Transmit Status
Frame Type: 0x8B
When a TX Request is completed, the module sends a TX Status message. This message will
indicate if the packet was transmitted successfully or if there was a failure.
Example. In the above example, a unicast data transmission was sent successfully to a
destination device using a frame ID of 0x47.)
Route Information Packet
Frame Type: 0x8D
A route information packet that can be output for DigiMesh unicast transmissions on which the
NACK is enabled or the Trace Route option is enabled.
Example. The above example represents a possible Route Information Frame that could be
received when doing a trace route on a transmission from a radio with serial number
0x0013a2004052AAAA to a radio with serial number 0x0013a2004052DDDD. This particular
frame indicates that the transmission was successfully forwarded from the radio with serial
number 0x0013a2004052BBBB to the radio with serial number 0x0013a2004052CCCC.
