LoRaWAN class types.
Enumerator | |
---|---|
LORAWAN_CLASS_A | Class A device. |
LORAWAN_CLASS_B | Class B device. |

enum lorawan_datarate |
#include <zephyr/lorawan/lorawan.h>
LoRaWAN datarate types.
enum lorawan_message_type |
#include <zephyr/lorawan/lorawan.h>
LoRaWAN message types.
Enumerator | |
---|---|
LORAWAN_MSG_UNCONFIRMED | Unconfirmed message. |

enum lorawan_region |
#include <zephyr/lorawan/lorawan.h>
LoRaWAN region types.
void lorawan_enable_adr | ( | bool | enable | ) |
#include <zephyr/lorawan/lorawan.h>
Enable Adaptive Data Rate (ADR)
Control whether adaptive data rate (ADR) is enabled. When ADR is enabled, the data rate is treated as a default data rate that will be used if the ADR algorithm has not established a data rate. ADR should normally only be enabled for devices with stable RF conditions (i.e., devices in a mostly static location).
enable | Enable or Disable adaptive data rate. |
enum lorawan_datarate lorawan_get_min_datarate | ( | void | ) |
#include <zephyr/lorawan/lorawan.h>
Get the minimum possible datarate.
The minimum possible datarate may change in response to a TxParamSetupReq command from the network server.
#include <zephyr/lorawan/lorawan.h>
Get the current payload sizes.
Query the current payload sizes. The maximum payload size varies with datarate, while the current payload size can be less due to MAC layer commands which are inserted into uplink packets.
max_next_payload_size | Maximum payload size for the next transmission |
max_payload_size | Maximum payload size for this datarate |
int lorawan_join | ( | const struct lorawan_join_config * | config | ) |

Join the LoRaWAN network.
Join the LoRaWAN network using OTAA or AWB.

void lorawan_register_battery_level_callback | ( | lorawan_battery_level_cb_t | cb | ) |
#include <zephyr/lorawan/lorawan.h>
Register a battery level callback function.
Provide the LoRaWAN stack with a function to be called whenever a battery level needs to be read.
Should no callback be provided the lorawan backend will report 255.
cb | Pointer to the battery level function |
void lorawan_register_downlink_callback | ( | struct lorawan_downlink_cb * | cb | ) |
#include <zephyr/lorawan/lorawan.h>
Register a callback to be run on downlink packets.

void lorawan_register_dr_changed_callback | ( | lorawan_dr_changed_cb_t | cb | ) |
#include <zephyr/lorawan/lorawan.h>
Register a callback to be called when the datarate changes.
The callback is called once upon successfully joining a network and again each time the datarate changes due to ADR.
cb | Pointer to datarate update callback |

Send data to the connected LoRaWAN network.
port | Port to be used for sending data. Must be set if the payload is not empty. |
data | Data buffer to be sent |

type | Specifies if the message shall be confirmed or unconfirmed. Must be one of lorawan_message_type. |
#include <zephyr/lorawan/lorawan.h>
Set the channels mask.
Change the default channels mask. When mask is not changed, all the channels can be used for data transmission. Some Network Servers don't use all the channels, in this case, the channels mask must be provided.
channels_mask | Buffer with channels mask to be used. |
channels_mask_size | Size of channels mask buffer. |
0 | successful |
-EINVAL | channels mask or channels mask size is wrong |
int lorawan_set_class | ( | enum lorawan_class | dev_class | ) |
#include <zephyr/lorawan/lorawan.h>
Set the current device class.
Change the current device class. This function may be called before or after a network connection has been established.
dev_class | New device class |
int lorawan_set_conf_msg_tries | ( | uint8_t | tries | ) |

int lorawan_set_region | ( | enum lorawan_region | region | ) |
#include <zephyr/lorawan/lorawan.h>
Set the region and frequency to be used.
Control the LoRa region and frequency settings. This should be called before lorawan_start(). If you only have support for a single region selected via Kconfig, this function does not need to be called at all.
region | The region to be selected |
int lorawan_start | ( | void | ) |
#include <zephyr/lorawan/lorawan.h>
Start the LoRaWAN stack.
This function need to be called before joining the network.
