When enabled the radio will send a packet twice if the serial input buffer has less than 256 bytes in it. The 2nd send is marked as a resend and discarded by the receiving radio if it got the first packet OK. This makes a big difference to the link quality, especially for uplink commands. The 3DR Radios have 2 status LEDs, one red and one green. green LED blinking - searching for another radio green LED solid - link is established with another radio red LED flashing - transmitting data red LED solid - in firmware update mode RSSI MAVLINK enables/disables MAVLink packet framing. This tries to align radio packets to MAVLink packet boundaries, which makes a big difference to what happens to the MAVLink stream when you lose a packet. Min Freq Duty Cycle Version AIR_SPEED is the inter-radio data rate in rounded kbps. So 128 means 128kbps. Max is 192, min is 2. I would not recommend values below 16 as the frequency hopping and tdm sync times get too long. Copy Required Items to Remote Max Freq LBT Rssi # of Channels Save Settings the percentage of time to allow transmit NETID is a 16 bit 'network ID'. This is used to seed the frequency hopping sequence and to identify packets as coming from the right radio. Make sure you use a different NETID from anyone else running the same sort of radio in the area.

The 2nd send is marked as a resend and discarded by the receiving radio if it got the first packet OK. This makes a big difference to the link quality, especially for uplink commands. minimum frequency in kHz Air Speed Baud Format ECC is to enable/disable the golay error correcting code. It defaults to off. If you enable it then you packets take twice as many bytes to send, so you lose half your air bandwidth, but it can correct up to 3 bit errors per 12 bits of data. Use this for long range, usually in combination with a lower air data rate. The golay decode takes 20 microsecond per transmitted byte (40 microseconds per user data byte) which means you will also be a bit CPU constrained at the highest air data rates. So you usually use golay at 128kbps or less. minimum frequency in kHz ECC is to enable/disable the golay error correcting code. It defaults to off.
