Missing Modules CYRF6936

Applying 3.3v to TXEN on the A7105 module might not have damaged it, wouldn't hurt to rewire it and try it.

Some alternate CYRF modules are discussed in a new thread:
www.deviationtx.com/forum/6-general-disc...ment-rf-module#41382

So yah, it sounds like a problem CYRF module, but the other modules may still work. If you can disable the CYRF module -- and I don't know how to do that -- you may still have a good A7105 or NRF module to fly with.

Let us know as this proceeds...

Think this one would just plug in and work in the Devo 10? www.ehirobo.com/walkera-wk-devo-s-mod-de...-upgrade-module.html

I guess now the next question is what caused the original CYRF module to crap out?

That's the one.

The photo of the socket shows what looks like heat damage... Is the socket in good shape?

I was using the wrong tip on the soldering iron was using a pencil tip went to a small wedge tip and it worked much better. I have taken a ohm meter and checked the to the solder joint. It was good and non of them show shorted.

Guess the next step is to order one wait for the slow boat and see what happens.

You may be able to use the transmitter if you want but with the other modules. It appears that you can disable the CYRF module in a round-about way. Presuming you install the NRF24L01 module, then in the boot cycle, if the default model.ini is using a protocol using the NRF module, you'll still get the missing module CYRF error message, but you can press enter and go into your model. Likewise if you have a model using a protocol on an installed A7105. The default model.ini file selection is shown in the TX.ini file as "current_model=2" for "model2.ini".

Let me know if you get different results!

That's interesting the 1st model.ini file was for my Blade Nano QX 3D which uses the CYRF module. That would tell me if the transmitter is going to work. I'll solder the nrf24l01 module back in and give it a try.

I ordered a new CYRF module should be here in a couple of weeks.

That does work but it's real chosey about the protocol, tried SymaX, didn't work so I went through the list and picked one of the older ones, Y2x2 using that I could say OK to the CYRF module and it would go to the 1st model. I used a model1.ini for for the Tarantula that uses Y2x2 but in the ini file it's listed as Y202 if you use that it won't let you past the missing CYRF screen. Decided to try not having a protocol in the model1.ini so I left protocol blank. I was able to OK the missing CYRF module and was taken into Deviation with complete access to the menus.

Still can't get it to bind with any models. The 2 I was trying used Y2x2 and SynaX when going through the the model menu when I got to the list of available protocols every one of them had an * in-front of them. Tried changing the hardware.ini froom A13 to A14 and back made no difference. Had another NRF24L01 module tried that. Went and check the wiring and discovered that I had crossed the CE & CSN and MISO was missing I had used IRQ. I used a plug that I had with ribbon on it when I ohmed out the plug and cable the numbering was backwards to the moduleList. Had another plug and ribbon cable so I redid my wiring diagram using my numbering instead of theirs and look at when pin was which line on the module picture. Soldered the new one in and still no protocols. I have tried several different DFU nightly builds and tried hexfet's test build which I had read was good. Went back and ohmed out all the wires to make sure they were in the proper place and all was good. Now if I can get past this protocol thing I might be able to fly.

I've been looking at other installs of the nrf24l01 & a7105 modules no one really mentioned the size wire they used but it all looks bigger that what used. So I would have a plug for the nrf24l01 I used a ribbon cable from a computer and the wires are pretty small. So is it possible that I'm getting to much resistance and no enough power to the module?

It seems unlikely that it would be a problem. My builds are mostly 26 or 28 Gauge stranded wire, and your computer cable is probably 24-26. So not much difference. I like having a socket, too, and it does fit into the 7e , but it has to be positioned right. You've got more options with a right-angle socket and ribbon cable.

Mine is the Devo 10 so room really isn't that big of an issue. It was just a thought. I have a new CYRF module on the way so we'll see what happens when it shows up. I guess if it still doesn't work I really dorked it up good.

Added
force=1 to the hardware.ini below the modules section.

It did make all the protocols appear to be working yet they are not.

The next thing to try is ground the nrf24l01 to the CYRF

The new CYRF module arrived today. Went down & removed the nrf24l01. Removed the existing CYRF module and replaced it with the new one. Turned on the Devo 10 and got the same message missing CYRf6936 module. I did comment out all the other modules in the hardware.ini

Looked real close at the solder spots on the CYRF socket didn't see any shorts. Also checked with a mm no shorts between adjusant post.

Anything else I should look at or try before I trash it?

Do you have a higher resolution pic of the CYRF socket on the Tx than what you previously posted? Can't really see what it looks like in that pic when zooming in on it.

It may be possible to use the CYRF on your MM. But I can't find the documentation for this. You need to plug in the 5v pin to a source on the Devo -- if you don't have the CYRF installed you can probably use the unused 5v socket. You need to change the address in the hardware.ini, but I wasn't able to find the documentation in the forums or wiki files. I have identified the location of the socket. So maybe someone with more hardware experience can help out with the address of the CYRF module when it is installed on the MM?

I try taking a picture with my Dale instead of my phone and see if it's any better.

I had the Nrf24l01 installed and could never get it to bind with any quads. Tried the X11 & the tarantula x6. The protocols all had the * in front of them. If I added force=1 to the hardware.ini the * disappeared but still nothing would bind.

Guess I'll install the mm and see what happens.

I was looking at the previous photo of the CYRF module and I saw traces that didn't look good. Traced the SCK back up to the square black chip above the CYRF socket. Then checked it with an ohm meter, circuit open. Here's what I hope a better picture.

Another angle

What do you guys think?

Yes, that SCK pad looks suspect. Still can't see it very well, but I would venture a guess that you have melted through a trace, or torn a pad from it's trace.

Looks like you have put way too much heat to the CYRF plug and board from what I can see.

Maybe this one will be better

The SCK line being broken would explain why the NRF24L01 module wouldn't work when I tried putting just it in and tricking Deviation to bypass the missing CYRF module.

I have tried bridging the broken SCK line without success so far.
