FTP with PLS8 and UART. | Telit Cinterion IoT Developer Community

We have a product based on the PLS8 with a UART connection to a microcontroller. UART operation seems to require using the CMUX multiplexer if for instance, GPS data is required. Currently, through the multiplexer we have:
Channel 1 - Modem Interface
Channel 2 - Application Interface
Channel 3 - GPS NMEA data
Channel 5 - Transparent TCP/IP service
Channel 6 - Transparent TCP/IP service
Is there a way to also add FTP service for uploading a file to a host server to those existing multiplexer channels? We require simultaneous TCP and FTP connections.
Alternately, is it possible to send AT commands, receive responses, get GPS data, transfer data via TCP and upload a file using FTP that doesn't rely on the CMUX multiplexer when using the PLS8's UART connection?
Thank you,
Hello,
If you use IP services over AT commands you can use for example one of transparent channels to transmit data over transparent socket connection controlled on modem interface. You can also use FTP connection on modem interface. You should also be able to control 2 non-transparent connections with AT commands on one interface. As for GPS NMEA data it can be printed to the dedicated NMEA port or redirected to interface configured for URCs. However it may not be convenient to have NMEA on the same interface as all other logic.
