CMM2ESP

Arduino code for ESP8266 connected to CMM2. It comunicates with CMM2 over serial port with default speed of 691200 baud. It knows these commands:

@dhelp

• gets short help

@datetime

• gets date and time in format yyyy-mm-dd hh:mm:ss

@ver

• gets version of this firmware

@mac

• gets MAC address of WiFi

@netinfo

• gets info about connection to AP in format SSID, BSSID, RSI, gateway IP, network mask, own IP
• needs to be connected

@scan

• scans WiFi networks and returns:
  • number of networks found (n)
  • for every network number (0...n-1), SSID, BSSID, RSI
  • doesn't need to be connected

@disconnect

• disconnects from current AP
• returns info Disconnected

@connect(SSID, password)

• connect to AP
• returns info Connected to SSID, BSSID, RSI

@tcp(server:port)

• connects to TCP server
• connection can be broken with +++ (3 following pluses)

@http(url|split)

• split is not mandatory, default split is 250 characters

• send HTTP GET request to server

• returns HTTPGET url|number of batches (n) and then n times split characters with answer

  SEND @httpget(scooterlabs.com/echo?ip)

  • HTTPGET http://scooterlabs.com/echo?ip|1, follows just 1 packet (used default split is 250 characters)
  • 1.2.3.4

  SEND @httpget(scooterlabs.com/echo?ip|3)

  • HTTPGET http://scooterlabs.com/echo?ip|3, follow 3 packets (split was set to 3 characters per batch)
  • 1.2
  • .3.
  • 4

Then is here few commands for Napoleon Commander and test @speedtest

• Just for speed measurement. Prepares random data and then send data length, packet length, number of packets, rest in last packet, you need to accept this data, on the end it sends 1 line with speed info and CRC8.
• Next expects number of bytes to receive followed with this exact amount, againg on the end returns spped into

Napoleon Commander command

• @NC_?, @NC_W, @NC_R, @NC_C, @NC_D, @NC_T, @NC_M, @NC_N and @NC_K. These commands are used for communication with NCudpServer.py
