gr-tenna

The goal of this project is to implement the goTenna Mesh protocol in GNU Radio. So far there are flow graphs for receiving and transmitting "Shout" messages using a USRP B200 or HackRF.

Usage

To receive messages using a USRP:

./gotenna_rx_usrp.py

To receive messages using a HackRF:

./gotenna_rx_hackrf.py

To transmit a shout message using a USRP:

./gotenna_tx_usrp.py --app-id=0x3fff --sender-gid=1234567890 --initials=XYZ --message="Hello world!"

To transmit a shout message using a HackRF:

./gotenna_tx_hackrf.py --app-id=0x3fff --sender-gid=1234567890 --initials=XYZ --message="Hello world!"
