[LoRa] set deep sleep interval by downlink message

[thiasB]

Introduction

The datalogger can now process two kinds of LoRaWAN downlink messages.

1. Change deep sleep interval in minutes (via port 1).
2. Pause transmission of sensor data, e.g. when working on the bees (via port 2). In this mode, an almost empty payload is sent. What is now always transmitted in digital_output_1 is this status: "pause" or "active".
   • Since keys for both commands are saved to NVRAM they remain valid after power cycle, reset and deep sleep.
   • keep in mind that the changes take effect after the next uplink with a successful downlink transmission to the device

Operation

Deep sleep interval

• Send value via LoraWAN port 1 as minutes in hex.
• values from 1 to 255 minutes allowed
• Sending 0x00 resets the NVRAM key and returns to the "field" interval in settings.py.

Pause sensor data

• via LoraWAN port 2 as hex values
• 0x00 -> normal sensor data submission
• 0x01 -> pause submissions

Telegram bot

• a Telegram bot that conveniently submits those "pause" vs. "active" messages will be contributed soon.
• by now the bot works per device
• commands available:
  • /sleep [MIN] (without an argument the device will return to default sleep interval)
  • /pause
  • /unpause
