Detailed Description

The Settings library provides access to node settings, which are stored in nonvolatile memory. When a node starts up it automatically uses these stored settings.

Settings such as node role, unique node address, network address and channel, encryption and authentication keys as well performance-related settings such as access cycle limits can be stored and recalled. Also see the State library state.h for starting and stopping the stack.

Library services are accessed via lib_settings handle.

◆ app_lib_settings_is_group_cb_f

typedef bool(* app_lib_settings_is_group_cb_f) (app_addr_t group_addr)

Callback used for determining on which multicast groups the device belongs.

As an argument, the stack sets the address of the multicast group. If device belongs to that group, callback function returns true. If not, callback returns false.

This callback is called when device receives multicast packet. The return value is then determined whether data shall be received by standard means (i.e. data reception callback, see lib_data->setDataReceivedCb)

Parameters

group_addr Group address (with APP_ADDR_MULTICAST bitmask set)

Returns: true: is in multicast group, false: is not in multicast group

◆ app_lib_settings_set_ac_range_f

typedef app_res_e(* app_lib_settings_set_ac_range_f) (uint16_t ac_min_value, uint16_t ac_max_value)

Set range for access cycle.

Set the access cycle range that this node uses to serve its neighbors. This setting is only meaningful for nodes that route data for others, i.e. sinks and headnodes.

Normally the stack chooses a suitable access cycle automatically, between 2, 4 or 8 seconds, depending on the amount of network traffic. Some applications may need to further limit the access cycle durations in use.

The values are in milliseconds. Function lib_settings->getAcRangeLimits() can also be used to query the limits. Default range is min. 2000 ms, max. 8000 ms.

Valid values are:

Value	Description
2000	2 seconds
4000	4 seconds
8000	8 seconds

If value is not set, or maximum > minimum, the stack chooses an appropriate access cycle based on the amount of network traffic. If maximum = minimum, the user can force the access cycle to a specific duration. Range is not set by default. Only a factory reset can restore range back to the unset state.

Example:

lib_settings->setAcRange(2000, 2000); // Fix access cycle to 2s

Parameters

ac_min_value	Minimum access cycle value to set
ac_max_value	Maximum access cycle value to set

Returns: Result code, APP_RES_OK if successful, APP_RES_INVALID_VALUE if ac_min_value or ac_max_value is invalid

Note: This setting is not possible when device role has flag APP_LIB_SETTINGS_ROLE_FLAG_LL mode set. Instead, those devices always have automatic access cycle selection enabled.

◆ app_lib_settings_set_authentication_key_f

typedef app_res_e(* app_lib_settings_set_authentication_key_f) (const uint8_t *key_p)

Set authentication key.

key_p must point to APP_LIB_SETTINGS_AES_KEY_NUM_BYTES bytes. By default, no authentication key is set.

A key of all 0xff (hex) bytes is considered an unset key. Setting such a key disables encryption and authentication.

Parameters

key_p Pointer to AES-128 key, APP_LIB_SETTINGS_AES_KEY_NUM_BYTES bytes

Returns: Result code, APP_RES_OK if successful, APP_RES_INVALID_STACK_STATE if stack is running, APP_RES_INVALID_NULL_POINTER if key_p is NULL

Note: Note that both the encryption and authentication keys must be set for the encryption or authentication to be enabled. It is NOT enough to set just one key.

Definition at line 366 of file wms_settings.h.

◆ app_lib_settings_set_encryption_key_f

typedef app_res_e(* app_lib_settings_set_encryption_key_f) (const uint8_t *key_p)

Set encryption key.

key_p must point to APP_LIB_SETTINGS_AES_KEY_NUM_BYTES bytes. By default, no encryption key is set.

A key of all 0xff (hex) bytes is considered an unset key. Setting such a key disables encryption and authentication.

Parameters

key_p Pointer to AES-128 key, APP_LIB_SETTINGS_AES_KEY_NUM_BYTES bytes

Returns: Result code, APP_RES_OK if successful, APP_RES_INVALID_STACK_STATE if stack is running, APP_RES_INVALID_NULL_POINTER if key_p is NULL

Note: Note that both the encryption and authentication keys must be set for the encryption or authentication to be enabled. It is NOT enough to set just one key.

Definition at line 404 of file wms_settings.h.

◆ app_lib_settings_set_feature_lock_bits_f

typedef app_res_e(* app_lib_settings_set_feature_lock_bits_f) (uint32_t bits)

Set feature lock bits.

