New 4 in 1 ESC not working


#1

I bought a tiny pepper from Boldclash a couple months ago and just got around to testing it. The resource B09 which is mapped to the front port motor is not working I.e the motor doesn’t spin up when commanding from betaflight.

How do I know if it’s the ESC or the motor without resoldering the motor?

The reason I’m asking is because I bought the stack where the ESC wires were already soldered and have some black rubber insulation goo on the joints which I don’t want to scratch off unless I have to.


#2

Will resource mapping help me or could it still be either the wiring between the FC and the motor, or the motor, or the ESC? That is, even if I resource map the pin to a new pin, the signal is still going through the same FC to ESC signal wire?

I checked continuity on the motor leads before soldering on the motor and each lead had continuity.


#3

Can blheli talk to the ESC?


#4

I tried to connect to blheli a couple times a few months ago when I got the stack and it wouldn’t connect to any of my ESCs. I’ll retry a couple times when I get home from work today.

Would one bad ESC prevent blheli from connecting?


#5

It shouldn’t, no. I’m making the assumption that the tinypepper stack speaks blheli_s. If it doesn’t then that explains that part.


#6

Yeah. I read on the TinyFish documentation page that it speaks blheli_S, so hopefully it was just glitching before.

I really hope it’s just a loose signal wire and not the ESC that’s dead…

If it can’t read, say ESC 2, does that always mean that ESC 2 on the 4 in 1 is having trouble or does resource mapping change that?


#7

Connect a known working motor to the suspect esc pads and that will how what the problem is depending on whether it spins up. Substitution and elimination is the most reliable way of seeing where the problem lies. Is it a 1s Fishpepper esc? I’ve built a few of them. They are blheli-s chips so should show up in blheli suite. Resource mapping won’t help unless the cause is a lost pad or broken pin as there’s little else to map to on that fc, led strip only I think.


#8

I’ve tried connecting to BLheli multiple times and I keep getting the same error:

It seems to recognize my device, but refuses to connect. I downloaded both drivers from the links on the GUI and this BLheli just worked a week ago with my other 25A esc.

Is there some settings that I’m missing somewhere?


#9

It looks like the passthrough from fc to esc isn’t working as its recognising the board correctly. I’d try flashing the fc with newer version and seeing if that fixes the blheli issue.


#10

I tried to reflash it, but that’s not working either…

I tried to short the boot pins multiple times, but I can’t get the FC into bootloader mode and see DFU. I tried using Zadig to replace the USB Serial driver with WinUSB driver and now I cannot even see the COM port. I tried to flash it in that mode by shorting the boot pins but that didn’t work. Luckily, restoring the USB serial driver with Zadig allows me to connect to my TinyFish FC, but I still can’t seem to flash it.

If I can’t get into BLheli and I want to reverse my motor direction (some are backward), can I just switch the two outer motor wires?

Also, if I’ve already used resource mapping on the FC, is there any way to tell which motor pads belong to which ESC signal wire so I can check the soldering?


#11

I may have a solution. The comm0 and Manual selection that show up have been, in my case, incorrect drivers on the computer side. I installed/ran ImpulseRC driverfixer and my FC, and maybe your esc, connected perfectly fine after running. I’d give it a try, see if it works.


#12

I’ll try that first thing tomorrow!

Thanks!


#13

I ran ImpulseRC driverfixer and it let me flash my FC to the most recent firmware (was running a firmware from early 2017). I tried to connect to blheli and it still is giving the same error.

Also, my motor still does not spin up. I guess I’ll have to check the solder joints now, unless there is something else I can do.

Is there any way I can narrow down which solder joint it is (it’s covered in some RTV that’s hard to scrape off)? Also, if I want to switch motor spin direction without going into BLheli (since I can’t), would reversing the two outer wires work?

#14

You ran it connecting to blheli or betaflight? Just to be sure, you can’t connect to blheli, right.


#15

Swapping any two of the three motor wires will reverse direction.

Here are the esc pads, numbered, on the underside of the fc.

These diagrams show both sides of the esc,mtheyve signal pads are rx1, rx2, rx3, rx4.
It’s an unusual layout due to space constraints.


#16

Yes. It’s just BLHeli. I could always connect to betaflight and after your suggested fix, I managed to flash my FC to the new firmware. But I still can’t connect to BLHeli…

Thanks! So I’ll do that if I can’t get into BLheli.

So, if the Resource command in the CLI says that motor 4, which is always pin B09 is not working, can I figure out which ESC # that belongs to?


#17

Could you post a couple of pics of your fc and esc so I can see how it’s orientated.


#18

Here are some pics of the stack and the wiring diagram from Boldclash.

From the orientation, I think it is ESC 3, unless resource mapping changes that?

The motor that’s marked with a 4 on the tape is the ESC that isn’t working.


#19

You have the esc facing backwards? Yes it’ll be esc3 then. So esc is on the bottom and your Lipo connects out the back? Are you resource mapping correctly for esc backwards? I am confused by your tape marked 4 on what would be motor 2 assuming fc top battery out back.


#20

Yeah. The ESC may be backward. I got the stack from boldclash so it was presoldered. I’m designing my own frame for this guy and mounting the FC on the bottom and the ESC on the top at a 45 degree angle, whoop style.

It just took so long to get the frame design right and for the motors to come in that I didn’t test the ESC until a couple days ago… hopefully it’s just a bad connection and not a bad board because it’s too late to complain to the vendor lol.
