The actual channel frequency in Hz is 601 100 x Frequency, whereby values representing frequencies below 100 MHz are reserved 602 for future use. 603 604 The TxPower field is an 8-bit signed integer. The value in dBm represents the output power 605 applied to the CW mode. 606 607 Example: If the DUT receives 7 bytes on port 224, [0x7D 0x08 0x00 608 0xD8 0xB2 0x83 0x0E], (0x7D indicating the command ID), it SHALL 609 enter the CW mode for 8 seconds using frequency 863.1 MHz and 14 610 dBm. 611 5.22 DUT Disables FPort 224 (DutFPort224DisableReq) 612 613 The DutFPort224DisableReq command has no payload. 614 615 instructs the DUT to disable access to FPort 224 and executes a full reset of the DUT. 616 5.23 DUT Versions Command (DutVersionsReq, DutVersionsAns) 617 618 The DutVersionsReq command requests the DUT to provide its firmware version, [TS001] 619 version, and [RP002] version. This command has no payload. 620 621 The DUT answers the DutVersionsReq with a DutVersionsAns command. 622 623 Size (octets) 4 4 4 Fields FwVersion LrwanVersion LrwanRpVersion Table 25: DutVersionsAns 624 The version (FwVersion, LrwanVersion, and LrwanRpVersion) fields SHALL be 625 encoded as Major.Minor.Patch.Revision: 1 octet for Major, 1 octet for Minor, 1 octet 626 for Patch and 1 octet for Revision. [Semantic Versioning 2.0.0: https://semver.org/]. 627 628 Note: In some regions, (e.g., US915), the answer to this request will not 629 fit the allowed frame size at the lowest data rates. As such, the TCL may 630 only issue the DutVersionReq when the DUT is set with a data rate 631 allowing the DutVersionAns to fit the corresponding frame size. 632
