v1.20

• The workflow is changed: instead of selecting a prebuilt firmware and hacking right on device's files, initial setup window now allows to select apps which have prebuilt binaries, and when the setup is done, the app's page is opened, where users can edit it, rebuild, and flash.
• External git binary is not required anymore for the mos tool to work.
• Packages available for Ubuntu 17.10 as well

1.6

• Added examples

Beta4 "Junkie Bear", 2016-04-26

Main reason for this release is the Mongoose IoT rebranding. What you are looking at now and what used to be called Smart.js is now Mongoose IoT Firmware.

Changes that happened since Beta3:

• Quite a bit if work on TI CC3200
• JS APIs for TCP and UDP
• File API changes (readAll removed)
• GPIO API changes (notably setmode -> setMode)
• Improved TLS support - a CA bundle (ca.pem) with 10 of most popular roots is now included by default.

Beta3 "Fat Rabbit", 2016-03-24

What's new

Beta3 "Fat Rabbit" is mainly a bug-fix and continuous improvement release. We've been very busy, there are tons of improvements; existing users are encouraged to upgrade. Please also consider upgrading to the most recent FnC flasher tool (https://github.com/cesanta/fnc/releases/latest).

A few highlights:

New features, improvements

• MQTT support
• TLS works on ESP Smart.js
• CC3200 support has been resumed
• ESP8266: Switch to OSS SDK 1.5.2
• ESP8266, LWIP: Adaptive TCP retransmit; faster networking in the face of packet loss
• Most Smart.js library code is now "frozen", i.e. it lives on flash memory. This is a huge saving for some archs such as esp8266.
• Implemented setInterval, clearInterval, clearTimeout
• Symbolic names: Debug.OFF, Debug.OUT, Debug.ERR, ...
• Sys.reboot takes an optional exit code. Useful on "posix" platforms.
• More helpers to check for heap corruptions
• ESP8266: Coredump gdb server support Espressif V2 image format (used in OTA builds)
• Improvements to crash reporting when emulating instructions in memory mapping soft handler
• Add Sys.time function
• ESP8266: Handle 32-bit timer overflow
• ESP8266: Support 8Mbit flash
• CC3200: GPIO support, interrupts.

Backward incompatible changes

• rename http.port to http.listen_addr config var
• rename v7_mk_opt to v7_create_opt due to a bad rename in Beta2

Bug fixes

Smart.js

• ESP8266: Watchdog timer fix: timeout duration is not reset after each feed.
• Fixed hang caused by a GPIO interrupt happening while the device is writing to flash (e.g. OTA update)
• Fix memory leaks in setTimeout

V7 JavaScript VM

• Fixed JS closures leak
• Smaller function call frame
• Added bcode memory footprint metrics
• Many memory corruption fixes caused by missed GC roots in C code.

Using Cesanta Cloud

Cesanta runs a public cloud service at https://cloud.cesanta.com. To login, all you need is a github or G+ account.
Any other cloud service can be used to store data - please take a look at the Http or WebSocket API.

The Smart.js firmware comes with an implementation of our websocket based protocol that is designed to make your device easily accessible behind NATs and to support disconnected operation by managing the queuing of messages for you:

https://www.cesanta.com/developer/cloud

Write your own handlers on your device and make it respond to commands send by other devices or by software running on your servers and call other device or store data such as metrics on our cloud services:

clubby.oncmd('/v1/MyThing.PokeMySensor', function(cmd, done) {
  print('got command:', cmd.args.blah);

  GPIO.write(yourLEDPin, true);

  clubby.call('//api.cesanta.com', {
    cmd: '/v1/Metrics.Publish',
    args: {vars: [[{__name__: 'frobulator'}, readFrobulatorValue()]]}
   }, function(res) {
    GPIO.write(yourLEDPin, false);
    done('your response');
  });
});
