Test Requirements

• Low-temperature storage test:

Place the DUT in the temperature chamber and set the low temperature to -10˚ C. The DUT can power up and login via SSH when all temperature monitoring points reach -10˚ C.

• Low-temperature work test:

a. When all test points reach -10˚ C, The DUT can power up and login via SSH.

b. It can connect to the cloud server to send and receive LoRa packets.

c. The LAN port and Wi-Fi work well.

• High-temperature storage test:

Place the DUT in the temperature chamber and set the high temperature to 65˚ C. The DUT can power up and login via SSH when all temperature monitoring points reach 65˚ C.

• High-temperature work test:

a. When all test points reach 65˚ C, The DUT can power up and login via SSH.

b. It can connect to the cloud server to send and receive LoRa packets.

c. The LAN port and Wi-Fi work well.
