Working without a signal
Keep scanning in a dead spot. What you validate is kept on the phone and posted when the signal returns, never twice.
What works without a signal
When the phone loses its connection, a yellow bar says No signal and the app keeps working:
- The home screen opens with the lists as the phone saw them last.
- Scanning items and bins works from the items the phone keeps.
- Receive without order, Goods issue, Direct transfer, Pack and counting work as usual.
- Validate keeps the document on the phone: No signal: it is kept on this phone and posts when the signal returns.
Opening a purchase order, transfer request or sales order, and stock figures on the item card, need the signal.
The phone keeps the items of your company after you open the Barcodes app once with a signal. It refreshes them when you open the home screen with a signal and the kept copy is more than half an hour old.
When the signal returns
What was kept is sent by itself, oldest first. The card at the top of the home screen shows what is waiting; Send now sends it at once.
Each kept document carries its own key, and Voltix posts a key only once. Even if the phone sends the same document twice (for example when the answer got lost on the way back), it is posted once.
When something is refused
If Voltix refuses a kept document (for example the stock ran out meanwhile, or a type was switched off), it stays on the home screen in red with the reason:
- fix the cause and press the try again arrow, or
- press the delete icon to throw it away. It was never posted, so nothing is undone.
