Eview protocol updated: for Eview EV-07B devices parameter timestamp.key is added for all messages that are registered from 0x01 Data Command Key's.
timestamp.key is a synthetic parameter that is calculated based on the timestamp reported by device, packet sequence number and sequential number of the Key information in the 0x01 Data Command packet, that prevents merging of different messages with the same timestamp in the device's storage.
