TO (Transmit Options)
This command applies to the XBee 3 Zigbee 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 |
|---|---|
| 0 | Disable MAC acknowledgments (retries) and route repair for unicast traffic. |
| 4 | Send data securely—requires secure session be established with destination. Enabling this bit will reduce maximum payload size by 4 bytes. |
| 5 |
Enable APS end-to-end encryption (if EE = 1). Enabling this bit will reduce the maximum payload size by 9 bytes. |
| 6 | Use extended timeout. |
Default
0
