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

December 6, 2018 - 10:16am, 1002 views

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,
