The following applications are currently implemented:

1. dw1000_tx: simple periodic transmitter. Takes no parameters.

2. dw1000_rx: simple receiver that continuously listens for packets. Takes no parameters.

3. dw1000_rx_cir: like simple receiver but also outputs the CIR (channel impulse respone) for each reception to the console. Takes no parameters.

4. dw1000_twr_resp: adapted ranging application using one polling and one response message. Also outputs the entire CIR in a file. Takes 2 parameters:

5. • INIT or RESP: Choose which device is the INITIATOR or RESPONDER
   • <exp_number>: An unsigned integer used for naming the output.

   Output files have the naming scheme exp<exp_number>_msg<msg_number>_I/R.csv. The <msg_number> is modulo 256.
