This example shows how to configure the LoRaWAN parameters of the module by calling the API, including region, class, join_mode, dr, etc.
The example is developed on the basis of standard firmware, and the added code is in the comment range of /* User Code */, /* End User Code */.
The key function in the example is setup(), which is called during initialization. LoRaWAN parameters are set in the function, and these parameters are described below:
1. LoRa Work Mode
Set LoRa working mode.
Modes: LoRaWAN, LoRa P2P
In the example, we set it to LoRaWAN
rui_lora_set_work_mode()
2. Region
Set the Region.
Supported Regions: AS923, AU915, CN470, EU433, EU868, KR920, IN865, US915.
rui_lora_set_region()
3. Join Mode
Set LoRaWAN Join mode.
Modes: OTAA, ABP
The example always defaults to the OTAA mode, and you can comment the ʻUSER_LORAWAN_OTAA` macro definition to switch to the ABP mode.
OTAA mode needs to set dev_eui, app_eui, app_key. ABP mode needs to set dev_addr, apps_key, nwks_key.
rui_lora_set_dev_eui(), rui_lora_set_app_eui(), rui_lora_set_app_key()
rui_lora_set_dev_addr(), rui_lora_set_apps_key(), rui_lora_set_nwks_key()
4. Class
Set LoRaWAN Class.
Classes: ClassA, ClassC
The example is set to ClassA.
rui_lora_set_class()
5. Packet Type
Set the data packet type: Confirmed packet and Unconfirmed Packet.
The example is set to unconfirmed package.
rui_lora_set_confirm()
6. Data Rate
Set the data rate.
The data rate range is different in different regions, please refer to the LoRaWAN Regional Parameters v1.0.2 document according to your region.
rui_lora_set_dr()
7. Transmission (TX) Power
Set the transmission power.
The transmit power range in different regions is different, please refer to the LoRaWAN Regional Parameters v1.0.2 document.
rui_lora_set_tx_power()
8. Adaptive Data Rate (ADR)
Enable/disable adaptive data rate.
Set to disable in the example.
rui_lora_set_adr()
