|
The current version of this module exploits the stdin / stdout pipe functionality and
|
||
|
|
task integration that is now build into the NodeNMCU Lua core.
|
||
|
|
|
||
|
|
There are two nice advantages of this core implementation:
|
||
|
|
|
||
|
|
- Errors are now written to stdout in a separate task execution.
|
||
|
|
- The pipes pretty much eliminate UART and telnet overrun.
|
||
|
|
|
||
|
|
Both have the same interface if required into the variable `telnet`
|
||
|
|
|
||
|
|
## telnet:open()
|
||
|
|
|
||
|
|
Open a telnet server based on the provided parameters.
|
||
|
|
|
||
|
|

|
|
|

`telnet:open(ssid, pwd, port)`

|
|
|
||
|
|
#### Parameters
|
||
|
|
|
||
|
|
`ssid` and `password`. Strings. SSID and Password for the Wifi network. If these are
|
||
|
|
`nil` then the wifi is assumed to be configured or auto-configured.
|
||

## telnet:close()
|

|
|
