Hello, I got another MKR GSM 1400 and after a while of not knowing what to do with it I just wanted to read some SMS and look for some bit of text in the SMS. The problem is that instead of returning the message as my last 1400 did it returns: +CMGL: 1,"REC UNREAD","MyNumber",," The code to read…

Do a downgrade of the board core to 1.8.9. The sms read sketch doesn't work with 1.8.11. There is a bug in communication with MODEM in 1.8.11
