KC868-A2 and SIM7600

[cillgen]

Hi,

Has anyone managed to get a SIM7600 module to work on the  KC868-A2 device ?

ESP32 TX pins shall be PIN34 but this pin in defined as "input only" in ESP32 documentation.
So software crashes on begin function (error "tx_io_num").

Thanks !

It works now, with the help of @Admin

For those who have the same issue (PCB v2.3) :

• Add a wire between GPIO5 and TX (see picture)
  
• Change your software : RX=13 Tx= 5
