I got the message like some others “Radio not ready”, “Please turn on Transmitter” when calibrating my transceiver
My RC transmitter is a Taranis X9lite using Open-TX vr 2.3.15-otx (1004ef7c)
Internal module ISRM-N 1.1.0/2.1.10FCC
The receiver is FrSky Archer R4 which is updated to the last firmware version v2.2.14 and is connected through the S-bus with the flight controller.
The receiver is registered and bound, so both are communicating
The flight controller hardware is a PixHawk 2.4.8 on 4F450 frame and got the firmware version updated to the latest PX4 version. I wanted ArduPilot but did not know which board I should select a question that was not asked selecting the PX4 firmware. I run the latest version of QGroundControl V4.4.3 under MacOS 15.3 on an M4-Pro installed using HomeBrew.
In QGC I:
- I updated the firmware to latest PX4 Stable Release v1.15.0
- Selected the correct airframe
- Calibrated all the sensors but got stuck at the calibration of the radio and continuously get the message: “Radio not ready”, “Please turn on Transmitter”
I searched the forum:
- Radio Not Ready fault during first set up (+can't fit mag 1 fault) Not helpfull
- Radio not ready turn on controller Not helpfull
- Setup MAVLINK as RC Protocol Not relevant
- How to set Pixhawk 6c Not helpful
- Pixhawk 6X Not Receiving RC Signal very similar issue it seems
- QGroundControl - Radio Setup Issue - RadioMaster TX12 MarkII CC2500 - R81-V2 Receiver did not help me.
I ordered another model of receiver but it will takes weeks before I get that one and it is ulcer if this will help. I was wondering if anybody had any suggestion on what to do next. I’m an almost retired NOOB who just built this weekend his first quadcopter that has not flown yet. I’m new to all this and slowly start to get to grips with the complexity and all the new terms. So do not fear to explain it as I was 10 year old what I’m doing wrong. Highly appreciate in advance anybody willing to help. I see there are some diagnostic tools in QGC but I’m not sure how to use them so that might be a next step.
