◆ rn2xx3_setup()

void rn2xx3_setup	(	rn2xx3_t *	dev,
		const rn2xx3_params_t *	params
	)

Prepares the given RN2XX3 device.

Parameters

[in]	params	parameters for device initialization

◆ rn2xx3_sys_factory_reset()

int rn2xx3_sys_factory_reset ( rn2xx3_t * dev )

Performs a factory reset of the module.

The configuration data and user EEPPROM are reinitialized to factory default values and the module reboots

After calling this function, dev->resp_buf contains the module name and version string.

Parameters

[in] dev RN2XX3 device descriptor

Returns: RN2XX3_OK on success; RN2XX3_TIMEOUT if UART communication failed

◆ rn2xx3_sys_reset()

int rn2xx3_sys_reset ( rn2xx3_t * dev )

Restarts the RN2XX2 device.

After calling this function, dev->resp_buf contains the module name and version string.

Parameters

[in] dev RN2XX3 device descriptor

Returns: RN2XX3_OK on success; RN2XX3_TIMEOUT if UART communication failed

◆ rn2xx3_sys_set_sleep_duration()

void rn2xx3_sys_set_sleep_duration	(	rn2xx3_t *	dev,
		uint32_t	sleep
	)

Sets the rn2xx3 sleep mode duration (in ms)

Parameters

[in]	dev	The rn2xx3 device descriptor
[in]	sleep	The sleep mode duration (ms)

◆ rn2xx3_sys_sleep()

int rn2xx3_sys_sleep ( rn2xx3_t * dev )

Puts the RN2XX2 device in sleep mode.

Parameters

[in] dev RN2XX3 device descriptor

Returns: RN2XX3_OK on success; RN2XX3_TIMEOUT if UART communication failed

◆ rn2xx3_wait_reply()

int rn2xx3_wait_reply	(	rn2xx3_t *	dev,
		uint8_t	timeout
	)

Waits for a reply from the LoRaWAN network.

Parameters

[in]	dev	LoRaBee device descriptor
[in]	timeout	Reply wait timeout in seconds

Returns: RN2XX3_REPLY_TIMEOUT when no MAC reply is received from server; RN2XX3_REPLY_TX_MAC_OK when MAC transmission succeeded; RN2XX3_REPLY_TX_MAC_ERR when MAC transmission failed; RN2XX3_REPLY_TX_MAC_RX when received downlink data from server; RN2XX3_REPLY_TX_INVALID_DATA_LEN when Application payload is too large; RN2XX3_REPLY_JOIN_ACCEPTED when the join procedure succeeded; RN2XX3_REPLY_JOIN_DENIED when the join procedure failed; RN2XX3_REPLY_OTHER when an unknown reply is received

◆ rn2xx3_wait_response()

int rn2xx3_wait_response ( rn2xx3_t * dev )

Waits for a response to a command from the device.

Parameters

[in] dev RN2XX3 device descriptor

Returns: RN2XX3_OK on success; RN2XX3_TIMEOUT if no response is received from the module; RN2XX3_ERR_INVALID_PARAM if command is invalid; RN2XX3_ERR_NOT_JOINED if network is not joined; RN2XX3_ERR_NO_FREE_CH if no free channel; RN2XX3_ERR_SILENT if device is in Silent state; RN2XX3_ERR_FR_CNT_REJOIN_NEEDED if frame counter rolled over; RN2XX3_ERR_BUSY if MAC is not in Idle state; RN2XX3_ERR_INVALID_DATA_LENGTH if payload is too large; RN2XX3_ERR_KEYS_NOT_INIT if keys are not configured

◆ rn2xx3_write_cmd()

int rn2xx3_write_cmd ( rn2xx3_t * dev )

Writes a command to the RN2XX3 device.

The module will immediately reply with a meaningful message if the command is valid or not.

Parameters

[in] dev RN2XX3 device descriptor

Returns: RN2XX3_OK on success; RN2XX3_TIMEOUT if no response is received from the module; RN2XX3_ERR_INVALID_PARAM if command is invalid; RN2XX3_ERR_NOT_JOINED if network is not joined; RN2XX3_ERR_NO_FREE_CH if no free channel; RN2XX3_ERR_SILENT if device is in Silent state; RN2XX3_ERR_FR_CNT_REJOIN_NEEDED if frame counter rolled over; RN2XX3_ERR_BUSY if MAC is not in Idle state; RN2XX3_ERR_INVALID_DATA_LENGTH if payload is too large; RN2XX3_ERR_KEYS_NOT_INIT if keys are not configured

◆ rn2xx3_write_cmd_no_wait()

int rn2xx3_write_cmd_no_wait ( rn2xx3_t * dev )

Writes a command to the RN2XX3 device but don't wait for timeout or response.

The response can be checked in the dev->resp_buf buffer after a small delay (for example 1ms).

Parameters

[in] dev RN2XX3 device descriptor

Returns: RN2XX3_OK on success
