With OrangeRX I get PWM output on pins (a servo moves as expected) but no PPM nor SBUS.\r\nThe funny thing is I can see the PPM on channel 5 using an oscilloscope but it has a tendency to \"move around\" - can't actually describe it better. Please see attached 2 screens (first is from the tiny PPM receiver that works, second is from the OrangeRX OpenLRS receiver's PPM output.\r\n\r\n* _Steps needed to reproduce the problem_\r\n- Use OMNIBUS F4 v2 board\r\n- Updated firmware to 1.9.1\r\n- Configure the receiver to output PPM on channel 6 (described on the board as channel 5 because on channel 1 there's the RSSI output)\r\n- Connect the OrangeRX OpenLRS TX and RX\r\n- Make sure the OrangeRX link emits PPM on the designated pin using an osciloscope\r\n- Open iNAV\r\n- Ensure no serial receivers are configured on the ports tab\r\n- Ensure the receiver is set to PPM\r\n- Navigate to \"receiver\" tab and see the bars not moving at all\r\n\r\n* _Expected Results_\r\nOrangeRX PPM and SBUS signals should be properly decoded.\r\n\r\n* _Actual Results_\r\nOrangeRX PPM and SBUS signals are not recognized.\r\n\r\nTo be blunt about it I don't really care much for SBUS. I am flying a plane so fast responses don't really matter as much as nice wiring. That's the reason I have primarily chosen PPM. It works with all other receivers, outputs PPM on OrangeRX LRS RX too but iNAV (and betaflight for that matter) don't interpret that as valid signal.\r\n"},"comment":{"url":"https://api.github.com/repos/iNavFlight/inav/issues/comments/387522217","html_url":"https://github.com/iNavFlight/inav/issues/3151#issuecomment-387522217","issue_url":"https://api.github.com/repos/iNavFlight/inav/issues/3151","id":387522217,"user":{"login":"padcom","id":553994,"avatar_url":"https://avatars0.githubusercontent.com/u/553994?v=4","gravatar_id":"","url":"https://api.github.com/users/padcom","html_url":"https://github.com/padcom","followers_url":"https://api.github.com/users/padcom/followers","following_url":"https://api.github.com/users/padcom/following{/other_user}","gists_url":"https://api.github.com/users/padcom/gists{/gist_id}","starred_url":"https://api.github.com/users/padcom/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/padcom/subscriptions","organizations_url":"https://api.github.com/users/padcom/orgs","repos_url":"https://api.github.com/users/padcom/repos","events_url":"https://api.github.com/users/padcom/events{/privacy}","received_events_url":"https://api.github.com/users/padcom/received_events","type":"User","site_admin":false},"created_at":"2018-05-08T19:53:09Z","updated_at":"2018-05-08T19:53:09Z","author_association":"NONE","body":"Done."}}
