  * File  : DFRobot_SIM7000_ATtest.ino
  * Power : SIM7000 needs 7-12V DC power supply
  * Brief : This example use the serial port to send AT command to control the SIM7000
  *         With initialization completed, we can enter AT command to SIM7000 directly
  * AT command list:
  * https://github.com/DFRobot/binaryfiles/raw/master/DFR0505/doc/SIM7000%20Series_AT%20Command%20Manual_V1.01.pdf
  * Note  : If you use Mega please connect PIN8 PIN10 and set PIN_RX = 10
  *         The AT command must end with CRLF
