code39 barcode issues

Issue description:

we get incidents on a regular basis from stores that seems the device scanners sometime decode the back room locations incorrectly. It is usually a character that is misinterpreted as the examples below sent by stores indicate. We haven’t been able to reproduce this in our lab environment. Could you please run it by your internal teams to see if they have any ideas or have seen reports from other customers? Looks in 2015 the scanners on PDA exhibited similar behaviors but it seems no one remembers how it was fixed. This is an urgent matter and is causing issues for backstocking in stores so any help is greatly appreciated. Thanks. 

Scanned “L01A004E29”

Read as: “L01A004F29”

Misread “E” as “F”

Scanned “01A10J28”

Read as  “01E10J28”

Misread “A” as “E”

Based on our old emails we found that we were advised to set the below settings for PDA's, I'm trying to set same set of attributes(redundancy as all thrice, bidirectional as true flag) for TC51 and TC56.

My Code to support the above window:

ScannerConfig config = scanner.getConfig();

config.decoderParams.code39.length1 = 8;

config.decoderParams.code39.length2 = 24;

config.decoderParams.code39.redundancy = true;

config.readerParams.readerSpecific.laserSpecific.linearSecurityLevel = ScannerConfig.LinearSecurityLevel.ALL_THRICE;

Please advise about my changes  and let me know if there are any performance issues with ALL_THRICE setting as the document says  - Three times read redundancy for all bar codes.

Let me know if you need any other information.
