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.
Is there a solution that can indicate the discount for customers with a certain distance?
Yes, there is. For example, we can provide both ESL with LED light and with RED Color.
Can I use phone App instead of AP?
Yes, you can use phone App or other Bluetooth device (such as Raspberry pi) which support BLE4.0/5.0.
What’s the next after I bought the ESL system?
We provide API, demo and tools to create display template and implement to your own software/plaftorm.
