This is the quick start guide for the LoRaWAN Driver using RN2384 Module, with step-by-step instructions on how to configure and use the driver in a selection of use cases.

The use cases contain several code fragments. The code fragments in the steps for setup can be copied into a custom initialization function, while the steps for usage can be copied into, e.g., the main application function.

LoRa Driver use cases

Initialise the driver

The following must be added to the project:

#include <lora_driver.h>

Add to application initialization:

Initialise the driver without down-link possibility:
lora_driver_initialise(ser_USART1, NULL); // The parameter is the USART port the RN2483 module is connected to - in this case USART1 - here no message buffer for down-link messages are defined
Alternatively initialise the driver with down-link possibility:
MessageBufferHandle_t downLinkMessageBufferHandle = xMessageBufferCreate(sizeof(lora_driver_payload_t)*2); // Here I make room for two downlink messages in the message buffer

lora_driver_initialise(ser_USART1, downLinkMessageBufferHandle); // The parameter is the USART port the RN2483 module is connected to - in this case USART1 - here no message buffer for down-link messages are defined

Then the LoRaWAN transceiver needs to be hardware reset.

Note: This must be done from a FreeRTOS task!!
lora_driver_resetRn2483(1); // Activate reset line

vTaskDelay(2);

lora_driver_resetRn2483(0); // Release reset line

vTaskDelay(150); // Wait for tranceiver module to wake up after reset

lora_driver_flushBuffers(); // get rid of first version string from module after reset!

Now you are ready to use the LoRaWAN module :)
