I have a GPS module connected vía UART in the GPIO. Now I want to add a GSM module to my proyect but my TX RX pins are busy with the GPS. I saw an adapter to connect the GPS through USB with a UART USB adapter and use the ttyUSB0 in the raspberry Pi 3 to receive the GPS data. Can I receive the GPS data with the ttyUSB0 and the GSM through the ttyS0 at the same time connecting the GPS module via USB and the GSM via GPIO ??
Thank you, and sorry for my english.
