netid

This API allows the user to access the network identifier (NetID).

RAKLorawan::netid

get()

This API allows the user to get the network identifier (NetID).

api.lorawan.netid.get(buf, len);

Function	bool get(uint8_t* buf, uint32_t len)
Parameters	buf: the buffer to get the network identifier (NetID) len: the length of the network identifier (NetID) (must be 3 bytes)

NOTE

This is an asynchronous command. A result of TRUE means that the device is joining. The completion of the join process can be verified with the api.lorawan.njs.get() command.

Parameters of api.lorawan.join() command are optional. You can use api.lorawan.join() directly to join the LoRaWAN network. If no parameters are configured, the device will use the default values.

The result of the join process is reported in the JoinCallback. You can register a join callback handler with api.lorawan.registerJoinCallback(service_lora_join_cb callback)

This API provides the way to P2P send data.

NOTE

• P2P TX mode can be blocked by certain settings in P2P RX mode. To ensure that P2P RX mode is not blocking the psend() API, you can disable P2P RX mode and switch to P2P TX mode via api.lora.precv(0).
• By default, CAD is disabled. When CAD mode is enabled, the device will continue to check for channel activity until it can send the packet.

api.lora.psend(length, payload, ena_cad);

Function	bool psend(uint8_t length, uint8_t * payload, bool ena_cad)
Parameters	length - the length of the payload payload - the data send to the other device ena_cad - enable (TRUE) or disable (FALSE) CAD before sending
Returns	bool
Return Values	TRUE for sending data success FALSE for sending data failure

precv()

This API is used to enter P2P RX mode for a specified period.

api.lora.precv(uint32_t timeout)

Function	bool precv(uint32_t timeout)
Parameters	timeout - the duration of P2P Rx mode in milliseconds Special timeout values: 65535: Stay in RX mode until a packet is received. 65534: Permanent RX mode (TX not possible) until api.lora.precv(0) is executed. 65533: Permanent RX mode and still allows TX without calling api.lora.precv(0).
Returns	bool
Return Values	TRUE for entering P2P Rx mode success FALSE for failure to activate P2P RX mode
