SIM 7000 Arduino Board

Hello,

i have Problem to use the board with Arduino.
If i use the Script the Modem did not answer.
I Think that is that the software serial port only goes up to 38000 baud and not up to 115200.

With the onboard USB nothing happend the computer found nothing althoug i use external 5V vfom Arduino to power up the module.

Who can help me to set the baud rate to 19200?

Thanks

 Hi, sorry for late reply and thanks for your support.
The NET light is not lighted which indicates the SIM7000 is not turned ON.
Please check whether the external power supply is within the range 7-12V. The USB cannot offer the power that SIM7000 needs.
Can you please confirm that the external power should be supplied to the VIN pin (12v+ve) and GND pin (12v -ve) userHeadPic verenicolson
