[Feature Request] Ability to clean up memory

[schlaegerz]

In my situation I am only using ble to do setup, so after my device is set up I would like to be able to completely clean up the memory and move on. So it would be great if there was a method to clean up the singletons, or some way for me to delete.

I have found I can do most with client code, but the singleton objects are impossible to fix up without library changes.

Here is what I was thinking

void NimBLEDevice::cleanup() {
  if(NimBLEDevice::m_pServer == nullptr) {
      delete NimBLEDevice::m_pServer;
      NimBLEDevice::m_pServer = nullptr;
   }
  if(NimBLEDevice::m_bleAdvertising== nullptr) {
      delete NimBLEDevice::m_bleAdvertising;
      NimBLEDevice::m_bleAdvertising= nullptr;
   }
  if(NimBLEDevice::m_pScan== nullptr) {
      delete NimBLEDevice::m_pScan;
      NimBLEDevice::m_pScan= nullptr;
   }
   for(auto it = m_cList.cbegin(); it != m_cList.cend(); ++it)
   {
      deleteClient(*it);
   }
   // Whatever other clean up needs to be done.
  
}

That's a good idea, perhaps that code should just be added to NimBLEDevice::deinit() then you could make one call to completely stop all BLE functions. You can reinit after that if you need to as well.
