M5 Atom QR-Code Scanner Factor Reset Broke Device

konacurrents

I've been using the QR-Code scanner successfully, and all my code works in the M5 Atom. It's
amazing that that small device can run all the same software as my M5 (minus the display). I have
MQTT and BLE working nicely.

Anyway, I have a version that interacts with the QR-Code scanner. My version is based on the ATOMQR_UART_CMD.cpp code. I was trying to get the device to "mute" on startup, and actually had it working for a short time (until the factor reset I'll describe next).

Here is my issue:

I scanned the "Factory Reset" QR code from AtomicQR_Reader_EN.pdf

Now the device will not work. This means no lights and no scanning.

The M5 Atom still works (MQTT and BLE) but it doesn't QR Scan anymore.

QUESTION: is there a way to get the device back working through the arduino download?

Help.
thanks.

Hi Scott,

I ran into the same problem. Did you find a solution?

@Scotty42 I haven't been using the QR scanner as much especially as I cannot get the startup sound to go away (and it freaks my dogs). But the scanner works.

What issues are you having?

@konacurrents See here: https://community.m5stack.com/post/28583 . Maybe the suggested solution would work for you as well ? I couldn't test it but will do so in the coming days and report back.

@Scotty42 I have used that barcode scanner to configure the QR scanner so will have to re-visit that approach. I have got the sound to go away but forgot how to do that. I have tried code to do that. Unfortunately some of these devices have a pre-state, like when powered up, which makes a sound before I can turn sound off. (Same with H-Driver and Atom Socket I just posted)

There is a mode to not accept those barcodes (so an end user cannot change some setting your code didn't want set).

Right now I use MQTT/BLE to set what it would scan - and then play that back from a button click. Basically store and re-play later - just like the QR code scanner achieves.

For my system, the QR code will invoke messages in my network - to turn on the lights, or feed the dog. I call this a Semantic Marker(R).

cheers,
thanks,

@konacurrents Note, I have a similar startup issue with the Atom Socket and H-Driver.

Anyone know how to stop it starting before I get a change to stop it?
