The connection to the module is done through following pins:
|data_in||b2||in||serial link RxD|
|data_out||b4||out||serial link TxD|
|RSSI_PWM||t1||out||radio signal strength indication|
An XBee module can work in API mode, providing a complete ZigBee network, or as a simple AT modem. In order to communicate between different modules, a common PAN identifier must be set. The XBee product manual gives the setup information.
The XBee module on the CanSat connects to a PC via a ZigBee Coordinator (ZC).
The coordinator is configured as an API ZC.
The XBee module on the CanSat is configured as a ZigBee Router (ZR).
The modules are configured as AT ZRs.
They all have a distinctive MAC address, starting with the
0013A2 Organizationally Unique Identifier (OUI).
0040B8 are identical on the devices we have acquired and the last 4 hex digits are written on the board.
This address will be used by the ZC to connect to the module.
The serial port setup is:
- 115200 baud
- 8 bit, no parity
The communication can be configured via AT commands.
AT mode is entered after a
