ZPS_tsAplZdpMgmtNwkUpdateReq#

This structure is used by the function ZPS_eAplZdpMgmtNwkUpdateRequest(). It requests an update of network parameters related to radio communication and may optionally initiate an energy scan in the 2400-MHz band.

The ZPS_tsAplZdpMgmtNwkUpdateReqstructure is detailed below.

typedef struct {

uint32 u32ScanChannels; uint8 u8ScanDuration; uint8 u8ScanCount; uint8 u8NwkUpdateId;

uint16 u16NwkManagerAddr;

} ZPS_tsAplZdpMgmtNwkUpdateReq;

where:

u32ScanChannelsis a bitmask of the radio channels to be scanned (‘1’ means scan, ‘0’ means do not scan):
- Bits 0 to 26 respectively represent channels 0 to 26 (only bits 11 to 26 are relevant to the 2400-MHz band)
- Bits 27 to 31 are reserved
u8ScanDurationis a key value used to determine the action to be taken, as follows:
- 0x00-0x05: Indicates that an energy scan is required and determines the time to be spent scanning each channel - this time is proportional to 2u8ScanDuration+1. The set of channels to scan is specified through

u32ScanChannelsand the maximum number of scans is equal to the value of u8ScanCount. Valid for unicasts only

0x06-0xFD: Reserved
0xFE: Indicates that radio channel is to be changed to single channel specified through u32ScanChannelsand that network manager address to be set to that specified through u16NwkManagerAddr. Valid for broadcasts only
0xFF: Indicates that stored radio channel mask to be updated with that specified through u32ScanChannels(but scan not required). Valid for broadcasts only.
u8ScanCountis the number of energy scans to be conducted and reported. Valid only if a scan has been enabled through u8ScanDuration(0x00-0x05)
u8NwkUpdateIdis a value set by the Network Channel Manager before the request is sent. Valid only if u8ScanDurationset to 0xFE or 0xFF
u16NwkManagerAddris the 16-bit network address of the Network Manager (node nominated to manage radio-band operation of network). Valid only if u8ScanDurationset to 0xFF
