Hello Adruino friends,
I would like to hook up a small project. In need this for resetting my firewall at home because it's doing strange stuff from time to time. I followed the instruction of the GSM shiel to hook it up and to see if I get this running. The goal is to send a SMS to my mobile phone. I should see if the test before hand are good. Unfortunately it's not doing well.
UNO replica board: mikrocontroller board with ATmega328P, ATmega16U2, compatible with Arduino UNO R3
both boards have their own 5 V 10 W power supply
gnd connection between them
changed the jumper on the UNO for software serial
software serial connection on Pins 7 & 8 on UNO -> crossed connection to the GSM shield
use official Adruino IDE on Windows 10 and Debian
used this code to send SMS
changed TX und RX ports to 7 and 8 in GSM.ccp like:
//De-comment this two lines below if you have the //second version og GSM GPRS Shield //#define _GSM_TXPIN_ 2 //#define _GSM_RXPIN_ 3 #define _GSM_TXPIN_ 7 #define _GSM_RXPIN_ 8
compiled and uploaded
power both boards up
- hit power button on GSM shield
- look in serial monitor
Error: The GSM shield can't log into the net: The net LED indikcates this. On the serial monitor in the Adruino IDE I get this:
GSM Shield testing. ATT: OK RIC: ⸮⸮⸮⸮ ATT: OK RIC: ⸮⸮⸮⸮ ATT: OK RIC: ⸮⸮⸮⸮ ATT: OK RIC: ⸮⸮⸮⸮ ATT: OK RIC: ⸮⸮⸮⸮
I could not find any final solution on my search. Do you have any ideas?
I appreciate any kind of ideas or crtitic.
