I have a Sodaq SARA AFF N211 connected by vodafone with his vodafone SIM card.
I'm in Barcelona, I can connect my board over NB-IoT (I think) when I send :
AT+COPS: 1,2,"21401",9 it works and i'm connected to the network, If i send AT+CSQ the module returns me signal (around 15/16 something like that).
I open my socket AT+USOCR=17,200 and send a packet thank to AT+USOST=0,"126.96.36.199",20000,11,"4e422d496f543031303030"
I checked the consumption profile and it's OK, the frame is sent.
my question is :
I can connecte my device ONLY with this APN : nb.inetd.gdsp if I change for another one it doesn't work
with this APN my frame is sent but I don't received in my server. it might be an APN issue
What is the right APN for Vodafone spain ?
