DiscoverCharacteristics method returns after discovering all characteristic declarations, characteristic values and descriptor are read in "background". "Read Not Permitted" needs to be fixed. Feel free to send a patch for it. The characteristic value is required due the GetProperties method of the characteristic "object". At the moment, the characteristics storage is not being used properly. For example, Proximity could read the handle from the storage if available.
