4. Software/hardware Architecture
How many ESLs can be managed？
It is no limit. But it will affect the updating speed if there are too many labels to be managed, We suggest each KESLGateway/base station manage 1000 ESLs.
Can I make custom content display on the ESLs?
Yes, we will provide the development kit. The development kit includes the instruction&tools to create the content, source code of these tools, and API.
How to establish relationship between ESL and AP？
You don’t have to establish the relationship between ESL and AP. You just need to follow the instruction and implement the AP to your platform/software.
