I got a no-name thermal-print toy camera (named "Q5"), with no obvious tech specs to look for. Anybody got one and opened the case or reverse-engineered the app?
It has "wireless printing", where it shows a QR code pointing to https://www.pgyer.com/UNhf - with bloated YinTiBao apps for Android and iOS. It does not have WiFi, but appears as a #Bluetooth#BLE device named "BQ05".
