Hi,

You have not properly closed the existing connection. You need to wait until inactivity timeout occurs or close the connection when you close the application.

I propose that you close the connection to prevent this error.

The following code will do connect/close process. Please check and correct me if it is wrong. Thanks...

if (media != null) {
if (media.isOpen) {
// Close connection
close()
} else {
//Open connection.
initializeConnection()
}
}

@Throws(java.lang.Exception::class)
private fun close() {
val media = mDevice!!.media
if (media.isOpen) {
/ try {
readDLMSPacket2(mClient!!.releaseRequest())
} catch (e: java.lang.Exception) {
//All meters don't support release. It's OK.
}
val reply = GXReplyData()
readDLMSPacket(mClient!!.disconnectRequest(), reply)
/ media.close()
}
}

Hi,

Some meters expect that you must wait for a while before a new connection.

It's hard to say what might be the issue because I don't have your meter. Try to connect with GXDSLMDirector multiple times and if it the connection fails, you need just wait for a while before the new connection.
