When sending data from a Raspberry Pi device to Android, it does not receive any data

When sending data from a Raspberry Pi device to Android, it does not receive any data on the Android side. It gets a notification that there is data to be read but the data itself is not there as it says it is of size 0. When connecting with native methods instead it works fine so it appears to be a problem on the Qt side.

This happens when using the btchat/chat example, but appears to work when going from Android to Android and from Android to desktop.
