LRM2 Radio Module – Host Interface Specification Document p/n: 9S02-8969-A001 Rev.A Functional Description - 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.
LRM2 Radio Module – Host Interface Specification Document p/n: 9S02-8969-A001 Rev.A Functional Description - 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.
LRM2 Radio Module – Host Interface Specification Document p/n: 9S02-8969-A001 Rev.A 5. LRM2 Configuration Concept LRM2 Configuration Concept All LRM2 configuration and status parameters are accessible through addressable registers. - 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.
