XBee module comparison
XBee operation
- Transparent operation: modules are configured using AT commands and API operations are not supported. All UART data received is queued for RF transmission. Device uses DH and DL to send data.
- Application Programming Interface operation (API): is an alternative to the default Transparent operation. The frame-based API extends the level to which a host application can interact with the networking capabilities of the module.
XBee modes (states)
- Idle mode: listens for incoming RF data
- Transmit mode: device establishes PAN id and destination id and sends data accordingly
- Receive mode (if a valid RF packet is received)
- Command mode: To modify or read parameters, the module must first enter into Command mode - a state in which incoming serial characters are interpreted as commands
