Description
I'm sorry.
I'm not familiar with it and I'm not good at English, so I closed the previously posted issue by mistake, so please understand that I'm uploading it again.
1, After updating the sketch I worked on in version 2.0.9 to 2.0.14, I just recompiled and uploaded it without modifying the code and tried to connect to the AP, but I could not connect because the password was wrong.
-
If re-download version 2.0.9, it will work fine.
-
Change the version to 2.0.14 again and upload. At this point, can access it by selecting erase all flash before sketch upload: Enabled and Uploading.
The big problem is that it is not easy for people to access what is installed on other devices.
If you want to reproduce this problem
- Prepare versions 2.0.9 and 2.0.14
- Change to 2.0.9 and Enabled erase all flash before sketch upload
- After uploading the sketch, check the connection with the AP
Assuming it is installed in a high place out of reach - After changing to 2.0.14, compile and update with OTA or disable erase all flash before sketch upload
- Check AP connection
