Im using ESP8266 freertos sdk. esptool.py v2.4.0. Im using AP mode and HTTP server to access webpage. However, the webpage can only be access after 5 cycle. Seems like some socket is not properly closed and caused httprx_tx error. Below I describe my cycle.
1- Init AP mode & create webpage
2- Connect with PC
3- Submit Button
4- Deinit AP mode & delete webpage
5- Go to step 1
Below is my code
Code: Select all
