micropython-cloudmanager 0.0.142

Micropython client that allows network attached boards to be controlled from a central redis server

Description

Cloudmanger provides a single point of managment for micropython systems that minimizes the security attack surface and offloads resource intensive operations from the micropython clients to the server.

Quickstart

Here is a quickstart for setting up cloudmanager with popular esp8266 boards

Install

Use pip to install the server and client flash utility:

$ pip install micropython-cloudmanager micropython-cloudmanager-esp8266
$

Start Server

Start the server process with the default settings:

$ mbm server-start
Cloudmanager service is listening on: 192.168.1.127:18266
$

Flash and Configure esp8266 board as a client

Plug in the esp8266 board, into the usb port.

NOTE: Some boards may need to be manually put into flash mode per the vendor instructions.

The flash tool will generally determine the correct serial device to flash as long as only one usb serial device is connected to the system.

Flash and configure the board specifying the wifi connection settings:

$ flash_esp_image --wifi_ssid mywifi --wifi_password mywifipassword
esptool.py --port /dev/ttyUSB0 --baud 115200 erase_flash

>>> from bootconfig.config import get, set

>>> set('redis_server', '192.168.1.127')
>>> import bootconfig.service
>>> bootconfig.service.autostart()
>>> import redis_cloudclient.service
>>> redis_cloudclient.service.autostart()
>>> import machine
>>> machine.reset()

NOTE: At this point some boards need to be manually reset.

Verify the board is registered with the server

After a few seconds the board should connect to the wifi network and register with the cloudmanager server:

$ mbm board-list
Name       Platform                                           State
esp8266-1  esp8266                                            idle
$

See the full documentation to use cloudmanager to install packages, upload files or execute commands on the board.
