TO (Transmit Options)
This command applies to the XBee 3 DigiMesh RF Module.
A bitfield that configures the advanced options used for outgoing data transmissions from a device operating in Transparent mode (AP = 0).
When operating in API mode, if the Transmit Options field in the API frame is 0, the TO parameter value will be used instead.
Sending a unicast message with MAC ACKs disabled is not intended to be a reliable form of communication, as no ACKs are produced by recipients.
Parameter range
0 - 0xFF
Bit field:
Unused bits must be set to 0. These bits may be logically OR'ed together:
| Bit | Meaning | Description |
|---|---|---|
| 0 | Disable ACK | Disable MAC acknowledgments (retries) for unicast traffic. |
| 1 | Disable RD | Disable Route Discovery on all DigiMesh unicasts. |
| 2 | NACK | Enable a NACK messages on all DigiMesh API packets. |
| 3 | Trace Route | Enable a Trace Route on all DigiMesh API packets. |
| 4 | Secure Session | Send data securely—requires secure session be established with destination. Enabling this bit will reduce maximum payload size by 4 bytes. |
| 6,7 | Delivery method |
b’00 = <invalid option> b’01 = Point-multipoint (0x40) b'10 = Directed Broadcast (0x80) b’11 = DigiMesh (0xC0) |
