CRSF_FRAMETYPE_LINK_TX_ID

Telemetry Item / CRSFv3

Uplink (Ground to UAV) signal information - see CRSF_FRAMETYPE_LINK_STATISTICS

• uint8_t RSSI dBm (positiveized?)
• uint8_t RSSI percent
• uint8_t Link Quality
  • Uplink LQ of 0 may used to indicate a disconnected status to the handset
• int8_t SNR
• uint8_t downlink (sic) RF power - not currently populated?
• uint8_t Packet rate FPS / 10 - not currently populated?
  • e.g. 50Hz sent as 0x05 / 5
  • e.g. 150Hz sent as 0x0F / 15
  • e.g. 333Hz sent as 0x21 / 33
  • e.g. 1000Hz sent as 0x64 / 100

Usage

• Betaflight uses only RSSI dBm, RSSI percent, Link Quality, SNR (4.5.0)
• EdgeTX uses only RSSI percent, downlink power, FPS. Note both uplink and downlink RF power go into the same EdgeTX telemetry item (2.10.0)
• ExpressLRS does not generate this frame
