The CanSat RF communication is done with the help of an XBee-PRO ZB S2B module w/ U.Fl antenna connector.
Board connectors
The connection to the module is done through following pins:

Setup
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 module can be configured via a serial or USB programmer board with the XCTU application.
Coordinator
The XBee module on the CanSat connects to a PC via a ZigBee Coordinator (ZC).
The coordinator is configured as an API ZC.
CanSat modules
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).
The further 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
AT commands
The communication can be configured via AT commands.
AT mode is entered after a +++
input.
The following example shows a terminal connexion to an XBee device in AT mode:
