dnc40085 73773fd8a5 Update to the wifi module (#1497)
* Removed inline documentation for several functions and update comments
Since documentation is now part of the repository, the inline
documentation just adds to the already huge wifi.c

* Wifi module: add new functionality, update documentation

Functions Added:
wifi.getdefaultmode(): returns default wifi opmode
wifi.sta.apchange(): select alternate cached AP
wifi.sta.apinfo(): get cached AP list 
wifi.sta.aplimit(): set cached AP limit
wifi.sta.getapindex(): get index of currently configured AP
wifi.sta.getdefaultconfig(): get default station configuration
wifi.ap.getdefaultconfig(): get default AP configuration

functions modified:
wifi.setmode: saving mode to flash is now optional
wifi.sta.config: now accepts table as an argument and save config to
flash is now optional
wifi.sta.getconfig: added option to return table
wifi.ap.config: save config to flash is now optional
wifi.ap.getconfig: added option to return table

Documentation changes:
- Modified documentation to reflect above changes
- Removed unnecessary inline documentation from `wifi.c` 
- Updated documentation for `wifi.sta.disconnect`to address issue #1480 
- Fixed inaccurate documentation for function `wifi.sleeptype`
- Added more details to `wifi.nullmodesleep()`

* Move function `wifi.sleeptype()` to `wifi.sta.sleeptype()`

* Fixed problem where wifi.x.getconfig() returned invalid strings when
ssid or password were set to maximum length.

* fix error in documentation for `wifi.sta.getapindex`

* Renamed some wifi functions
wifi.sta.apinfo -> getapinfo
wifi.sta.aplimit -> setaplimit 
wifi.sta.apchange -> changeap

also organized the wifi_station_map array

Johny Mattsson 30d354c290 Rework ADC mode setting approach (#1285)
- Stop fighting against the SDK in terms of owning/writing the init_data block.
  NodeMCU included a default init_data block because originally the SDK did
  not, but by now it's not needed.

- Expose a way to reconfigure the ADC mode from Lua land. With most people
  using the cloud builder and not able to change the #define for byte 107
  this has been a pain point.

- Less confusion about which init_data has been used. Lua code can now simply
  state what mode it wants the ADC to be in, and not worry about the rest of
  the init_data complexities such as the init_data changing location due to
  flashing with wrong flash_size setting, or doing/not doing a chip-erase
  before loading new NodeMCU firmware.

2016-03-29 12:57:04 +11:00
Johny Mattsson e1fffe6ae4 Switch enduser_setup_module to LWIP raw API.
Shutting down an espconn server safely is impossible, and currently would
include at least one use-after-free. Even with that patched, at best this
would change things from impossible to "very tricky".

The native LWIP API does not have those issues, and is still quite easy
to work with.
2016-03-28 18:48:18 -04:00
Robert Foss 2d4f8f8e77 Improved overall enduser_setup user experience.
A single bug is fixed, a few features are added and overall the codebase has been worked through.

 - Added support for calls to /generate_204 that let's android know that the internet is accessible.
 - Added 10 second delay to the shutdown call to allow a final status update to be fetched by the client.
 - Added iframe to html to avoid having a form submission change the page.
 - Added support for dynamic /status responses.
 - Improved HTML appearance by removing AP-list button.
 - Improved CSS to center form, even when list of access points have loaded.
 - Improved debug prints to contain line numbers and not require lua_State*.
 - Fixed broken failure check when calling wifi_station_connect().
 - Fixed unguarded malloc().
