Does Scanner.TriggerType.HARD actually works?

I am working with several Android modles (ET1, MC67 and TC75). Tried the EMDK for scanning. It works but only if I tell scanner to start scanning.

I am capturing the key press of the scan button and do the read command to the scanner.

From documentation the Scanner.TriggetType.HARD is suppose to start the scanner automatically but it is not.


From one example it said as a comment

// The trigger type is set to HARD by default and HARD is not
// implemented in this release.

// So set to SOFT_ALWAYS


Does the use of ScannerType HARD works or not?
