KC868-A2 and SIM7600 - cillgen - 01-11-2024
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
