UART with HL7618


My design is based on mangOH Green and I am using HL7618.
I would like to use UART communication from the microcontroller to control the HL device.
Does connecting the HL and micro using UART work directly?
Is there any specific setting required?
In the custom board, I have the access to UART Tx and Rx only.
Also let me know, what is the initial test to understand the HL device is working.



I found this line in the technical specification “Either UART1 or the USB interface could be used to send AT commands” (I believe both communications are available by default) for HL7618. So, now I am clear that, I can communicate with HL through UART1 port directly. But, does it support just 2 line communication without doing any configuration (+KSLEEP=2) update?
