Fork of ESP8266Interface by ESP8266

This is an alternative implementation of the ESP8266 driver that uses the NodeMCU firmware. The NodeMCU firmware provides a slightly larger feature set than the default firmware through a Lua interpreter.

Interface changes

• SSID and passphrase moved out of ESP8266Interface constructor and to ESP8266Interface::connect
• ESP8266Interface constructor provides optional timeout parameter to specify how long to wait for network operations

Firmware

To install the NodeMCU firmware, follow the instructions on the Firmware Update wiki page using the nodemcu_integer_0.9.6-dev_20150406.bin binary at address 0x00000 instead of boot_v1.1.bin and user1.bin.

Since the NodeMCU firmware defaults to a baud rate of 9600, the Serial Passthrough program can be used to get direct access to the Lua interpreter running on the ESP8266.

Status

Working features:

• TCP Client
• UDP Client Transmit (Currently only UDP Server can recieve messages)
• Single Connection at a time
• Station Mode (Connects to AP)
• DNS Lookups

To be implemented:

• TCP Server
• UDP Server
• UDP Client recieve
• Multiple Connections tracked through Lua variables
• AP Mode (Act as access point)
• IPV6 support (Existing issue with NodeMCU)
