Read Using ATSI 16 Notes When the radio is in deep sleep you can not discover or connect to it UART RX line needs to be pulled high if not active before power is applied to the radio module If there is an active RF link the device will need Sniff Mode enabled to allow it to drop into sleep mode when there is no traffic When in deep sleep the UART will miss the first character while waking up Send a preamble byte to allow it to wake up and immediately thereafter send the AT Command or data in less than 1 second or the device will go back to deep sleep again If you are using PIO 3 CPU interrupt a preamble byte is not needed No bytes are lost if sending commands down over the remote RF link side This setting is stored in flash and does not require a reset to take affect Takes approx 1 second before the current will drop down to 25 50uA Allow 5msec for the CPU unit to come out of deep sleep ATSW21 4096 18 4096 18 settings along with enabling Deep Sleep Mode will result in an unconnected slave current draw of 350uA average 3 4 10 Read Memory Locations S Registers S registers refer to memory locations used for configuration The SR commands are used to read values from various registers in the radio s Flash Memory that are stored in nonvolatile memory SR21 READ PIO LEVEL Function Reads PIO logic level Format 5 21 Parameters
