SIM7000 - Serial interface getting "Faile to set baud rate" using example code [2nd attempt]
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I'm using the example code from the Wiki here: https://wiki.dfrobot.com/SIM7000_Arduino_NB-IoT_LTE_GPRS_Expansion_Shield_SKU__DFR0505_DFR0572
and it's not able to set the baud rate.
The error message is “Faile to set baud rate” (sic)
I've followed the HW & SW requirements exact and used the example code without modification.
Do I have a faulty device, or am I missing something?

Thanks!

I think the baud rate is not set to 19200. To set the baud rate to a desired value, you have to use the AT command
AT+IPR=<rate>
