199 -The DMT01 is configured as (% style="color:#037691" %)**LoRaWAN OTAA Class A**(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the DMT01. It will automatically join the network via OTAA and start to send the sensor value.

465 +==== (% style="color:#4472c4" %)**Food temperature**(%%) ====
466 +
467 +Because the food temperature data is a little-endian sequence, the order of the front and back bytes needs to be swapped during decoding.

469 +**Example**:
470 +
471 +If payload is: D300H = 00D3H, temp = 00D3H /10 = 21.1 degree
