Note:
1. Make sure the device is set to ABP mode in the IoT Server.
2. Make sure the LG01/02 gateway RX frequency is exactly the same as AT+CHS setting.
3. Make sure SF / bandwidth setting in LG01/LG02 match the settings of AT+DR. refer this link to see what DR
means.
4. The command AT+RX2FQ and AT+RX2DR is to let downlink work. to set the correct parameters, user can
check the actually downlink parameters to be used. As below. Which shows the RX2FQ should use 868400000 and
RX2DR should be 5
