Sertag Bluetooth Electronic Labels

Q: Can a single device (such as a smartphone or Raspberry Pi) update multiple Bluetooth ESL tags on a scheduled basis without using a base station?A: No. Currently, Bluetooth digital tags can only be updated through direct point-to-point communication with a smartphone. For scheduled or automated updates, a custom gateway/base station application must be developed to receive update tasks from a backend system and distribute them to the tags.

Q: Do the Bluetooth ESL tags support the Bluetooth SIG ESL standard (Service UUID 0x1857 / PAwR)?A: No. The tags use Sertag's proprietary Bluetooth Low Energy (BLE) communication protocol rather than the Bluetooth SIG ESL standard profile (Service UUID 0x1857 / PAwR).

Q1: Does the SDK of Bluetooth electronic shelf label accept price or text data fields for the tag to render, or do I need to generate and send a complete bitmap image? A1: The SDK is responsible only for transmitting image data to the tag. Image generation and rendering are not handled by the SDK. Therefore, users need to create the bitmap image on their own system and then use the SDK to transfer the generated image to the electronic label.
