Hello,
I can not connect to GSM with the Board.
Sim from "Things Mobile" APN: "TM" no PIN. The card words with a Board from MediaTek.
I use an antenna from Hologram Dash, which has the same u-blox chip on it. 2000mAh battery is connected
I tried some example sketches and have inserted:
MODEM.debug();
Everytime the data on serial port ends with:
+UMWI: 0,4
AT+CREG?
+CREG: 0,0
OK
AT+CREG?
+CREG: 0,0
OK
AT+CREG?
+CREG: 0,0

+CREG: 0,0

AT+CREG?
+CREG: 0,0

AT+CREG?
+CREG: 0,0

AT+CREG?
+CREG: 0,0

Then nothing more happens.
This is the result of example Sketch "GPRSUdpNtpClient"
can someone help?
