Functional Description 4.1 Overview 4.1.1 LRM2 and PA Radio

. Figure 4.1 LRM2 +PA Radio The Silicon Labs ERF32FG13 SoC is located between the host interface and the RF interface, providing decoupling between host and RF interface. The EFR32FG13 SoC has sufficient buffer space for one telegram. As shown later, telegram processing is defined to minimize delays, so to provide a transparent-like behavior. Sub-GHz will support different frequency bands to support different regions & supported frequency bands are mentioned below:

Propriety Sub-GHz protocol:

460MHz 868MHz 4.1.2 Data Communication Model & Definitions The communication model defines some of the terminology used in the rest of this document. Figure 4.2 - Data communication model HostLRM Radio ModuleHost Data BufferTx/RxTransmit Telegram FramesReceive Telegram FramesRF packetsLRM Host InterfaceLRM RF Interface LRM2+PA Radio Module Document p/n: 9S02-8969-A003 Rev.A Functional Description

- The LRM2 Radio Module is used to communicate telegrams between hosts. In Unity context, hosts are OCU and MCU CPU boards. The LRM2 has two interfaces: a Host Interface and a RF Interface.

- Transmit and Received Telegrams are relayed through the LRM2 Host Data Buffer. This buffer is capable to hold only one telegram at a time. The purpose of this buffer is to relax host timings requirements, and to allow decoupling between Host Interface and RF Interface data rates.

- Telegrams sent/received on the Host Interface and RF interface are encapsulated into frames to improve synchronization.

- The LRM2 does not perform any processing on the telegrams content; it controls only the frames overhead. 4.2 Telegram Transmission Transmit frames have two fields:

- Telegram length (number of bytes). The length is used by the CPU to control the transmission process.

- Telegram (maximum 254 bytes). The content of the telegram is defined by the application. For Unity application, this is the Unity Telegram beginning with the Scrambling byte, the TID and terminated with the 16bits CRC, as defined in ref [2]. Figure 4.3 - Transmit Telegram frame format 4.3 Telegram Reception Each RF packet received by the LRM2 is sent to the host interface, followed by its RSSI. Also, in order to ensure receive telegram frame synchronization (i.e. unambiguous detection of the start of the frame), the frame is encapsulated according to SLIP framing. SLIP framing is very simple to decode. It is described in section Error!

Reference source not found.. Receive frame fields are:

SOF (Start-of-Frame character). This is part of SLIP encapsulation.

- Length of the Telegram field (number of bytes), not counting RSSI fields and any additional control characters introduced for SLIP encapsulation.

- Telegram (maximum 254 bytes). The content of the telegram is defined by the application.

- RSSI: Received signal strength for this frame. RSSI is an 8 bits integer value, expressed in dBm. Range;-128 to

+127 dBm.

- All parameters can be read and written only in CONFIG mode. The definition of the configuration registers is given in reference [3]. This section addresses the basic description of all these three methods. 5.1 Console Interface The Sub-GHz serial interface configuration port is enabled by asserting !CONFIG signal; the serial interface is automatically reconfigured in asynchronous mode, running at 38400bps, 8N1. All ASCII strings received are interpreted as configuration commands. This mode is particularly useful for stand-alone testing, when the unit can be controlled from a PC or by an operator/tester using a terminal emulation program. 5.1.1 Write command wrCmd register value , where:

wrCmd = write command. w or wr can be used and are equivalent register = register identification. Can use the register name or register address value = value to be written, in decimal or hexadecimal format. Hexadecimal values are preceded by 0x 5.1.2 Read command rdCmd reg where:

rdCmd= read command. r or rd can be used and are equivalent reg

= register identification. Can use the register name or register address 5.1.3 Help command helpCmd where:

helpCmd= help command. h, help or ? can be used and are equivalent. The LRM2&PA responds with the list off all available configuration registers. 5.2 Stand-Alone Test Mode The LRM2&PA can be operated in stand-alone mode for production/service tests. In this case, only a 5.0VDC supply is needed, and a RS232/TTL transceiver (like Cattron FLASHBOX) to connect to a PC serial port. 5. LRM2+PA Radio Module Document p/n: 9S02-8969-A003 Rev.A LRM2&PA Configuration Concept Figure 5.1 - LRM2 connection for stand-alone operation The LRM2&PA will support several built-in test modes to ease testing from a PC. For example a. Sub-GHz Transmission Tests

- Generation of different type of carrier: unmodulated (CW), or modulated with 101010.. or pseudo-random sequence

- Automatic generation of test RF frames with predefined content b. Sub-GHz Reception Tests

- Measure PER (packet error rate) when receiving the predefined test RF frames

- Measure RF input level c. Bluetooth Tests

- By using Silicon Labs application, Wireless Gecko, the Bluetooth channel, transmit power level, data speed could be adjusted. 21LRM, host interface26RXDTXD25!CONFIG3V3GND2722RS232 - TTL transceiver(ex: Cattron FLASHBOX)3.3VDCRS232PC, running automated testprogram, or ANSI terminalemulation software*Note: The LRM !RX_EN, !TX_EN and !RESET all have internal pull-ups, so they can be left unconnected.
