One of the most important message properties is Message-ID. Message-ID is automatically assigned when you create a MesiboMessage object. However, you can change it if requires. You should use a unique Message-ID for sending each message so that you can identify the message when the message status is received.

Message-ID is a 32-bit unique id. It will be converted into a 64-bit globally unique ID by the system. The ID which you have originally passed will be preserved in the lower 32-bit of the globally unique ID.

For example, if you send a message with id 0x12345678, it will be converted into global id 0xXXXXXXXX12345678 when delivering your message to the receiver. If you use zero Message-ID, the message will be delivered only if the recipient is online, it will be discarded otherwise.

You should use zero message-ID only for cases where storage is not required, for example, presence information like typing indicators, online status, etc.

You can set Message-ID by assignment.

message.mid = 0x12345;
message-id, expiry, ttl, title, subtitle, data, remote peer
