A beginner at the beginning, how to flash ESP01 to latest AT firmware?
Posted: Mon Jul 25, 2022 3:03 am
I have an ESP01 module, which as a rather old firmware image...
I have downloaded the flash_download_tool_3.9.2.zip file and run the exe, but the window presented is NOTHING like the documentation I found on the expressif web site for flashing, so this has left me quite confused. Is there newer documentation?
I have the correct com port and baud rate set. because I get what appears to be the correct detected info for the ESP01 module I have. But I have no idea which AT binary files to download, nor what the SPI download configuration should be?
Please help. Every single Google reference I find appears to be years out of date!
Code: Select all
Type 'AT' Then Ctrl-M Then Ctrl-J
AT
OK
Type 'AT+GMR' Then Ctrl-M Then Ctrl-J
AT+GMR
