Hi @MX ,
SES ESL integration is a per-AP feature. If you use a template, ESL needs to be enabled on a template level, and a V:Cloud URL needs to be set (assuming that you are using the direct connection to V:Cloud). Then, ESL functionality must be activated on individual APs within each child network.

There is no impact on BLE functionality for APs that don't have ESL enabled unless you explicitly turn off BLE on the template level.
