Hi, If the lwm2mclient is the same as the wakaama example one, this is a very basic command line interface. The registration to the LwM2M Server is not immediate. Thus the commands in the input file are probably coming too soon. Regards David Navarro De : wakaama-dev-bounces@xxxxxxxxxxx [mailto:wakaama-dev-bounces@xxxxxxxxxxx] De la part de Giuseppe Sofo

Objet : Re: [wakaama-dev] (no subject) I run the client with the following command: ./lwm2client -4 -h "server IP" -n arduino_yun < command_file.txt where command_file.txt is the file where i put commands such as "change /3/0/9 50". But I get the message showed in attached image. I have another problem. I'm trying to run the client by sketch using Arduino Yun's bridge libraries. So, the client connetcs using the command runShellCommandAsynchronously, but, after, when I send command using println (like that Process.println("change /3/0/9 50"), nothing happens. This problem is enough famous on web: in particular it is known by who use Wakaama through bridge libraries. 2017-06-21 9:49 GMT+02:00 David Fernández Ros <davidfr@xxxxxxx>: Hi Giuseppe, Maybe the scripts are out of date compared with the current wakaama implementation. Try adding new compilation flags such as 'LWM2M_CLIENT_MODE' after line 88 in '1.prepareCompilation' script: echo "add_definitions(-DLWM2M_CLIENT_MODE)" >> wakaama/examples/arduinoyunclient/CMakeLists.txt" Hi, I'm Giuseppe from Italy and I'm working on a project about Wakaama and its usage on embedded device. I'm trying to setup a connection beetween a Wakaama client on an Arduino Yun device (installed using WakaamaCCTools provided here https://github.com/HOP-Ubiquitous/OMA-ArduinoYun/tree/master/wakaamaCCTools) and a Wakaama server compiled on Ubuntu 17.04. While the server is running correctly, when i try to start a connection from the client (connecting to Arduino with SSH) I get the following error: 
I have tried to install a client on Ubuntu and that one works fine with the server on the same machine. I'm using ipv4 on both side. Can you help me to find a solution to connect the client on Arduino? _______________________________________________
