You recommend that unused IF can be used as GPIO function.
If just one GPIO is missing, how about using the previous recommendation to control UART2 RTS/CTS pins just like what we suggest in the forum for UART1?
- using linux generic API ioctl() to control UART2_CTS which is stated as output pin in PTS.
- using AT command “AT!entercnd=“A710”;!BSGPIO?14” to read the UART2_RTS status which is stated as input pin in PTS.
We try to control as GPIO function in UART2 IF, but we don’t know the way how to set AT command/legato command to operate it.
Could you tell me AT command and legato command how to set, in order to control as GPIO function in UART2 IF?
