Hi i want to use SPWF01SA wifi module, but i'm confused about connections. 

 I want to control SPWF01S with another mcu and in my schematic i've connected only rx,tx, vcc and gnd also one connector like jtag. But i did not understand how to program module ? My jtag connections right ?  In SPWF01SA with nucleo board schematics, there is a connector like a jtag. (Below

) I need help about connections with my mcu and also RTS and CTS pins. I write details below pictures. My design is

  I'm sure that, there are forgotten connections. 

With warmest regards.

Hi Gerardo,

Thanks for your prompt reply and kind advice. So any tool for JTAG download? Or may I know your suggestion for mass production pre-programming? Thanks a lot.

It depends on which HW devide you are using for SWD/JTAG. Example: ST-Link & 'STM32 ST-Link Utility'

Hi Gerardo,

We are using UART for programming and testing but hope to know the JTAG way for mass production. Please advise. Thank you so much.
