I am trying to connect leshan demo client to https://leshan.eclipse.org/bs/ using below command but keep getting below message

Command(tried both hex & ascii value): java -jar leshan-client-demo.jar -u leshan.eclipse.org:5784 -b -i 866971030000710 -p 1234 -n vin2client -lp 49665 Error Message:

I look at https://leshan.eclipse.org/bs and search for your endpoint name and I didn't find the same credentials.

coaps://leshan.eclipse.org:5784
security mode : PSK
Id :  866971030000710
secret :  31323334

Just tested with it and it works for me :

Device does succeed to register to leshan.eclipse.org because LWM2M Server config credential does not match with leshan.eclipse.org credentials setting : https://leshan.eclipse.org/#/security. (Bootstrap say unsecured connection and lwm2m server expect PSK for "vin2client" endpoint name)

Hi,

Today I had created below details in Step1: https://leshan.eclipse.org/bs/

Client Endpoint | LWM2M Bootstrap Server |
vinClient4 | coaps://leshan.eclipse.org:5784security mode : PSKId : 12345 secret : 31323334

LWM2M Server coaps://leshan.eclipse.org:5684security mode : PSKId : 12345 secret : 31323334

Step2: In Gateway created below https://leshan.eclipse.org/#/security

Client Endpoint | Security Mode | Security Information

vinClient4 | Pre-Shared Key | Identity : 12345Key : 31323334

Step3:

Using below command started the client java -jar leshan-client-demo-1.0.0-M10-jar-with-dependencies.jar -b -u leshan.eclipse.org:5784 -n vinClient4 -i 12345 -p 31323334

Step4:

Getting below exception. 2019-01-17 11:34:21,694 INFO LeshanClientDemo - Press 'w','a','s','d' to change reported Location (-18.0,-29.0). 2019-01-17 11:34:21,694 INFO LeshanClient - Starting Leshan client ... 2019-01-17 11:34:21,694 INFO LeshanClient - Leshan client[endpoint:vinClient4] started. 2019-01-17 11:34:21,694 INFO RegistrationEngine - Trying to start bootstrap session to coaps://leshan.eclipse.org:5784 ... 2019-01-17 11:34:22,056 INFO CaliforniumEndpointsManager - New endpoint created for server coaps://5.39.83.206:5784 at coaps://0.0.0.0:57718 2019-01-17 11:34:53,189 WARN RegistrationEngine - Unable to send Bootstrap request : handshake flight 1 timeout!

I am unable to narrow down what exactly I was missing. Please let me know. Whether my steps are in order sequence.

Just tested on my side with master :

It works for me.

Also tested with M10 version, it works for me too.

I suppose this is network issue on your side. By the way the log says that the DTLS handshake timeout on flight 1. So this means thats you never receive a response from the server even at DTLS layer which would confirm a network issue.

You could use wireshark to know what happen at network layer.

Should we close this issue ?
