stackStatusHandler

Name: stackStatusHandler

ID: 0x19

Description:

A callback invoked when the status of the stack changes. If the status parameter equals EMBER_NETWORK_UP,

then the getNetworkParameters command can be called to obtain the new network parameters. If any of the

parameters are being stored in nonvolatile memory by the Host, the stored values should be updated.

This frame is a response to the callback command.

Response parameters:

EmberStatus status

Stack status. One of the following: EMBER_NETWORK_UP,

EMBER_NETWORK_DOWN, EMBER_JOIN_FAILED,

EMBER_MOVE_FAILED

Table 70.

startScan

Name: startScan

ID: 0x1A

Description: This function will start a scan.

Command parameters:

EmberNetworkScanType scanType

Indicates the type of scan to be performed. Possible values:

EMBER_ENERGY_SCAN, EMBER_ACTIVE_SCAN.

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.

int8u duration

Sets the exponent of the number of scan periods, where a scan period is

960 symbols. The scan will occur for ((2^duration) + 1) scan periods.

Response parameters:

EmberStatus status

EMBER_SUCCESS signals that the scan successfully started. Possible

error responses and their meanings: EMBER_MAC_SCANNING, we are

already scanning; EMBER_MAC_JOINED_NETWORK, we are currently

joined to a network and can not begin a scan;

EMBER_MAC_BAD_SCAN_DURATION, we have set a duration value that

is not 0..14 inclusive; EMBER_MAC_INCORRECT_SCAN_TYPE, we have

requested an undefined scanning type;

EMBER_MAC_INVALID_CHANNEL_MASK, our channel mask did not

specify any valid channels.

Table 71.

energyScanResultHandler

Name: energyScanResultHandler

ID: 0x48

Description:

Reports the result of an energy scan for a single channel. The scan is not complete until the

scanCompleteHandler

callback is called.

This frame is a response to the callback command.

Response parameters:

int8u channel

The 802.15.4 channel number that was scanned.

int8u maxRssiValue

The maximum RSSI value found on the channel.
