assume a building floor 120sqr yards and has 4 rooms so i want to mange all the inventories in it. i want to place some kind of tags and use a reader to detect them i hope u understand.

so there for i use ESP8266
can anybody further help me how to get the location.
Suppose 2 rooms have 2 different router. a inventory have ESP8266 in it. and connected to router. but how should i detect that the inventory in room 1 has been shifted to room 2.


can anybody know how to extract the mac address from the router and place into the the data base..

- Thu Mar 24, 2016 8:37 pm #43982 do you really have to do it wiith a mac address?

you can also try to set room1 router's ip to ie. 192.168.1.1, the other to ie. 192.168.2.1.

if esp ip is 192.168.1.x, it is connected to room1 router.

question:
how do you plan to power the esp while in the inventory?

Of course, otherwise it won't work.
In fact, each ESPs have 2 MAC, one for AP and one for STA.
