EmberZNet serial protocol

Table 76.

joinNetwork

Name: joinNetwork

ID: 0x1F

Description:

Causes the stack to associate with the network using the specified network parameters. It can take several seconds

for the stack to associate with the local network. Do not send messages until the stackStatusHandler callback

informs you that the stack is up.

Command parameters:

EmberNodeType nodeType

Specification of the role that this node will have in the network. This role

must not be EMBER_COORDINATOR. To be a coordinator, use the

formNetwork

command.

EmberNetworkParameters

Specification of the network with which the node should associate.

boolean joinSecurely

If true, the node uses the current key to secure messages during the joining

process. The proper value for secured networks depends upon their

configuration. Some networks use unsecured joining and distribute the key

from the coordinator. Other networks require secure joining and accept only

nodes that know the correct key. This value has no effect if the security

level is 0.

Response parameters:

EmberStatus status

An EmberStatus value indicating success or the reason for failure.

Table 77.

scanAndFormNetwork

Name: scanAndFormNetwork

ID: 0x4F

Description:

Scan for an available channel and PAN ID then form a network. This performs the following actions: 1. Performs an

energy scan on the indicated channels and randomly chooses one from amongst those with the least average

energy. 2. Randomly picks a PAN ID that does not appear during an active scan on the chosen channel. 3. Forms a

network using the chosen channel and PAN ID. If any errors occur the status code is passed to the

scanErrorHandler

callback and no network is formed. Success is indicated when the stackStatusHandler

callback is invoked with the EMBER_NETWORK_UP status value.

Command parameters:

int32u channelMask

Bits set as 1 indicate that this particular channel should be scanned. Bits

set to 0 indicate that this particular channel should not be scanned. For

example, a channelMask value of 0x00000001 would indicate that only

channel 0 should be scanned. Valid channels range from 11 to 26 inclusive.

This translates to a channel mask value of 0x07FFF800.

int8s radioTxPower

A power setting, in dBm.

Response parameters: None

Table 78.

scanAndJoinNetwork

Name: scanAndJoinNetwork

ID: 0x50

Description: Scan and join a network. This performs the following actions: 1. Does an active scan to find a network

that uses our stack profile and currently allows new nodes to join. 2. Joins the chosen network. If any errors occur

the status code is passed to the scanErrorHandler callback and no network is joined. Success is indicated

when the stackStatusHandler callback is invoked with the EMBER_NETWORK_UP status value.
