WT32-ETH01
It is necessary to create a system of two devices:
1. "System Server" that provides wifi settings for the system client via http, and has a web interface accessible: a text field for entering the network name and wifi password for clients, settings for own IP, mask, router IP.
The main network connection is through ethernet. wifi is not used.
Settings must be saved after rebooting the device after power disconnection.
2. "System Client" Must control a single-channel relay module according to the algorithm:
- There is a connection with the server => relay state off
- No connection with the server and no connected wifi users => relay on
- No connection with the server and there are connected wifi users => relay off
Polling the server every 10 seconds.
Criterion for lack of connection: no access to the server three out of three requests to the server.
Criterion for presence of connection: at least one successful out of the last three requests to the server.
The client must have accessible from the web interface: settings for own IP, mask, router IP.
The main network connection is through ethernet. wifi is used exclusively for monitoring connected devices via wifi.
Settings must be saved after rebooting the device.
According to the logic of the client system, I need the simplest solution for the client like:
if (ServerHTTP.available()) and clientWiFi.available() then RelayState = on -no more logic is needed from the client
There needs to be one procedure to check for server availability:
Check for server availability every 10 seconds through an interrupt
- if the last three checks show it is unavailable then ServerHTTP.available() = false
- if at least one check shows it is available then ServerHTTP.available() = true
There is no need to receive data from the server. Just presence.
The second procedure checks for at least one device connected via WiFi
- If there are connections clientWiFi.available() = true
- If there are no connections clientWiFi.available() = false
That's all.
Initial settings can be like
192.168.1.111
255.255.255.0
192.168.1.1
WIFI FOR DATA TRANSMISSION IS NOT USED
