RFD8500 and Cordova App


I am trying to create a cordova app to communicate with the RFD8500. I am using the plugin cordova-plugin-bluetooth-serial to try and create the serial communication between the app and the RFD8500. I can establish the connection between both, but I am not able to send/receive any data between the two. Has any body been sucessfull on using the RFD8500 with a cordova app? I've seen here (Neptune Software Community) somebody saying that the use of the plugin is possible, but some customization is required. Does anybody has a clue on what that customization could be?
