KISS FEND Newline 192 c0 Bug

[na7q]

So after some debugging with VARA and the developer. Jose has discovered that APRSDroid creates a new line after the first byte of c0.

Instead of the KISS data being one single line, it's c0, newline, then the rest of the data.

This actually causes VARA to crash.

I have a script that shows the raw data from APRSDroid. As you can see, two lines, followed by the actual packet itself. c0 should be with data seen on line 2. Creating 1 line.

I have found this problem before, the app will crash VARA after sending kiss packs again.

Indeed. Jose (VARA dev) is aware, I have already tested the unreleased version of VARA that fixes this. It should be released within the next day or two. We are working on a couple other minor fixes for the HF modem. I believe the FM version is fixed and released already.

VARA authors have released a new version.

This code resolves that issue.

def writePacket(p : APRSPacket) {
    Log.d(TAG, "writePacket: " + p)
    val combinedData = Array[Byte](Kiss.FEND.toByte, Kiss.CMD_DATA.toByte) ++ p.toAX25Frame() ++ Array[Byte](Kiss.FEND.toByte)
    os.write(combinedData)
    os.flush()
}
