iFlight FC not communicating with RadioMaster TX16S on 4.5

[karmic lichen]

Hi I have a few drones I updated to 4.5 recently and all but one worked with no issues at all. I have an iFlight SucceX E-f722 stack, Caddx Vista and Crossfire on the 5" that has the issue. I flew the drone on 4.4 the day before updating with no crashes or anything abnormal but i still checked all wires and connections and found no issues. My RadioMaster is still connected to my crossfire rx and my vtx is still connected and outputting videos but the drone will not arm or anything sice i updated. When I am plugged into the PC on BetaFlight on the Receiver tab non of the bars move showing that its not receiving inputs as well. I am on Configurator 10.10.0 and here is my CLI DIFF ALL info # version

Betaflight / STM32F7X2 (S7X2) 4.5.0 Apr 28 2024 / 18:21:52 (c155f5830) MSP API: 1.46

sorry about that

[vital willow]

doesn't look like you have a port set up with Serial RX

just to make sure, can you get a screenshot of the Ports tab?

[vital willow]

yea okay, matches up

you need to enable Serial RX on the UART that your receiver is connected to

[karmic lichen]

ok that makes perfect sense thank you for the help and sorry i'm still learning

[vital willow]

it's fine

[karmic lichen]

I have enabled the Serial RX like is says in the manual for the FC and i am still having the same issue. Is there something else that could be preventing it from communicating still?

The RX plugs into the board along with the VTX so i wouldn't have them on a different UART than what the manual shows i dont think

Not sure if this could help. @vital willow

It looks like you have your receiver wired to UART 2, but you have SerialRX set to UART 1 in Betaflight

[karmic lichen]

this is how its supposted to be i think and the FC has a blue light that turns on when i arm and flashes when i flip my beeper switch but the motors dont arm and it doesnt beep either. I'm sorry im have so much trouble. i normally figure this stuff out myself but this time im lost

So its showing on BetaFlight that all switches and everything Transmitter related is working but my motors wont arm and my beeper doesnt work so it may be something other than BetaFlight im guessing.

im assuming this is what you needed?

[soft scroll]

Do you not have a VTX?

[karmic lichen]

I do but im new to this so i didnt know exactly what you needed. i apologize

i have a Vista

[soft scroll]

It's just not detecting the OSD

Can you go to the CLI tab, type dump and post the output?

[soft scroll]

Copy and paste this into the CLI tab:

serial 0 131073 115200 57600 0 115200
set motor_pwm_protocol = DSHOT300
set pid_process_denom = 2
save```

[karmic lichen]

ok i just did that and here is the dump file after i did it.

[soft scroll]

Can you post the output of status now? Can you arm?

[karmic lichen]

i still can not arm and yes give me one second

What warnings are shown in the OSD when you try to arm?

[brisk frigate]

disable bitbang when dshot_bidir is disabled otherwise enable

[karmic lichen]

deal! how do i do that? Also no warnings show up im about to post a pic of the OSD

[brisk frigate]

set dshot_bitbang = OFF
save

[karmic lichen]

THAT FIXED IT!!

Thank you all so much

[soft scroll]

Is this a new known issue? 😅

[brisk frigate]

@soft scroll this has changed just before release

only reason could be https://github.com/betaflight/betaflight/pull/13589

[soft scroll]

Good to know. Does it only affect F722?

[brisk frigate]

Was working on it in https://github.com/betaflight/betaflight/pull/13213 months ago - but was scheduled for 4.6

Not sure yet
