2 Sleep Mode of the Transceiver vs. Sleep Mode of the SBC

Before discussing the various wake up methods, a few concepts must be discussed. The transceiver integrated into an SBC have some independence from the rest of the SBC, meaning that the mode of the transceiver does not reflect the mode of the entire SBC. However, note that the SBCs current state determines what modes are available. This means wake can have two different meanings: waking the SBC or waking the transceiver. In general, for the transceiver to be fully functioned and communicating the SBC must be in normal mode; however, the SBC being in normal mode does not verify that the transceiver is active. The transceiver can be in a wake-capable state. The main result is that a wake signal can come to the SBC while the SBC is awake but be meant for the transceiver specifically. See a device specific data sheet for more information on the transceiver and SBC modes.
