EmberZNet serial protocol

SN260

62/88

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

scanAndformNetwork

command.

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.

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: None

Table 78.

scanAndJoinNetwork (continued)

Table 79.

scanErrorHandler

Name: scanErrorHandler

ID: 0x51

Description: This callback is invoked if an error occurs while attempting to scanAndFormNetwork or

scanAndJoinNetwork

This frame is a response to the callback command.

Response parameters:

EmberStatus status

An EmberStatus value indicating the reason for the scanAndFormNetwork

or scanAndJoinNetwork failure.

Table 80.

leaveNetwork

Name: leaveNetwork

ID: 0x20

Description: Causes the stack to leave the current network. This generates a stackStatusHandler callback to

indicate that the network is down. The radio will not be used until after sending a formNetwork or joinNetwork

command.

Command parameters: None

Response parameters:

EmberStatus status

An EmberStatus value indicating success or the reason for failure.

Table 81.

mobileNodeHasMoved

Name: mobileNodeHasMoved

ID: 0x21

Description:

Informs the stack that contact with the network has been lost. Only devices that are joined to a network with a node

type of EMBER_MOBILE_END_DEVICE may call this function. This generates a stackStatusHandler callback

to indicate that the network is down. The stack will try to re-establish contact with the network. A second

stackStatusHandler

callback indicates either the success or the failure of the attempt.

Command parameters: None
