Just received my MKR NB 1500 board. Tried the SendSMS sketch with my Hologram SIM and it works fine. Tried the ReceiveSMS sketch and it says connected NB Initialized, waiting for messages, however nothing is received.
So I loaded the SerialSARAPassthrough sketch to get the modem version (ATI9) but I get no response on the serial monitor.
How can I get the modem version?
