Trouble streaming Data to Arduino UNO from SIM7600CE

I am having trouble streaming data to serial port from SIM7600CE to Arduino UNO. Do I need to use jumper cap for RX/D1 and TX/DO, or RX/D8 and TX/D7, or use jumper lead from SIM7600CE to corresponding ports on Arduino UNO ports?

Please help.

Hi Michael,

Have you had a look at the product wiki, In there it specifies that you need to jumper the D0/D1 or D7/D8 depending on how you are using the controller board. to follow their example they are using you need to jumper D7/D8.

Hi Clinton,

Thanks so much for following up. I found that information yesterday. I am to use D7/D8.

Regards, Michael.
