2.4 GHz / 868 / 915 MHz
RC control links
Where the sticks are on every model control link in earshot: a bar per channel in microseconds, with the frame rate and whether the handset is asking to arm.
A control link is the one signal that says what the pilot is doing rather than what the aircraft is. The control view draws each channel as a bar in microseconds, live, with the packet rate and the link level beside it, and flags the arm switch.
ExpressLRS is the link the receiver places for itself, on 2.4 GHz and on the 868 and 915 MHz bands. FrSky ACCST, FlySky AFHDS-2A and XN297 toy remotes are read as well, the last with its address and payload.
What comes out
- Channel positions in microseconds, live
- Packet rate and link level
- Arm request, where the protocol carries it
- Binding phrase hash or address, depending on the link
