The init modem works very very well, but always finish on CONNECT. I can see the modem sending the ppp data, but, nothing more happens, then the ppp app send again +++, got no CARRIER, and repeat the PROCESS of init until CONNECT, and again and again! Is that a problem of RTS CTS that i am not using between ESP32 and MODEM ? Or other problem ? Can you give me some TIP ? If possible test there without HANDSHAKING. Thank you so much!
