How to set BLE Gateway V4 "Work Mode" to "Simple" like older Wireless iBeacon Receiver?

How do I set the BLE Gateway V4 “Work Mode” to “Simple” like older Wireless iBeacon Receiver?

I have it set in JSON format, but the output is too long. I need it to be shorter and only contain the MAC address and RSSI like the older Wireless iBeacon Receiver.

Gateway V4 doesn’t support “Simple” mode. What’s your requirement about your application?
