Page 4: Introduction
WIRELESS CONNECTIVITY & SENSORS ANR001 - Metis-II Repeater Mode 1 Introduction Starting with firmware version 2.8.0 the Metis-II include a feature to enable receiving, buffering, delaying and forwarding radio frames better known as single-hop unidirectional repeater func- tionality. WE order code... - Page 5 WIRELESS CONNECTIVITY & SENSORS ANR001 - Metis-II Repeater Mode Frames that have an Extended Link Layer (ELL) as first Control Information Field (Ci- Field). This ELL has a Communication Control Field (CC-Field) which provides a Hop Count Subfield (H-Field). The first Ci-Field can be followed by one or multiple further Ci-Field(s).

Page 6: Using The Included Wireless M-Bus Repeater
WIRELESS CONNECTIVITY & SENSORS ANR001 - Metis-II Repeater Mode 3 Using the included wireless M-BUS repeater The repeater mode runs in parallel to the normal module functions as sending and receiving frames without interfering the normal operations of the module or the reachability of the module via UART. - Page 7 WIRELESS CONNECTIVITY & SENSORS ANR001 - Metis-II Repeater Mode required to use the CMD_DATA_CLR_PRELOAD_REQ command ( 0xFF 31 00 CE ) in order to clear the preloaded frame from the queue. Preloading is obsolete since firmware version 2.8.0 and shall not be used any- more.

Page 8: Configuration Using Cmd_Set_Req
WIRELESS CONNECTIVITY & SENSORS ANR001 - Metis-II Repeater Mode 3.1 Configuration using CMD_SET_REQ By using the following CMD_SET_REQ sequence followed by a CMD_RESET_REQ the settings to enable the repeater mode will be applied to the non-volatile memory of the module. - Page 9 WIRELESS CONNECTIVITY & SENSORS ANR001 - Metis-II Repeater Mode Set the Mode_Preselect to either S2 or C2_T2_Other For using S2 mode a reconfiguration is not required. For C2_T2_Other mode use CMD_SET_REQ: 0xFF 09 03 46 01 09 BB Factory default: S2 mode...

Page 10: Supported Wireless M-Bus Modes For The Repeater
WIRELESS CONNECTIVITY & SENSORS ANR001 - Metis-II Repeater Mode 3.2 Supported wireless M-BUS modes for the repeater The single-hop unidirectional repeater requires to receive radio frames. For example all wM- BUS modes containing a "1" are send-only modes and can therefore not be used when the repeater mode shall be enabled. -
Page 11: Cmd_Rp_Data_Ind
WIRELESS CONNECTIVITY & SENSORS ANR001 - Metis-II Repeater Mode 4 CMD_RP_DATA_IND This UART frame will indicate towards the host that a frame was successfully repeated. 4.1 Example 1 The indication will share further parameters that can be used by the host system to trace the utilization of the buffers as well as to trace the duty cycle used by the repeater mode. -
