How to get ble-in data to payload

I was wondering how to get data from bluetooth central device. I'm using node-red-contrib-epi-bluetooth module and on Android Lightblue app. I get the subscriptions from raspberry to Lightblue, but sending is now the issue.
Basically this is the flow im using. I Attached screenshots from Lightblue.

Im trying to send 1 value to raspberry ble in but no success, could someone help me with this?
