Hello

I need to update the firmware (need the 1 command the is in release 3.3)for the above module. I have contacted the local ST agent and have received the required programs and files for the upgrade (via usart)

(SPWF01S Wi-Fi documentation package W48 - FW3.3)

I run the FW_update.bat file and do what is required including (BOOT0 pin needs to be pulled high (3.3v))

I always get a 'Initial ACK not received from module'' response error.

Question: I run the serial port just with Rx,Tx and Gnd. Do I need RTS and CTS?

Please note my serial comms can communicate with the module normally.

Hi Gary,

usually, when I see that error, means I did not provide module a reset AFTER boot pin has been pulled high.

Tx+Rx+GND are enough. Do not forget to provide 3V3 to module :)

Let me know.

ps: if you are moving to FW3.3, I really suggest you to move directly fo FW3.4.

Jerry

I sorted a day after you posted this.

I had a corrupt software download.

Thanks for the help.
