Hi everyone. Now, I’m trying to send AT command from the PC to the WP7609 module over UART1. But I am not received any response data. I use the module USB_To_TTL (FT232). I checked and have had 1.8V on the VGPIO pin. Does everybody know? and how to fix it? Kind regards!

I don’t see problem, you can see below:

Have you set AT!MAPUART?
