much time.

This repo hasn't been maintained in years - barely anything even compiles here. I can't find anyone who has bought an M5Atom Echo recently and has got it to work using example code.

I had the same Problem. I tried this Example (Arduino IDE Version 2.3.3, Board Version 3.1.1) and it was not working. When I tried with following Example https://github.com/m5stack/M5Atom/blob/master/examples/Echo/RecordPlay/RecordPlay.ino (Arduino IDE Version 2.3.2, esp32 Board Version 2.0.11) it worked.
