Thx 4 quick reply.

Before I am in this situation, I already paired TC20 with my company file and everything is thru with build-in scanner except ITF-14.

With same device, ITF-14 can go thru via a BT scanner to finish picking / receiving.

With same device, ITF-14 do can be decode and tested via DWDemo and other app, like ZELLO.

From my opinion,  it looks warehouse manager app directly controls the build-in scanner and ignored ITF-14.

BTW,  I do reboot the device to verify this and problem still there.
