TL;DR

This version fixed the MTU request when the connection was made with automaticallyRequestHighestValueLength flag:

centralManager.connect(
   peripheral,
   options = CentralManager.ConnectionOptions.Direct(
      automaticallyRequestHighestValueLength = true
   )
)

Also, a onSubscription callback was added to RemoteCharacteristic.subscribe() method. Read more in the documentation: https://nordicsemiconductor.github.io/Kotlin-BLE-Library/html/client-core/no.nordicsemi.kotlin.ble.client/-remote-characteristic/subscribe.html
