Native: tried calling BLE.startScan, but the BLE plugin is not installed.

The report concerns ionic serve --devapp with the Cordova BLE plugin on Android; start by tracing the DevApp reload path after the first successful run. Reproduce the restart sequence and use the logged plugin_not_installed warnings as the failure signal; done means the BLE plugin remains available after restarting DevApp.

Description:

I'm using Ionic cordova BLE plugin. When I run

ionic cordova run android

Everything is fine. However when I run

ionic serve --devapp

The first time it works. When I restart DevApp application. It tells me that the plugin is not installed although it's well installed and it works fine.

Steps to Reproduce:

Output:

[INFO] DevApp connection established from SM-G965F
