I tried a search for this question and I cannot find an answer. How do you update the firmware on the SPWF01SA? I need to know what pins need to be set in which direction. For instance, the datasheet only mentions the BOOT0 pin needs to be high but then it does not explain the update process other than it can be done via UART or FOTA. The AT command manual tells you what command to use if you want to update via OTA but is does not detail the process as to where to get the firmware, what pins need to be in which direction, etc. It also mentions about a HW factory reset (GPIO0 enabled). What is the nature of this pin and why is it needed?


I found another link in the ST community (SPWF01SA firmware update issue ) that talks about having issues and they mention FW_update.bat but not where to get it.


I hope there is a simple explanation as to how to update either via UART or FOTA. If there is anything that I have overlooked, please point me in the right direction.


Thank you in advanced.
