i would add xpl protocol plugin on esp8266 easy
i would create an new udp socket with CPLUGIN_PROTOCOL_ADD function , and add in checkUDP function the check off incoming xpl message. for sending message periodically i would use "CPLUGIN_PROTOCOL_SEND" function .
the xpl library used is https://github.com/olebrun/xPL.Arduino
the memory footprint is very small
do you have any recommendations (architecture, using API, etc ...) ?
excuse me for writing mistakes
