Electronic – Wifi Module over UART with STM32 mcu

embeddedjtagmicrocontrollerstm32uart

I am trying to integrate an off the shelf wifi module with STM32f2 mcu over UART interface.
I need to test the board after laying out the board. Is there a way I can test this UART interface before loading a binary to STM flash that talks to the WIfi module.

Can I do this communication (UART) testing using JTAG?

As far as I understood - you want to test WIFI module without hooking it up to a microcontroller.

In theory you could talk to it via UART directly from your computer using some USB-to-UART dongle, but probably WIFI module is quite a complicated beast, so this would involve amount of work similar to writing a program on a microcontroller.
