CORDOVA-ET v0.4.3

New version with several improvements:

• Soil temperature sensor stability
• Updated Downlink commands for setting up WiFi, force LoRaWAN and reset config
• Added new commands to the terminal: join LoRaWAN, print config, etc
• Compatibility with Telnet for wireless setup

Telnet compatibility

This version support configuration over WiFi using Telnet. Just connect to the WiFi CET-XXXX and launch telnet 192.168.4.1. User is uco and password ias_csic. You can interact with the serial port.

Important

Make sure to change the WiFi password in the config.py. If you are using different WiFi settings, you can change them here too.

If running 0.4.0 or 0.4.1 you can perform an OTA with the 'o' command. Just make sure you are close to the 4G Router. The OTA server is not always running. If you plan to perform an upgrade using OTA, contact the UCO team.

Known issues

At the moment, there is a timeout on the Setup console. If no key is pressed, the board resets after 30 seconds.

CORDOVA-ET v0.4.1

Official version for CORDOVA-ET Nodes. This matches OTA v1.0.1.
This version supports new hardware boards:

• v3.x with SD card storage and updated pinouts

• Pyranometer nodes

LoRaWAN keys are automatically generated from the internal MAC and Sigfox ID.
To allow for OTA updates, ensure that the config.py parameters for the Wifi are correct.
