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, so it’s better to put 200-400 under one KGateway01C.
How long to receive the latest data for ESLs？
ESLs search for a new order every 20s. And they will carry on the new
order. Thanks to the clock circuit, the ESLs can display required information in time.
How to establish relationship between ESL and AP？
ESL can search for the AP with the strongest single and connect with it. And it will find a new one while the current single disappearing.
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.
