- My goal is: Establish Commuication from TTGO-TCALL V1.3 to GPS module (NEO 6M) via TX and RX pin on TTGO-Tcall
- My actions are: use deafult UART0,1,2 from mongoose OS
- The result I see is: Cannot get GPS data from the GPS Module, I cannot use UART0 because it is used for communication with Mongoose OS serial, Cannot Use UART1 because it is used by SIM800L, Cannot Use UART2 becuae pin 16 and 17 is not present on TTGO Tcall
- My expectation & question is: How to solve set TX and RX Pin at TTGO Tcall to communicate with GPS Module (i.e. how to use other GPIO pins as UART channels)
EDIT: I use this library for GPS https://github.com/alvarowolfx/gps/
