// If we are bonded we may want to enable Service Changed characteristic indications.
// Note: This feature will be introduced in the SDK 8.0 as this is the proper way to refresh attribute list on the phone.
// Note: Sending SC indication on services change was introduced in the SDK 8.0.
// Before, the cache had to be clear manually. This Android lib supports both implementations.
// Note: On iOS refreshing services is not available in the API. An app must have Service Change characteristic
// if it intends ever to change its services. In that case on non-bonded devices services will never be cached,
// and on bonded a change is indicated using Service Changed indication. Ergo - Legacy DFU will
// not work by default on iOS with buttonless update on SDKs < 8 on bonded devices. The bootloader must be modified to
// always send the indication when connected.
// This has been fixed on Android 6 (?). Now the Android enables Service Changed indications automatically during bonding.
