How does the ESL system work
1 . Input information for production into the database serve,
either by manual input or scanner device.
2 . The server will give command and information to various Access
Point(AP), set in the market or warehouse, each AP controls a group
of ESLs via Bluetooth.

to AP and eventually to the serve. If the feedback is correct, ESL
will finally update its new item information, if failed, the server
will alarm and prompt to update again.
