BLE witn ConnectIQ 3.0. Device GPSMAP 66s / 66sr / 66st

Good day!

As I can see this device supports "Generic Bluetooth Low Energy Channel". But the table https://developer.garmin.com/connect-iq/compatible-devices/ shows it's only API level 3.0.

  SDK shows me the same.

All the Toybox.BluetoothLowEnergy is available from 3.1. I cant use Toybox.BluetoothLowEnergy.BleDelegate, longToUUid, stringToUUID and so on.

And the question: Is there a way to get BLE working on this device?
