Message duplication

[devindi]

Hello!

I faced with some issue.
I'm trying to send a number of messages through BT using this lib. My code looks like

for (Banner bannerItem : banners) {
                JSONObject bannerJson = new JSONObject();
                bannerJson.put("image",bannerItem.getImageUrl());
                bannerJson.put("position", bannerItem.getPosition());
                ALog.error("Do Send %s", bannerJson.toString());
                bluetoothController.write(bannerJson.toString().getBytes());
 }

Sometimes receiver app receives current item and previous one, e.g.
first message: {banner ob 1}
second message: {banner ob 1}{banner obj 2}
