Flysky TH9X and Banggood 4 in 1 Module won't bind to Spektrum receiver

Post by Rod99 » Mon Jul 27, 2020 8:49 pm

I just bought a used Horizon Hobby Timber airplane. It has a Spektrum AR636A receiver with AS3X. I cannot get it to bind with my Flysky TH9X with a Banggood 4-IN-1 Multi-protocol STM32 TX Module. I am using ER9X in my transmitter. I have tried just about every combination I can think of in the Protocol settings. I have set the channel order in model setup to TAER, the Spektrum channel order. I have also tried binding with a channel order of AETR as I read in one of the Multi Protocol instructions that the module automatically remaps the AETR to TAER. My throttle is at 0 % when binding. I have reversed the throttle channel in the limits menu to check if the throttle position is a problem but no bind with throttle reversed. A quick description of the Protocol setting I think should work are 1st channel 1, Proto Multi, RxNum 0, Protocol DSM, Type DSMX-22, Power High, Option 6, Autobind No. This is the first time I have tried to bind to a Spektrum receiver, it is the only Spektrum receiver I have. I have used this transmitter for over a year flying 4 airplanes with ER9X and the Multiprotocol module with no problems. Other than this airplane all other airplanes use Flysky or FrSky receivers. I don’t know if I’m missing a simple step or is this a common problem? The receiver is OK as I have a Jumper T8SG transmitter and it binds ok to this receiver, I will be flying the plane with the Jumper transmitter unless I can ever get it to bind to my TH9X.

I assume by throttle at 0% you mean fully down, which is actually -100%. Spektrum normally use only 80% of the servo pulse width, which is -80% to +80%. It is possible the throttle needs to be at -80% when binding. You may set this by setting up a safety switch on the throttle channel.

With the throttle at 0%, that is the stick all the way down which is -100%. I set the throttle safety switch for -80% value and tried binding with -80% throttle value but still no bind. Thanks for the reply.

Rod, two things:
1) Is the LED on the AR636A flashing rapidly to indicate the receiver is actually in bind mode?
2) Have you tried it with Autobind ON?
The Multimodule firmware has had some changes to DSM protocol recently but unless you have done a firmware upgrade yourself in the last few weeks the settings you have used look correct to me. I will ask Nigel (Daedalus66 on here and RCGroups) to look at this as he is the ErSky and TH9X expert.

Cheers
John

Hi Rod
I’ll have a go at your problem later today. I’ll have to dig out my old Turnigy 9XR, which is my last transmitter running ER9X (others have ERSkyTX).

Thanks for the replies. The led on the AR636A is flashing rapidly. The red led on the multi module flashes for a while after bind is selected then it goes solid. I have tried autobind several times but still no bind. I have not updated the firmware. One other thought I have is, the RF Chip, could it be bad?

Autobind is unlikely to help. It’s intended for protocols which bind automatically when the receiver is powered up.
Channel order should not affect bind. What order are you using with the models that work with this Tc and module?
I do have an AR636 to test with.
What version of ER9X are you using? Mine is a 2015 version that I have to update as it doesn’t recognize a Multi module in serial mode.
What version of Multi firmware does the Protocol in the transmitter display?

Just had a thought.

What model did the AR636A come from? It may make a difference since the AR636 will often only bind when placed in the same orientation as in the model for which it’s programmed. The key issue is which side down? In low wing models, it’s usually label down, while in high wing, its normally label up, except in the Mini Apprentice, where it’s on edge. It’s possible to change the orientation using a cable and special software.

So tell me about the origin of your AR636A. The A tells us it’s for a specific BNF/RTF model.

I should say I don’t have direct experience of this issue, as I use a couple of AR636s, the retail version and they come unprogrammed. But I’ve read of such problems.

You said the Tx and module bound successfully with other models. What receivers are used in those models?

ER9X ver. er9x-r820. The multi module firmware, the multi module label on the shipping box says firmware version 1.2.0. I can't find the multi module firmware version in the transmitter display. The AR636A receiver is in a high wing BNF Timber, the label facing up. I have 4 receivers bound to this transmitter. 1ea Flysky, FS-R9B. 2 ea Flysky, FS-IA6B. 1ea FrSky, V8FR-II.

Regarding the module firmware version, have you done the telemetry mod to the 9X? This is needed to receive data from the module, which includes the firmware version.

I have not done the telemetry mod.

I trying to decide what to try next on my binding problem. If the rf chip is not working I don’t know how to troubleshoot that. If the MPM firmware could be the problem I may try to update it to the latest version. I’m a little uncertain of the procedure for this. I read about the Flash Multi app and installed it on my computer. The app installs the MPM native usb driver and I have done that. When I open the app it is communicating with the MPM and I selected Read and it reads the firmware OK. After that I saved the firmware. At the end of this dialog is the status messages I got when doing this. I haven’t convinced myself to try and Write the latest firmware file using this app. If there is a chance of a fatal error then my bound receivers will all be inop. I’m also a bit confused about the bootloader. I read that if the MPM doesn’t have the bootloader it will need to be installed using a FDTI adapter. I also read that the bootloader is required to enable the native usb port. Since I was able to read the firmware from the MPM using the native usb port does this mean the MPM has a bootloader? Do I need an FTDI to update the firmware? Any help with this would be great.

<< Status message received when reading and saving the MPM firmware using Flash Multi >>

Everything looks correct., just an old version.
