We are working on Sodaq SARA AFF R412 module for connectivity to the NBIOT network. Previously we were able to connect the module with 2G network and able to display the data. But when tried with the NBIOT sim for connectivity, we failed to connect.
Also, we installed Universal tracker for displaying data to the maker.allthingstalk.com website.
In code, I changed the values as follows
#define DEFAULT_APN “duiot”
#define DEFAULT_FORCE_OPERATOR “42403”
#define DEFAULT_BAND 524416
In serial monitor, we gave the following settings:
att= 4mMXXXXX ( Device token of allthingstalk.com)
Though giving all the above settings, it seems to be not working .
Please help us to figure out the problem in connectivity to NBIOT. Let us know if we missed out any settings.
