A simple network configuration utility for MicroPython on the ESP-8266 and ESP-32 boards
Project description
micropython-wifimanager
A simple network configuration utility for MicroPython on boards such as ESP8266 and ESP32.
Configuration
Simply upload your JSON file with your networks, the default path is '/networks.json', which is specified in the class property config_file
.
A sample configuration may look like this:
{
"schema": 2,
"known_networks": [
{
"ssid": "User\u2019s iPhone",
"password": "Password1",
"enables_webrepl": false
},
{
"ssid": "HomeNetwork",
"password": "Password2",
"enables_webrepl": true
}
],
"access_point": {
"config": {
"essid": "Micropython-Dev",
"channel": 11,
"hidden": false,
"password": "P@55W0rd"
},
"enables_webrepl": true,
"start_policy": "fallback"
}
}
Configuration schema
- schema: currently this should be
2
- known_networks: list of networks to connect to, in order of most preferred first
- SSID - the name of the access point
- password - the clear test password to use
- enables_webrepl - a boolean value to indicate if connection to this network desires webrepl being started
- access_point: the details for the access point (AP) of this device
- config - the keys for the AP config, exactly as per the micropython documentation
- enables_weprepl - a boolean value to indicate if ceating this network desires webrepl being started
- start_policy - A policy from the below list to indicate when to enable the AP
- 'always' - regardless of the connection to any base station, AP will be started
- 'fallback' - the AP will only be started if no network could be connected to
- 'never' - The AP will not be started under any condition
Simple usage (one shot)
Here's an example of how to use the WifiManager.
MicroPython v1.9.4 on 2018-05-11; ESP32 module with ESP32
Type "help()" for more information.
>>> from wifi_manager import WifiManager
>>> WifiManager.setup_network()
connecting to network Foo-Network...
WebREPL daemon started on ws://10.1.1.234:8266
Started webrepl in normal mode
True
Asynchronous usage (event loop)
The WifiManager can be run asynchronously, via the cooperative scheduling that micropthon has in uasyncio. If you call WifiManager.start_managing()
as follows, it will ensure that periodically the network status is scanned, and connection will be re-established as per preferences as needed.
import uasyncio as asyncio
from wifi_manager import WifiManager
WifiManager.start_managing()
asyncio.get_event_loop().run_forever()
