This method can be used with other Serial softwares, e.g. DF Serial Debugger by Lisper), clike here to know more detals about how. But if you have inserted a SIM card onto the module, you do NEED an external power then, a mere USB power is NOT capable to run it! You can also use them both at the same time, just leaving the switch in the middle and use code to enable GPS/ GSM alternatively. NOTE: Version difference from V1 to V3 GSM high-gain antenna has been removed GPS/GSM UART selection has been replaced by a Three-position Switch: UART Select. This way you can let the GPS enabled while using GSM network. Please go to the section below, «Ways to send Ctrl +Z in Coolterm», for more details.
Contents Introduction This is a GPS/GPRS/GSM arduino shield from DFRobot. After the STAT LED is on, and some RDY(ready) notices printed on your screen, then you could send AT commands to use the module. For Q8. Using Leonardo for GPS debug with AT command Q8. I used Leonardo with the sample codes in this section «How to drive the module via Arduino board», also I changed the Serial.xxx() to Serial1.xxx() to adapt to Leonardo, and it worked. Corresponding answers to AT commands in GPS session Serial monitor in GPS mode via USB port NOTE: What is the meaning of GPS data received? And «Take off the jumper caps» do the same function as «slid the switch in the middle». 3. LEDPWR: To indicate if the module get power.STAT: If the module is enabled, it will turn on, this means that the module is running correctly. What’s the problem with it? A. Once the module detect the serial signal_Reset, it will reset, then the module would power down, namely the State and NET LED would turn off.
Please refer to Location Mapping (GPRMC), you could also go to FAQ>Q2 for more info. Then you will see «OK». After several seconds, the receiver should get a message from this shield. More Shopping from SIM 908 GPS/GPRS/GSM Shield For Arduino or DFRobot Distributor. But in this section «Drive the module via USB port (AT command)», what should I do? A. Hi, you are right that to modify the Serial into Serial1 for Leonardo using the sample sketches.
