Michael Blakesley Posted February 20, 2019 Share Posted February 20, 2019 Hi I have just purchased a AR636A RX got the Lead and loaded the software BUT I can register the serial number on the web site so I am stuck with V1.4 firmware could one of you kind souls email me the Version 1.43 spmrx.sax file please so I can unlock this receiver Many Thanks Mike Quote Link to comment Share on other sites More sharing options...
BackinBlack Posted February 20, 2019 Share Posted February 20, 2019 Hi Mike, I think you may have to persevere with registering the receiver. I have several AR636 Rxs and had to download a new sprmx file for each one as the files appear to be locked to one serial number. Good Luck Ian Quote Link to comment Share on other sites More sharing options...
Michael Blakesley Posted February 22, 2019 Share Posted February 22, 2019 Well I got my reply from Horizon Hobby regarding my AR636A Hallo Michael this serial number is from a closed AR636 and it can´t be registered or updated. These kind of receivers are special programmed for one model and there is no way to change anything. Reading a earlier Post someone had used a 1.43 sprmx.sax file on a second receiver and it worked so I suspect the locked to serial number issue is TX only There was also early conversation on this link about a version 1.42 SPRMX.SAX file that was freely available and was again not linked to the serial number and unlocked AR363A's no problem again if some kind soul has Ver 1.42 SPRMX.SAX or anyone who has 1.43 SPRMX.SAX and could email it to me I am happy to experiment with the receiver I have and if it fails I will happily report this on this Forum if it works I will be eternally grateful kind regards Mike Quote Link to comment Share on other sites More sharing options...
Bruce Miller 2 Posted February 23, 2019 Share Posted February 23, 2019 PM sent for your email address. Some early ones were definitely 'locked' (like the infamous Sukhoi one) but I have a few more recently that I have been able to reprogram to my tastes despite the hobby shop telling me otherwise. Some are programmed using the ipad app and some with my PC (but not both???). If it isn't going to work - the failure is clear so you will know for sure, then try the other programming method before trying to 'update' to 1.42, and before quitting. Good luck! GENERALLY speaking I have had more respond to the ios APP than the PC programmer. p.s. I have posted my learnings before in this thread and have not changed my views with further experience. Receiver 'updates' are not coded (up to 1.43 anyway!). Transmitter updates ARE and must be generated after registration and login. Let us know, Bruce Quote Link to comment Share on other sites More sharing options...
Kev Griss Posted February 24, 2019 Share Posted February 24, 2019 Hi Michael, I see Bruce has contacted you. If you still need 143 or 142 please let me know your email address and I'll forward them. Regards, Kev Quote Link to comment Share on other sites More sharing options...
Zflyer Posted February 26, 2019 Share Posted February 26, 2019 Flight Mode query Hi folks. I have an ASX 3 rx and all six chanels are in use. ( flaps and u/c). Can i still assign and use a switch for program mode or do i need a spare chanel? Chiz Mick Quote Link to comment Share on other sites More sharing options...
Bruce Miller 2 Posted February 26, 2019 Share Posted February 26, 2019 Yep, you need a spare channel ON YOUR TRANSMITTER but not on the receiver. I have same as you describe with all 6 output channels in use and the receiver can use all 6 output channels but needs 7 INPUT channels to also swap Flight Modes. You can use AUX 1,2 or 3 (if Gear is in use) I have AETRGF from my DX9 doing their usual servo thing on output sockets 1-6 and AUX2 is FM switch using a 7th Tx channel. Works fine. If you only have a 6 channel transmitter then Flight Modes not an option unless you can do without flaps. Quote Link to comment Share on other sites More sharing options...

