SSDP protocol work outo the box with window Module is seen as "ESP Module" serial is Chip ID, and other information are espressif ones for ESP 01 Not sure if need to set module name in EEPROM to be configurable =>TBD
ESP8266
FW for ESP8266 used with 3D printer
##Description
Thanks to @disneysw for bringing this module idea
Thanks to @lkarlslund for suggestion about independant reset using GPIO2
Have a bridge configurable by web (implemented) and optionally by printer (not yet implemented)
Have a front end to know what is the wifi status (implemented) or know what is the print status (not yet implemented) - this part can be optional and removed by compilation directive if no need
Should be compatible with reprap printer (Marlin FW/Repetier FW)
##Hardware connection
--Use GPIO2 to ground to reset all settings in hard way - 2-6 sec after boot / not before!! Set GPIO2 to ground before boot change boot mode and go to special boot that do not reach FW. Currently boot take 10 sec - giving 8 seconds to connect GPIO2 to GND and do an hard recovery for settings
--Use GPIO0 to ground to be in update mode
--Use a switch to reset/disable module
For Davinci Board:
##Development
Currently using Arduino IDE 1.6.5 with the esp8266 module from board manager added from github.com/esp8266/Arduino
using relased version (http://arduino.esp8266.com/package_esp8266com_index.json)
and staging version (http://arduino.esp8266.com/staging/package_esp8266com_index.json)
Additionnaly:
--Use minimal css from http://getbootstrap.com/examples/theme/ if connected to internet, this is to get better UI and rendering according display device (link can be changed in FW), if not available ,CSS is ignored displaying basic HTML
##Flash the Module
*Tools:
--Use IDE to upload directly (latest version of board manager module generate one binary)
*Connection --Connect GPIO0 to ground to be in update mode
##Web configuration
*Wifi Mode : Access point / Client station
*IP Generation: DHCP/Static IP
*IP/MASK/GATEWAY for static data
*Baud Rate for serial (supported : 9600, 19200, 38400, 57600, 115200, 230400)
*web port and data port
##Default Configuration
Default Settings:
AP:ESP8266
PW:12345678
Authentification: WPA
Mode: g (n is not supported by AP, just by STA)
channel: 11
AP: visible
Sleep Mode: Modem
IP Mode: Static IP
IP: 192.168.0.1
Mask: 255.255.255.0
GW:192.168.0.1
Baud rate: 9600
Web port:80
Data port: 8888
Web Page refresh: 3 secondes
These are the UI when css is in cache or internet is available:
##Commands from/to serial(not yet implemented):
*from module to printer [Need Printer FW support and can be disabled in ESP FW]
-M800 S1 , restart module done need a wifi/activity restart
-M801 [Message], Error message from module
-M802 [Message], Status message from module
-M804 [AP/STATION,SSID,DHC/STATIC,IP,MASK,GW,STATUS,MAC ADDRESSS, BAUD?], ]Module configuration without password
*from host to printer (not yet implemented) [Need Printer FW support] on port 8888
-M803 [IP, AP,SSID, Password....], ]Module configuration settings to be used by module
-M805 query to get M804 informations
*from printer to module [Need Printer FW support and can be disabled in ESP FW] (not yet implemented)
-request configuration/status (generate the M804 as answer)
-set AP/STATION,SSID,PASSSWORD,DHC/STATIC,IP,MASK,GW,BAUD from serial
##Front End (basic implemented) [need Printer FW support it] or just display module status
--Display printer status
--Display temperatures (done)
--Display positions/flow/speed (done)
--Display print progress if any
--List SDCard Content
--Launch/Stop/(Pause?) a Print
##TODO
-- Define Front End Functions
-- do testing
-- do a complete drawing for connections
-- add some Javascript to enhance web UI
