Radio Setup
✅ Open the src/bin/radio-send.rs
file.
✅ First run the program radio-send.rs
as it is. You should see new output in the output of cargo xtask serial-term
.
$ cargo xtask serial-term
deviceid=588c06af0877c8f2 channel=20 TxPower=+8dBm app=loopback.hex
received 5 bytes (CRC=Ok(0xdad9), LQI=53)
The program broadcasts a radio packet that contains the 5-byte string Hello
over channel 20 (which has a center frequency of 2450 MHz). The loopback
program running on the Dongle is listening to all packets sent over channel 20; every time it receives a new packet it reports its length and the Link Quality Indicator (LQI) metric of the transmission over the USB/serial interface. As the name implies the LQI metric indicates how good the connection between the sender and the receiver is.
