Android Libary - No response for association request

Hi Mikko,

we are using android library. library works with non ciphered meter whereas with ciphered meter we are not getting response for assocation request. please correct the flow if we are doing mistake. attached tx and rx log along with code snippet.

client = new GXDLMSSecureClient(true, 16, 1, Authentication.NONE, "", InterfaceType.HDLC);
client.getCiphering().setSecurity(Security.NONE);
client.setAuthentication(Authentication.NONE);
command_obtained = client.snrmRequest();
for (byte[] it : client.aarqRequest()) {
command_obtained = Arrays.copyOfRange(it, 0, it.length);
break;
}
byte[][] tempS21 = client.read(readInvocationCounter, 2);

for (byte[] it : tempS21) {
command_obtained = Arrays.copyOfRange(it, 0, it.length);
break;
}
command_obtained = client.disconnectRequest();

client.setUseLogicalNameReferencing(true);
client.setInterfaceType(InterfaceType.HDLC);
client.setClientAddress(48);
client.setServerAddress(1);
client.setAuthentication(Authentication.HIGH);
client.setPassword("0000000001035820");
client.getCiphering().setSecurity(Security.AUTHENTICATION_ENCRYPTION);
try {
client.getCiphering().setSystemTitle("ABCDEGFH".getBytes("ASCII"));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
client.getCiphering().setBlockCipherKey(GXCommon.hexToBytes("31323334353637383930313233343536"));
client.getCiphering().setAuthenticationKey(GXCommon.hexToBytes("31323334353637383930313233343536"));
client.getCiphering().setInvocationCounter((Long) invocationCounterValueDLMS++);
System.out.printf("invocationCounterValueDLMS is %d\n", invocationCounterValueDLMS);
client.setAutoIncreaseInvokeID(true);
for (byte[] it : client.getApplicationAssociationRequest()) {
command_obtained = Arrays.copyOfRange(it, 0, it.length);
break;
}
