BNSendGameData to self

[dsmania]

I have an scenario where I want to communicate 2 WoW accounts under the same Battle.net account, on different servers and factions.

I've successfully done it using BNSendGameData with different Battle.net accounts, but when I use it with the self presence ID I get an error message:

"BNSendGameData(id,prefix,text) id must be a game account presence id."

I've read a bit and seems that at some point this would have worked, but in fact

/run BNSendWhisper(1, "Aaa")

(1 was the self presence ID in that session, /dump BNIsSelf(1) returned true) now returns a chat message saying

"<my-battle.net-id> is not online."

Any idea on how to communicate information in this scenario?
