how to use binary sensor make VOICE CALL by SIM7600E 4G module in ESPHome

1. what's your KC868-A2 pcb version? take a photo.
2. sure, you can use SIM7600E connect to cloud server by MQTT.

1) It is A2 V2.4.

I tested the module using the latest firmware 2.2.10 and using your own interface I can send a message and call my phone so I know the module works and the SIM does as well.

I want to do the same but using our ESPHome code we have implemented but I am not sure if the pinout is correct and also I can simulate buttons and I see the AT commands coming in but no output and unable to test AT commands.

I am also unsure on how to test if it is working or connecting using only the SIM connection to the internet other than making some mqtt configuration messages.

Code:

button:
  - platform: template
    name: "Call Button"
    on_press:
      then:
        - uart.write:
            id: uart_sim7600
            data: "ATD[phone number];\r\n" # Replace with the phone number to dial
 
  - platform: template
    name: "Send SMS Button"
    on_press:
      then:
        - uart.write:
            id: uart_sim7600
            data: "AT+CMGF=1\r\n" # Set SMS to text mode
        - delay: 1s
        - uart.write:
            id: uart_sim7600
            data: "AT+CMGS=\"[phone number]\"\r\n" # Replace with the recipients phone number
        - delay: 1s
        - uart.write:
            id: uart_sim7600
            data: "testdevice-02\x1A" # Send the message and terminate

---

So apparently this is the proper pinout for the GSM in the A2, which is different than the one on this website https://devices.esphome.io/devices/KinCony-KC868-A2:

Code:

- id: uart_sim7600
    tx_pin: GPIO5
    rx_pin: GPIO13

Also I don't know if this also was needed but it works for me but in this code of one of your examples 

Code:

- platform: template
    name: "Call Button"
    on_press:
      then:
        - uart.write:
            id: uart_sim7600
            data: "ATD[phonenumber];\r\n" # Replace with the phone number to dial

In [phone number] I also added the area code of the country.

I could recieve a message and a call using button components to simulate the press of a button.

EDIT: MY NEW ISSUE IS THIS: I need to be able to get this device running connecting to the internet using a 4G/LTE connection. I can receive messages and calls and I can send them using your software and ESPHome but as far as I know there is no 4G connection integration with ESPHome so I assume this must come from an external component.

Do you have anything at hand you could help me with for this?
