| − | To make the ESP8266 more accessible to everyone I have created a "programmer" which allows for easy firmware uploading and communication with the module.

| − | == loading scripts from a webserver ==
| |
| − | | |
| − | I ([[User:Da Syntax|Da Syntax]]) got tired from typing the scripts line for line into the lua console of the nodeMCU firmware. I wrote a little function to load the scripts from a webserver running on my laptop. This way I can just save the script on my laptop and load it to my ESP8266 calling 2 functions ( netload() and dofile("netloaded.lua") )
| |
| − | <pre>function netload()
| |
| − | conn=net.createConnection(net.TCP, 0)
| |
| − | conn:on("receive", function(conn, payload)
| |
| − | print(payload)
| |
| − | file.open("netloaded.lua", "w")
| |
| − | file.write(payload)
| |
| − | file.close()
| |
| − | end)
| |
| − | conn:connect(8080,"192.168.1.193")
| |
| − | conn:send("GET /test.lua HTTP/1.1\r\nHost: www.example.com\r\n" .."Connection: keep-alive\r\nAccept: */*\r\n\r\n")
| |
| − | end
| |

| |
| − | Future plans
| |
| − | | |
| − | *Send mac address of the wifi module in get so the web server can return device specific firmwares
| |
| − | *Put the script between specific tags so there won't be any problems with headers that are added by the web server + gives the possibility to add meta data (e.g. version of script or a signature)
| |
| − | *Create a nice php/mysql webapp to easily manage the scripts per module
