<![CDATA[ATOM 2D/1D Barcode Scanner - Lock parameters changes via QRcode]]>Hello,
I would like to block changes to parameters programmatically or set them via Serial API on ATOM 2D/1D Barcode Scanner - https://m5stack-store.myshopify.com/products/atom-2d-1d-barcode-scanner-kit?_pos=1&_sid=fa7d06b74&_ss=r.

Anyone knows if this is possible?
Currently changes to qr scanner configurations can be done via QRcodes - https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/atombase/AtomicQR/AtomicQR_Reader_EN.pdf - and I would like to stop that, when we deploy the unit.

Regards,
Mateusz

I scanned the Factory Reset and now cannot
get the scanner to work with my code. A factory-fresh ATOM does still work.

But I too think there should be a way to disable QR codes. In particular, since the ATOM is
receiving the scanned QR - it should be up to the application to do what it wants with the scanned
value.

My sample arduino code is at: M5 Atom Testing

UPDATE It seems there is a prohibit scanning of configuration modes, as follows (and defined in their document Commands

uint8_t prohibit_scanning_config_mode_cmd[]  = {0x07, 0xC6, 0x04, 0x08, 0x00, 0xEC, 0x00, 0xFE, 0x3B};

thanks,
