5.16 DUT Versions Command (DutVersionsReq, DutVersionsAns) 459
460
The DutVersionsReq command sent by the TCL requests the DUT to provide its firmware 461
version, Link Layer specification [TS001] version and Regional Parameters specification 462
[RP002] version. This command has no payload. 463
464
The DUT answers to the DutVersionsReq with a DutVersionsAns command. 465
466
Fields
FwVersion LrwanVersion LrwanRpVersion
Size (octets) 4 4 4
Table 15: DutVersionsAns fields 467
The versions (FwVersion, LrwanVersion and LrwanRpVersion) fields SHALL be 468
encoded as Major.Minor.Patch.Revision: 1 octet for Major, 1 octet for Minor, 1 469
octet for Patch and 1 octet for Revision. [Semantic Versioning 2.0.0: https://semver.org/] 470

Note: In some regions (i.e: US915) the answer to this request will not fit 472
the allowed frame size at lowest data rates. As such the TCL may only 473
issue the DutVersionReq when the DUT is set with a data rate allowing 474
the DutVersionAns to fit the corresponding frame size. 475
