how to use?

[enjoydiy]

frida -U -l ./blemon/frida/blemon.js com.tjd.tjdxxx

But not work.

Same. I also can't figure out how to make use of this. Nothing gets printed.

Any hints would be apericiated!

frida -U -l ./frida/blemon.js Gadget worked just fine for me (used frida-gadget on an Android phone running Nougat).

Note: no output will be visible until actual BLE traffic is going on.

Can confirm for me

frida -U -l ./frida/blemon.js -f com.package.name worked!
