[SOLVED] Sara fails to connect

[pe1mew]

One month ago my SARA connected without problems to T-Mobile and AllThingsTalk.
Today I powered the same SARA board and it failed to connect.
When running trought the tutorial at http://support.sodaq.com/sodaq-one/at/ I do not successfully pass command "AT+CGATT?". It always returns: "+CGATT: 0" e.g. connection failed.

While studying varoius examples I found that a new connect string was used.
The one I used was:

if (nbiot.connect("oceanconnect.t-mobile.nl", "172.16.14.22", "20416"))

While the other one I found is:

if (nbiot.connect("cdp.iot.t-mobile.nl", "172.27.131.100", "20416"))

My questions are:

• Is there a way to verify if my SIM is operational?
• was there a change in conect method?
• has anyone experienced the same issue?
• is there a solution?

Now I have a aplication for my board this summer I would like to use it.
Thanks in advance.
Cu, Remko.

Dear Remco,

Can you send me your SIM number? We need to move it to the new Nokia Impact.
I hope all your other questions are answered here: http://support.sodaq.com/sodaq-one/t-mobile-nl/
Let me know if you have anything else

Kind regards,
Jan

Just to keep the thread up to date:

The early adopters have recieved an connection to the “old” Huawei’s OceanConnect platform.
On the 1st of May 2018 OceanConnect has been replaced by Nokia Impact.

I am currently in the process of migration and keep you posted.

Small update.

Today T-Mobile moved all OceanConnect simcards to Nokia Impact.
So no need to email me your simnumbers anymore

Yesterday I got the confirmation that I was migrated.
A test today gave me: "Connected succesfully!" from my Sketch while using this pice of code and all other required changes:

// New connect string according to: http://support.sodaq.com/sodaq-one/t-mobile-nl/
if (nbiot.connect("cdp.iot.t-mobile.nl", "172.27.131.100", "20416"))

Now lets continue with the stuggle to get my data out again.

[pe1mew]

The past days happend the following:

• I have received form T-Mobile the credentials to access the API trough Postman.
• T-Mobile migrated my SIM to the new platform.

After numerous sending of commands using Postman I was able to send my data to the North-Application.

I conclude that documentation is poor (optimistic statement) if there is any.
Although I did not intend (yet) a T-Mobile installfest I was able to get my data out.

@pe1mew

I am happy you were able to get your data out
I agree that the documentation is a bit poor at this moment.

Did you know T-Mobile have a manual on their forum?
https://forum.iot.t-mobile.nl/category/19/early-access-impact-platform-test

Do you have some feedback about the information sodaq needs to add?

Kind regards,
Jan
