Function Documentation

shell_backend_mqtt_get_ptr()

const struct shell * shell_backend_mqtt_get_ptr

(

void

)

This function provides pointer to shell mqtt backend instance.

Function returns pointer to the shell mqtt instance. This instance can be next used with shell_execute_cmd function in order to test commands behavior.

Returns

Pointer to the shell instance.

shell_mqtt_get_devid()

bool shell_mqtt_get_devid	(	char *	id,
		int	id_max_len )

Function to define the device ID (devid) for which the shell mqtt backend uses as a client ID when it connects to the broker.

It will publish its output to devid_tx and subscribe to devid_rx for input .

Note

This is a weak-linked function, and can be overridden if desired.

Parameters

id	Pointer to the devid buffer
id_max_len	Maximum size of the devid buffer defined by DEVICE_ID_HEX_MAX_SIZE

Returns

true if length of devid > 0
