4.3 Quickstart example

Sending and receiving: Hello World

Connect the two devices (modules, EV-boards or USB dongles) to a PC. You may need to

install FTDI VCP drivers manually (see ) or using windows update. A minimum distance

of 2 meters between the two devices should be kept at all time to avoid over modulation of

the receiver.

A terminal program, for example hterm, is used to perform the communication via COM

ports. The two corresponding COM ports have to be selected and opened with a default

conﬁguration of 115200 baud, 8 Data Bits, 1 Stop Bit and Parity set to none (8n1).

Make sure the received data is shown also as hex by enabling the corresponding checkbox:

As soon as the module is ready for operation (at start-up or after a reset), the device sends

CMD_RESET_IND

message on the UART. Eventually the reset button has to be pushed (or

CMD_RESET_REQ

performed) to trigger a reset and see this message.

Next, the command interface can be used to conﬁgure the module or to transmit data. The

MAC_DefaultAddressMode

is 0, which means that all radio frames are broadcasts that can be

received by any other radio compatible device in default settings.
