I looked at the TelnetStream but was none the wiser… My main issue is making settings changes persistent. I have seen examples of actions like toggling LED:s etc, but none thta saves data into some permanent location and applies the data to the running process.Īlso I have not seen any webserver sketch that can handle both a config page and an active serial port server. Is there some good example of a basic webpage with entry boxes and a button for activation requiring some kind of activation code? Should give much better performance than interpreted solutions. I have found one for the NodeMCU interface but I'd much rather use the Arduino IDE and compile a complete image. If someone has a good sketch to start from I would be happy to get a link to the source-code to which I can add the web interface. Same for the baud rate (1920 are the alternatives). If this is not possible then the ESP-07S cannot be used because the system is frequently power cycled and the AP should stay at the same SSID/Passwrd all the time. Main issue for me is how to save and read back the modified data entered on the config webpage. But now the module is discontinued and I felt that rather than get into trouble with another supplier we should do it ourselves using readily available IoT WiFi modules. We already did this back in 2013 using a commercial WiFi module pre-programmed with the serial server etc.

PC:s and Android devices shall be able to talk to the instrument via TCP rather than RS232 with this adapter. This solution is in order to expose the serial connection for a data collection instrument onto a WiFi network interface.

Changes saved using a password protected button.

The configuration page shall contain the following configurable items:

Simple configuration web page on TCP port 80 (or maybe another more obscure port.).

Serial port server (completely transparent) on TCP port 2001, binary data in/out.

ESP-07S acting as a WiFi AP with protected login.

I need to design an application for the ESP8266 (the ESP-07S module) in order to deliver the following functions:

This is my first post on this forum, I just joined, so please excuse me if the questions are already answered! I have tried googling a lot and spent a few complete days worth of reading for this project, but now I need somewhere to ask too.
