I've been having an issue with data integrity using an RFCOMM socket over Bluetooth in Android. I don't have any issues connecting, but the data I receive is garbled and not the same as the data that is sent. The data is sent by an RS232 device over a Bluetooth adapter, which the phone connects to. There isn't a problem with the adapter as the data is properly received if I connect with a laptop.
My Bluetooth connection is handled based off of the BluetoothChat sample application found at the Android developer site (http://developer.android.com/resources/samples/BluetoothChat/index.html), with no changes. The data being sent is plain text and control characters (which are stripped out before display to the user). The specific problem I have is that some of the text is missing, some of it is repeated, etc. The funny thing is if I connect to a computer with a terminal app and type in there, the data is transmitted fine. Additionally, if I connect to the device using the GetBlue app the data is received fine.
So I guess the issue is what does GetBlue possibly do different to handle its Bluetooth data transfer, or is there another way receive Bluetooth data over an RFCOMM socket on Android?
