Hi Mike, last erskytx and mutimodule version flashed. It works, problem has been fixed, now I can select the subprotocol without any problem. I still can see what you said about the name in the module and also in erskytx and it updating. For example with Devo protocol, when selecting the subprotocol...

Update posted. Are you only using the multi-protocol module or are you also using a FrSky Tx module? If you go to the download page for the XM receiver, at the bottom is: "History firmware DOWNLOAD (not compatible with v2.x.x)". Click on that and you will get the V1 firmware for the XM Rx...

Big thanks, Mike. I will update the erskytx as soon as you publish it. I have updated my modules today and I have just seen there is a newer version today, so will update that too, lol. Interesting that file you linked, thank you! I have been reading a lot about those tiny frsky receivers... So far ...

Oh I see. I thought I screwed something. But I guess all of that means you will fix it at some point, right? I updated everything because I needed a 16ch receiver and I got a frsky XM, but I did not know there were 15 usable channels and a 16th for rssi. After googling for a while I found if I updat...

Hi guys, I am having an issue with it. I asked it in RC groups, Ill copy paste the info here: "Hi guys, I have an issue. Radio is a 9x with a 9xtreme. Radio software: erskyTxR223A9.zip 20-Jan-2021 21:57 I updated the external multi module (Irange4x) with the 1.3.2.6 version And the internal mod...

Ok, I took a pic of the internals, hope it brings somebody info...

Ok, I got it and... I cannot bind it, lol.
I tested flysky protocol, and AFHDS 2A and there is no way... Any ideas?

Ok, I answer myself. I've found the specs of that receiver and it is indeed flysky compatible. I ordered it, so if it not works I will report back, lol.

Hi friends, I have just seen this: https://www.aliexpress.com/item/4000411589058.html?spm=a2g0o.cart.0.0.45ac3c00ovnDpy&mp=1 A 16 ch receiver that I can well use in one of my toys. Do you know if it is compatible with the multi module? I think (but I might be wrong) that the HG radios work with ...

Did you find a direct replacement? João Surprisingly I had one at home that fitted almost like a glove. It needed like a 1mm of sanding in the top plastic part of the switch, to be able to fit the cap, but besides that, it fitted great and works. My main radio is that 9xtreme you already know, this...

Ok, I replaced the switch and now it works.

Awesome forum, full of info.

Hi, it seems I am having the same issue here. Time to open the radio, I guess...

It looks like I did a change to allow an extra switch to be converted to 3-position, and this has upset the detection of PB1 and PB2. I've just posted a test version, for the '128, that should fix this. I don't have a '128 radio any more, but I found my '2561 wasn't detecting PB1 and PB2, but with ...

I attached pics of the provisional setup. Buttons are not installed yet

The buttons are round on/off buttons, not self springed, if it helps.

What voltages do you see on pin 43?

Mike

I see 4,80v

Check that without the switch pressed you have 5V between the switch connections (one is ground and the other should be pulled up by a resistor internal to the processor). If you don't see 5V, check the ground connection really is ground (perhaps measure the voltage on both sides of the switch to a...

Hi Mike, this time I need to add two buttons in the back of the radio. On-off buttons. How should I add them? So far I soldered a wire to the pin processor 35 and 43, as stated above, to one of the legs of that switch, and the other leg to ground (to the back of the radio) In the hardware menu I sel...

Thanks Mike, I installed the app and it works.

That will fix the issue if it happens again.

Suggest, maybe it could be a hardware problem. If you have a bad switch or a bad chip it could be causing the troubles. Many years ago I had a new 9x that bricked when programing it and later found the selecting switches were corroded. After replacing several of the selecting switches, it worked OK...

Oh, I see.. :) But if the radio is completely dead, I don't know if maintenance mode will work. As far as I know it is part of the firmware :) But Mike knows better than me of course.. :) João Yep, that is the thing, bootloader and maintenance mode worked fine. Some posts above I uploaded my faulty...

I have just checked on my 9xtreme radio. You do have a "Restore" option in the Radio "Settings / EEPROM" menu. You can use it to restore the EEprom you have saved to the SD Card. João Yes, but that is when the radio is working, not like the other days with the radio completelly ...

I think you can :) but not sure. I know we can backup the complete eeprom to the SD Card. I don't have the radio with me at the moment, but you can check in the Radio Settings/EEprom. You might have to unlock the menu by holding the left horizontal trim to the left at power ON. :) João Hi Joao, yes...

Hi Mike, I flashed the last test version and seems to be working OK. I will report if I see some issues, hope this version is the definitive one so I dont have to annoy you more, lol. The issue that I had yesterday was a real pain, because the radio was unusable until I connected to the PC, so if in...

Thanks Mike, I will test it tomorrow morning, first thing I will do.

This time I did not get the bad eeprom message but just got that full black screen. Not sure if you can see anything in the files I posted.

Thanks again, will post tomorrow

I have been thinking about this and I have some ideas: Blocking access to the encoder removed most of the issues... Maybe you could block it until the splash screen is gone. Also another thing that would help a lot is to be able to restore the eeprom from the bootloader or from the maintenance mode....

Hi Mike, I believe I am still having some issues with this. It is not the first time the radio does not start and I had to replace the eeprom with eepe. Today it happened again, but thanks to God I did a copy of the eeprom two days ago. I tried to start the radio and I had the starting music. Even w...

João

Correct! Thanks for the aclaration.

Thanks for the help, guys, very appreciated.

In this case the SMD button is broken. He opened the radio and checked inside and it does not do any click... So it needs replacing.

Just to point the button was damaged in shipping. It does not make the characteristic "click" when pressed anymore, and he has to press it very hard to make it work, so it looks like it needs to be replaced. Unfortunately I dont have more 9x radios so far except my extreme so I cannot meas...
