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.
