Scales Known to Work with BlueSnap M6A Wireless RS-232 iOS, Android & More

BlueSnap M6A Wireless Bluetooth BLE to RS232 dongle/adapter can work to wirelessly enable hundreds of RS232 scale models.

The following is a list of scales that have RS-232 serial port support. Scales have been reported as working with BlueSnap M6A Bluetooth wireless dongle using apps like SerialMagic Keys iOS, Android, MacOS, Windows 10. This means they also can work with 3rd party apps that implement the Serial Device Manager (SDM) libraries. This list is not exhaustive by any means, there are hundreds of models that work.

Using the BlueSnap M6A and SerialMagic,  iScanBrowser, Mobile Grid, you can collect and process data from a scale into any native, web, or hybrid app on iOS and Android.

For 3rd party apps looking for a light-weight method to interface with the RS-232 wireless dongle for scales and other devices, consider the SerialMagic SDK.

Note: also supports other scale devices that have built-in BLE e.g. like the Tru-Test S3 Bluetooth Scale Head: S3 iOS, S3 Android
Contact if you needs support on some scale device not listed.
