@ -45,12 +45,16 @@ A new method `NimBLEServer::advertiseOnDisconnect(bool)` has been implemented to
`NimBLEServer::removeService` takes an additional parameter `bool deleteSvc` that if true will delete the service
and all characteristics / descriptors belonging to it and invalidating any pointers to them.
If false the service is only removed from visibility by clients. The pointers to the service and
it's characteristics / descriptors will remain valid and the service can be re-added in the future
using `NimBLEServer::addService`.
<br/>
New characteristic read/write callbacks added to NimBLECharacteristicCallbacks that receive a pointer to the connection
description of the client reading/writing.
This is useful when connected to multiple clients to discern which client is performing the operation.
