Hi,
I have a similar problem as the thread https://www.edaboard.com/threads/215743/.
I develop upon SIM5360-EVB_V1.03 and communicate through the UART (RS232) and UART2 (micro USB) to configure SIM5360. I want to develop a specific board with this chip and using only UART (RS232) as serial port to communicate AT commands and receive NMEA sentences. I did not read this was not possible, but I did not achieve doing it. I configured SIM5360 to allow either the transmission of AT commands through UART port or the reception of NMEA sentences. I would like to do both with the same port.
The following configuration allow to receive NMEA sentences only:
The following configuration allow to transmit AT commands only:
From https://www.edaboard.com/threads/215743/, I understand that uploading the factory reset firmware with the QDL utility could be a solution in case we corrupted the current firmware by inadvertence.
Does someone has a solution or has the SIM5360A factory reset firmware?

The following configuration allow to receive NMEA sentences only:
Code:
AT+CMUXSRVPORT=1,1 //DATA through virtual port 1
AT+CGPSSWITCH=2 //NMEA through UART port
The following configuration allow to transmit AT commands only:
Code:
AT+CMUXSRVPORT=1,5 //NMEA through virtual port 1 (NMEA port)
AT+CGPSSWITCH=1 //NMEA through NMEA port
