Dear alll,
I am using airprime WP7104 module .
I am trying to connect to the airvantage cloud .
I have registered the module IMEI number in the site.
I am trying to follow the steps given in http://www.legato.io/legato-docs/15_01_1/connecting_air_vantage.html#overviewAVIConnec
I am right now struck at the telnet part … where i give the command as
telenet localhost 2000its not connecting and giving error as “cannot connect to remote host”
Kindly help me out
Regards
Shruthi
Do you run
telnet localhost 2000on your dev computer or the WP7104?
You must run it locally on the WP7104.
Dear Krima,
Thanks for replying
I am running the telnet locally in WP7104 only .
kindly find the error below
root@swi-mdm9x15:~# telnet localhost 2000

Hi Shruthi,
Can you make sure you are running the latest firmware (06.03.39.00) and legato (15.01.0.Beta)? I suspect that the version mismatch is causing you to see the “Connection refused” error above.
And no, you will not need a SIM to “telnet localhost 2000”, but you will need a SIM with a working data connection to connect to the cloud.
Thank you,
Enoch
Hello Enoch,
Thanks for replying …
I tried the do the firmwarew update as my currect firmware is 06.03.32.00 .
i followed the fwupdate as mentioned in legato site .
i gave the
fwupdate <target IP>.
I am not able to continue as i am not getting any response.
Regards
Shruthi
Hi Enoch,
Thanks for suggestion, i have updated the firmware as advised by you and now am able to telnet.
I have changed the URL also. But still i m unable to connect. When i am requesting a connection by giving command:
“:agent.srvcon.connect()”
It shows output as:
“timeout expired, unable to request connection”.
Can you please tell me where i am going wrong.
Thanks
We also checked the data connection profile but data connect doesn’t happen .This is with a sim that has data connection.
root@swi-mdm9x15:/# cm data
Index: 1
APN: airtelgprs.com
PDP Type: IPV4
Connected: noroot@swi-mdm9x15:/# cm data connectThis fails
This can happen for multiple reasons such as incorrect data connection profile (wrong apn), not registered on network etc…
Can you provide the logs of ‘cm data connect’ failing? (logread)
Also can you check if your SIM is in the correct state and if you are connected to the network?
root@swi-mdm9x15:~# cm sim
SIM card is inserted and unlocked (LE_SIM_READY).
e.g.
root@swi-mdm9x15:~# cm radio

root@swi-mdm9x15:~#Can you try just starting a data connection using ‘cm data connect’? If it does not work, can you send me the logs?
Also do you have an antenna attached to your module?
Thanks,
Enoch
hello enoch
Find the log belw for cm data connect
root@swi-mdm9x15:~# cm data connect
Connected through interface ''
Disconnected
root@swi-mdm9x15:~#I have not connected any antenna
The logs I’m looking for are located in ‘logread’. After you run ‘cm data connect’, stop it and run ‘logread’. You will see an output of all the legato logs. Can you copy that content into a file and place it here?
Also, can you try attaching to your module?
THank you,
Enoch
hello ,
PFA
i tried with both i.e with and without antenna but the behaviour is same. I am attaching here the log read for both the cases.
Hi Shruthi,
It looks like the attachment system is broken, I will send you a PM with my contact information to send these logs to.
Thank you and sorry for the inconvenience,
Enoch
