Add connectable property to BLE Scan result

[mrx23dot]

Is your feature request related to a problem?

Asking for near by BLE devices don't tell me if they are connectable or not:

AT+BLEINIT=1
AT+BLESCANPARAM=1,0,0,1480,1480
AT+BLESCAN=1,3

  +BLESCAN:"2a:47:c4:d5:63:e0",-78,1eff060001092022c46a7a8bda0a542bd5141db069a0ad42393763cf091bae,,1
  +BLESCAN:"34:64:f4:2b:4b:97",-63,13ff0600010f210a1acca4f60ae0534330303934,,1
  +BLESCAN:"52:83:e4:05:8f:d9",-98,0303f3fe,,1

based on discussion in comments here:
https://stackoverflow.com/questions/28467590/detecting-whether-a-ble-device-is-connectable-on-android

"connectable" status doesn't come from Advertisement Flags but from environment (ESP AT).

Describe the solution you'd like.

is connectable
+BLESCAN:"52:83:e4:05:9f:d9",-98,0303f3fe,,1,yes
+BLESCAN:"52:83:e4:05:9f:d9",-98,0303f3fe,,1,no

or in number

Describe alternatives you've considered.

only other way to test is trying to connect but that's VERY slow.

Additional context.

I have seen Advertisement Flag 0x1A being connectable an also nonconnectable in nRF android app.
So I'm sure connectability is not stored in Advertisement Flags.

[mrx23dot]

You can have a connectable device without any included advertised Flags.
