JBL Pulse 3

Hi,
Not sure if I post this in the right place. I'm using the ESP32 to test audio through bluetooth.
I'm trying to find out if the JBL Pulse 3 or JBL Charge 3 devices are using Bluetooth Low Energy. I don't have any of these devices with me and I couldn't find any proof about this after 5-6 hours worth of searching around.
It looks to me like they are using BLE but I might be wrong. The [JBL Pulse 3 spec][1] says that the Connect App is supported and the Bluetooth version is 4.2 (BLE was added in 4.0). If we look at the [JBL Charge 2][2], the spec doesn't say anything about the app (not suppored) and the Bluetooth version is 3.0. To me this is an argument because I think that there's no way to send custom data (the pulse 3 uses LEDs) using classic bluetooth. In the spec they only specify support for: A2DP V1.3, AVRCP V1.6, HFP V1.6, HSP V1.2 but I think they're also using GATT, it's not specified because they don't want to support it but I don't see how they're able to use the app without GATT being added. None of the above profiles can't be used to send custom data (as far as I know).