See lib_settings->getFeatureLockBits() for a description of feature lock bits. A cleared bit marks a feature locked. Reserved bits must remain set.

Parameters

bits	Feature lock bits

Returns: Result code, APP_RES_OK if successful, APP_RES_INVALID_VALUE if an unsupported lock bit is set to 0

Definition at line 163 of file wms_settings.h.

◆ app_lib_settings_set_feature_lock_key_f

typedef app_res_e(* app_lib_settings_set_feature_lock_key_f) (const uint8_t *key_p)

Set feature lock key.

Lock or unlock the feature lock. key_p must point to APP_LIB_SETTINGS_AES_KEY_NUM_BYTES bytes. The feature lock key is not an AES-128 key, but it is guaranteed to be the same size as an AES-128 key.

Feature lock key can only be set when the feature lock is unlocked. Unlocking is done by setting the key using the same key as when locking it. A key of all 0xff (hex) bytes is considered an unset key. Setting such a key does not lock the feature lock.

Parameters

key_p Pointer to key, APP_LIB_SETTINGS_AES_KEY_NUM_BYTES bytes

Returns: Result code, APP_RES_OK if successful, APP_RES_INVALID_VALUE if a key is set and trying to unlock with a wrong key, APP_RES_INVALID_NULL_POINTER if key_p is NULL

Definition at line 200 of file wms_settings.h.

◆ app_lib_settings_set_group_query_cb_f

typedef app_res_e(* app_lib_settings_set_group_query_cb_f) (app_lib_settings_is_group_cb_f cb)

Set the callback function for multicat groups.

The callback is called when stack needs to determine on which multicast groups the device belongs to. If callback is not defined, device does not belong to any multicast groups.

Parameters

cb	The function to be executed, or NULL to unset

Returns: Result code, always APP_RES_OK

Example on use:

// This device belongs to this group
#define OWN_GROUP (APP_ADDR_MULTICAST | 1)
 
bool group_query_cb(app_addr_t group_addr)
{
    return (group_addr == OWN_GROUP);
}
 
void App_init(const app_global_functions_t * functions)
{
    lib_settings->registerGroupQuery(group_query_cb);
    // ...
    lib_state->startStack();
}

◆ app_lib_settings_set_reserved_channels_f

typedef app_res_e(* app_lib_settings_set_reserved_channels_f) (const uint8_t *channels_p, size_t num_bytes)

Set reserved channels.

Mark channels as reserved, or to be avoided by the Wirepas Mesh protocol. Each set bit marks a channel that is to be avoided. The LSB of the first byte is channel 1, the LSB of the next byte is channel 8 and so forth. The channels_p bit array may be shorter than the number of channels. In that case, the remaining channels are marked as not reserved. The bit array may be longer too, provided that the highest bit set in it corresponds to a valid channel number (see section 3.6.4.27), i.e. extra zeros are ignored.

A node may still transmit on a reserved channel if it has a neighbor that has not been configured to avoid the channel. For best results, all nodes in a network should be configured to have the same reserved channels. Reserving the network channel will result in undefined behavior.

The reserved channels array is not stored in permanent memory. To reserve channels, function lib_settings->setReservedChannels() has to be called in App_init() before the stack is started.

Parameters

channels	Pointer to bit array to load the reserved channels Each set bit marks the channel as reserved LSB of first byte is channel 1, MSB of first byte is channel 7, LSB of second byte is channel 8, an so on
num_bytes	Number of bytes pointed by `channels_p`

Returns: Result code, APP_RES_OK if successful, APP_RES_INVALID_NULL_POINTER if channels_p is NULL, APP_RES_INVALID_STACK_STATE if stack is running, APP_RES_INVALID_VALUE if a bit in channels_p is set for a channel larger than the maximum channel number

Note: channels_p bit array can be shorter than the maximum number of channels. Remaining channels are marked as not reserved; In the current implementation, reserved channels are not stored in persistent memory. Application must call setReservedChannels() in App_init()

Macro Definition Documentation

◆ APP_LIB_SETTINGS_AES_KEY_NUM_BYTES

#define APP_LIB_SETTINGS_AES_KEY_NUM_BYTES 16

AES key size in bytes.

This macro can be used as a buffer size for storing or copying a 128-bit AES key, or the 16-byte feature lock key. The feature lock key is not an AES-128 key, but it is guaranteed to be the same size as an AES-128 key.

Examples: provisioning_proxy/app.c.
