I have checked the connections several times and I am sure that the connected set of RPI and MAX3232 is according to the diagram https://ibb.co/5FS3sCV.
In Raspberry configuration I also checked /dev/ttyS0 and /dev/ttyAMA0 variants several times. UART support enabled in raspi-config.
I still have no possibility to control OAP from MMI button panel. I have no idea what could be wrong anymore. Maybe someone else can give me a solution.
