ENGINEER’S TIP
Transmitting and Receiving data with a sleeping End Device.
• Data sent to the radio over the UART while it is sleeping will be lost. If the module wakes
while receiving data over the UART, it will only see the data received since waking up.
• Incoming RF packets to the module will not keep it awake unless you enable Modify Wake
upon RX in EEPROM (EEPROM address 0x45, bit-5).
• When sending data for the module to transmit, it is recommended that the module be forced
awake using the Sleep_Int
pin until the module is finished transmitting the data. .
• While the module is being kept awake using the Sleep_Int
pin, it will send data requests to
its Parent Device based on the Wake Poll rate specified in EEPROM (EEPROM address
0x3C) for as long as it is awake.
• A Parent will only store data for a sleeping End Device for a maximum amount of time
specified by the Parent Hold Message EEPROM parameter (EEPROM address 0x39).
