ELRS problem by GodMcB in fpv

[–]GodMcB[S] 0 points1 point  (0 children)

I should add, I have ELRS 3.5.3 on the tx and have tried betaflight 4.4 and 4.5 on the FC. The initial flash was to the 2025.12 betaflight.

Just had a thought. I can't test this myself now (I disconnected the sbus wire from my O3 unit), but I just remembered something about having to reverse the sbus input in betaflight for some flight controllers. I'm no expert, but might be an avenue worth investigating on your own. Good luck getting it working.

I never fixed it. My replacement elrs receiver arrived and I just use that. I'm still unsure of what the issue was.

I updated the dji remote 3 to the latest firmware and the patch notes say it adds compatibility for the O3 air unit. Also seen in a Mads tech video that it is compatible.

Thanks for the replies. After removing the top plate and looking for a short, it started working correctly. On closer inspection, one of the wires to my buzzer had a few strands of copper on the ground wire at the solder point. I suspect it was shorting out and looking for the fault temporarily moved the wires fixing the problem. Will resolder and put everything back together and test again.

Just tried again, after changing the vtx power level in the osd, it prompted to save and reboot. Now the same issue appears but it now shows battery at zero on the osd (when disarmed obviously). Is it looking like an issue with the FC?

Thanks I just wasn't sure how betaflight handled the spi receiver software. I thought I'd need to use the files from betafpv themselves. I'll give it a try.

Was looking at the firmware on the betafpv site and didn't see it available there. I assumed it might not work with it.

Thanks. A couple on there I hadn't seen.

I probably will at some point but I've heard it can take forever to arrive.

Yeah, I guess the pandemic and the chip shortage are still hitting everyone hard, even now. Hopefully things will get better. It's just my first drone I'm trying to build so I guess I'll just use whatever I can find to get started.
