QLRS FW supports E32-TTL-1W and E32-TTL-100 HW + similar 868 modules

Maximum range of this LRS has not been tested yet. You are welcome to be the first who will beat current 12km flight, but stop asking how far will it work - too far!
QLRS supposed to provide better range than any other LRS that uses FSK modulation such as OpenLRS, ULRS etc.


Why is this project not opensource? Just because.

When I decide to stop development and there will be some not fixed bugs, i will release source code, don't worry.
If you are interested in any particular piece of coding i can share it no problem...

This is current info on supported protocols:
TX IN supports CPPM up to 16ch, and PXX (also know as XJT D8 and D16) input protocol. Sbus will come soon.
RX OUT supports CPPM up to 16ch or SBUS (it should work without external inverter).


40km flight
Lora vs FSK
RF LoRa link is 6835.94 bps
1.2GHz interference measurements
crappy 868MHz antennas
RF channel number included in payload, for better synchronization
ABLomas failed to use modules but all of them work! -> Why.
no need to solder anything to swd port

E62 module
E46-TTL-1W module
E32-433T30S module
Ebyte vs AS
