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.
3 . Each ESL will receive information and send a feedback message 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.
