I have successfully connected the Arduino MKR1010 WiFi and published data to the Arduino Cloud, Dashboard and Phone widgets.
I am now trying to do the same with an Arduino MKR1500 NB-IoT. I am using a Hologram Sim. I can clearly see the Hologram SIM is connected through their dashboard to AT&T or TMobile depending on if I'm at my house or office. There is data sessions and some non-data sessions.
I can not get this device connected to the Arduino Cloud. I am using their APN = hologram with no pin, username or password. I have edited the Things Properties page to reflect:
NBConnectionHandler ArduinoIoTPreferredConnection(GPRS_APN);
At this point, I am using only the #include <BQ24195.h> to read battery life. I have a boolean for battery state, I am using cloudTime, and cloudLocation with fixed or static long, lat. All of this worked just fine on MKR1010.
