Explicit Addressing Command Request - 0x11
Description
This frame type contains the DigiMesh routing information for a remote device on the network. This
route information can be used to diagnose marginal links between devices across multiple hops.
This frame type is emitted in response to a DigiMesh unicast transmission request which has Trace
Routing or NACK enabled. See Trace route option and NACK messages for more information.
Format
Offset Size Frame Field Description
0 8-bit Start
Delimiter
Indicates the start of an API frame.
1 16-bit Length Number of bytes between the length and checksum.
3 8-bit Frame type
Route Information - 0x8D
4 8-bit Source event
Event that caused the route information to be generated:
0x11= NACK
0x12 = Trace route
5 8-bit Data length The number of bytes that follow, excluding the checksum.If the
length increases, new items have been added to the end of the
list for future revisions.
6 32-bit Timestamp System timer value on the node generating the Route Information
Packet.The timestamp is in microseconds. Only use this value for
relative time measurements because the time stamp count
restarts approximately every hour.
10 8-bit ACK timeout
count
The number of MAC ACK timeouts that occur.
11 8-bit TX blocked
count
The number of times the transmission was blocked due to
reception in progress.
12 8-bit Reserved Not used.
14 64-bit
Destination
address
The 64-bit IEEE address of the final destination node of this
network-level transmission.
21 64-bit Source
address
The 64-bit IEEEaddress of the source node of this network-level
transmission.
29 64-bit Responder The 64-bit IEEE address of the node that generates this Route
