 /** mDot_TTN_DS18B20 - Simple mDot temperature sensor using Dallas Semiconductors DS18B20 OneWire temperature sensor.
- * It used the OTA_AUTO join mode using saved parameters. If the config is to be reset then pin A2 on the
- * dev board must be held low during a reset or power up.
+ * It used the MANUAL join mode with parameters for The Things Network.
+ * 
  *
  * Uses MultiTech mDot developer board http://www.multitech.com/models/94558010LF
  * Requires a MultiTech MultiConnect Conduit http://www.multitech.com/models/94557203LF
