Will My Phone Work with Kanda Loader App?

Not all phones will support USB and minimum requirements are

• Andoid 7.0 and up
• Phone supports USB host mode
• You need an OTG (USB On the Go) cable
• Not supported on IOS

To check if your phone supports USB host, check on the box, in manual or on manufacturers website. Look for this logo


Alternatively you can download a test App from Google Play - search for USB Host Check

OTG Cable
An OTG cable (USB On The Go) provides a USB host that connects to Kanda USB dongle with its USB A connector. The other end connects to your phone. If you don't have an OTG cable (USB On The Go), we have them on the shop for common connector types - USB C type and USB Micro B.

Read and Erase Buttons

These are optional functions that give you more flexibility.

Read Button
This button reads and displays the file description from the programmer. This is useful if you have forgotten what is loaded in the programmer.

Erase Button
The Load button will load the programmer with the new file but if your new PRG file is smaller, then the extra code will be left in the programmer. It will never run or interfere with the operation but it will affect things like checksums if you use them. Erase will completely clear programmer before load.

Example Application

You produce 4 different versions of your product that require different firmware to set their features. Just create 4 Kanda Programmer files (.PRG), one for each version. Email them to your engineer, distributer or warehouse. They use their Android device to connect to handheld programmer, select the correct file and reload the programmer for that version. They connect programmer to the target, press the button and new product features are set.

Need to change firmware quickly? Just create new programmer file, email it to phone and reload programmer, its as simple as that.
