Kotlin not receiving a full packet from an HC-06 Bluetooth module - kotlin

Question

In Kotlin I am having an issue with data not fully loading into the buffer in Android in one packet. I am sending <7:16> data packet from a HC-06 bluetooth module.
When i receive it's coming in as 2 packets. The micro is sending a CR and LF and the end of the transmission.
I/UI_Msg: <
I/UI_Msg: 7:16>
I/UI_Msg: <
I/UI_Msg: 7:16>
etc
If I add a sleep command for a second, then query the buffer it comes in completed in one packet. The problem is I want to send more than one packet in a second..
How can i fix this issue to or can i just build a string until '>' is received from the buffer.
private fun beginListenForData() {
val handler = Handler()
stopThread = false
buffer = ByteArray(10)
val thread = Thread(Runnable {
while (!Thread.currentThread().isInterrupted && !stopThread) {
try {
val byteCount = inputStream!!.available()
if (byteCount > 0) {
//Thread.sleep(1000) // wait for buffer finish filling
val rawBytes = ByteArray(byteCount)
inputStream!!.read(rawBytes)
val string = String(rawBytes, StandardCharsets.UTF_8)
//handler.post {txt_message.text=""}
Log.i(TAG,""+ string)
//handler.post {txt_message.append(string)}
// processInput(string)
}
} catch (ex: IOException) {
stopThread = true
}
}
})
thread.start()
}

Figgured it out. Read the buffer one byte at a time and build the string character at a time. Check for the < and the > character for a valid transmission
private fun beginListenForData() {
stopThread = false
val thread = Thread(Runnable {
while (!Thread.currentThread().isInterrupted && !stopThread) {
try {
val byteCount = inputStream!!.available()
if (byteCount > 0) {
val rawBytes = ByteArray(1)
inputStream!!.read(rawBytes,0,1)
val string = String(rawBytes, StandardCharsets.UTF_8)
if (string== "<") {
m_Headder=true
}
if (m_Headder==true){
stringBuilder = stringBuilder.plus(string)
if (string ==">") {
m_Received=stringBuilder
Log.i(TAG, "string:" + stringBuilder)
stringBuilder = ""
m_Headder = false
ProcessMessage(m_Received)
}
}
}
} catch (ex: IOException) {
stopThread = true
}
}
})
thread.start()
}
