こんにちは、登録したばかりの Android デバイスで mqtt に接続しようとしていますが、エラーが発生し続けます
Not authorized to connect (5)
これは私のコードの一部です
client = new MqttAndroidClient(context, connectionURI, clientID);
client.setCallback(callbacks);
String username = IOT_DEVICE_USERNAME;
char[] password = this.getAuthorizationToken().toCharArray();
MqttConnectOptions options = new MqttConnectOptions();
options.setCleanSession(true);
options.setUserName(username);
options.setPassword(password);
Log.d(TAG, "Connecting to server: " + connectionURI);
try {
// connect
return client.connect(options, context, listener);
} catch (MqttException e) {
Log.e(TAG, "Exception caught while attempting to connect to server", e.getCause());
throw e;
}
ここで、IOT_DEVICE_USERNAMEはストリング「use-token-auth」 であり、connectionUriは「tcp://<"organization">.messaging.internetofthings.ibmcloud.com:8883」です。
他に興味深いのは、このエラーの直前にこのログを取得することです
Unregister alarmreceiver to MqttServiced:<"organisation">:<"DeviceType">:<"deviceId">
これがエラーのstackTraceです
