I need to connect scanner in SPP Mode instead of HID mode so keyboard will not auto-hide/appear on device connect-disconnect
You do not need to use SPP mode in order to display the keyboard while the scanner is connected.
- Connect your scanner
- Go to Settings > Language & Input
- Select Default or Current Keyboard for Android 4.x and 5.x, respectively
- Turn
Hardware Physical Keyboard
to off (4.x) or Show input method
to on (5.x)
Now the virtual keyboard wont auto-hide/show on connect/disconnect
For the ESKT_UNABLEOPENDEVICE
and ESKT_NOTHINGTOLISTEN
you'll have to edit your question to provide the complete stacktrace
