This is a nice idea i can connect multiple clients to one server as i am new to this and never did ESP8266 programming can you please help me out in setting one of these projects
To go arduino ide programming route, Perhaps look at this lib to read the rfid h/w
and for connecting to a wifi network to publish a Mqtt Topic/payload message perhaps this lib will provide you with the code snippets and explaination needed.. https://github.com/256dpi/arduino-mqtt
If the arduino and its ide are new to you? youtube has lots of great tutorials and its a system designed for kids to learn so there are LOTS of online resources and help..
I would start with getting the example sketch for the rfid h/w talking to the h/w, and then add in the code from the mqtt example to connect to the wifi and publish the reading...
To use tasmota or another firmware project flash and configure, though rfid h/w support is limited, you may be able to simply publish the raw output from a connected spi device? but thats beyond my own experience with the f/w
iirc the feature to output raw sensor data is the 'serial bridge'
The precompiled firmware solution may involve a little more reading but should be the fastest route..
would there be any mistake in communication if it is send from reader 1 the signal goes to reader 2 would there be any problems like this
Read up on mqtt and consider how you format the topics and payloads you publish as a good design will eliminate such concerns perhaps publish using a topic like "RFID/ESP-001/" with a payload of raw data or a decoded state.
anyways it would be great help from you guys to simply set up
all i want to convert is the link for code i provided is to be in client and server state so server side is to send a signal after receiving the rfid UID and want the Esp8266 to send data of UID to raspberry pi and authenticate
help would be very needful in this project
You wont find folk to 'do your homework' for you in here but will find lots of help if you hit a stumbling block while working it out for yourself or need a pointer..