Graham Laddie Posted June 10, 2019 Share Posted June 10, 2019 I have picked up a AR636a running ver1.1 firmware, I am unable to register and the updater app sees the device as unknown. I have tried editing the serial in the .sax file to no avail. Odd thing is it is identical to my existing AR636A which registered without issue and is programmable. Any ideas?

alec james Posted June 10, 2019 Share Posted June 10, 2019 I also have a AR636A Rx which is working fine but due to a mobile phone problem lost the software so can now no longer alter the settings on it. It would seem that Spektrum no longer offer the same software for Android phones which I have the lead for and as far as I can tell I have to fork out for a USB lead so I can programme this Rx, seems a backward step to me out at the field lugging a lappy about, or have I got the wrong end of the stick. Any comments please? Quote Link to comment Share on other sites More sharing options...
Bruce Miller 2 Posted June 11, 2019 Share Posted June 11, 2019 Alec - Spektrum want you to rush out and buy their bluetooth adaptor: "A Spektrum AS3X Bluetooth Adapter is required for Android device use. Part number SPMBT1000 available at your local hobby shop or HorizonHobby.com The Audio Cable (SPMA3081) or the USB Cable (SPMA3065) No longer functions with the latest version of the Android compatible Spektrum AS3X Programmer App" (From the fine print under Android App on Google Play) So, you are correct that it has been changed and you pick to option you like - Bluetooth Dongle or Lugga-Laptop. Both will cost money! Or ask around if anyone has an abandoned iphone/ipad you can use instead? I would guess that the iphone App will go the same way eventually (if not already - not checked recently, App info blurb doesn't say so). Weird they would make this Android App change for " the next generation Spektrum™ AS3X receivers" when currently only the four usual old variants are listed as compatible...

Stuphedd Posted June 11, 2019 Share Posted June 11, 2019 Hi Bruce and 636a addicts. I have had no luck trying to program my 636Aor 6335 at all, I use the sp3081 from my laptop and my iphone and all I get is "RX communication down " !! I tried to register my RXes and it just comes up with Serial number not recognised ?? I am not sure which of all the numbers on the back of the rxes they want ?? I was trying to register them so that I could "update" them . Has anybody got any clues or examples I can follow ?? and I am NOT a computer genious cheers Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted June 11, 2019 Share Posted June 11, 2019 When the Rx is connected, via the cable To the computer, containing the App The serial number is displayed So, genuine Rx, with lead then displays the serial number To update a receiver using the Spektrum Updater, follow the instructions below: Download Spektrum Updater v1.2.4 and install it. Open Spektrum Updater from the Start Menu or Desktop. Plug the USB programmer cable (SPMA3065) into the computer and plug the cable into the BIND/PROG port of the receiver or the programming port on the transmitter. Power the transmitter or receiver. The serial number of the device should be displayed. Register the receiver on the Spektrum community site. On the community site, click “Download Updates” next to the receiver that you want to update. Click “Updates” under the update to download it. In Spektrum Updater, either click “Choose File…” and choose the downloaded file or drag and drop the downloaded file to the window. Click “Install.” Edited By Denis Watkins on 11/06/2019 08:55:44 Quote Link to comment Share on other sites More sharing options...
Stuphedd Posted June 11, 2019 Share Posted June 11, 2019 Thanks Denis .very easy to understand instructions . My problem appears that I get no response from either of my two Rxes , both of which came out of genuine E flite Planes, from the laptop or I phone . it almost appears that my cable a 3081 is " Faulty " .but I doubt it really . I dont have the USB type cable yet !! Therefore I cannot get past "Start/go" " cheers Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted June 11, 2019 Share Posted June 11, 2019 From previous entry in this post Stu NOTICE: This software is intended for use in open stock AR636 receivers. Do not use in AR636A receivers that came installed in BNF or RTF aircraft or helicopters. So the current update is no good to you, thus there is no point registering your receiver.

Graham Laddie Posted June 11, 2019 Share Posted June 11, 2019 I took one out of an Eflight Valiant, registered without issue, full access to all settings and firmware upgraded. Definitely a AR636A. Quote Link to comment Share on other sites More sharing options...
alec james Posted June 11, 2019 Share Posted June 11, 2019 Bruce...…..Thx for info. as feared I will have to get a USB cable. Not sure if we are really progressing with all this software and high tech bits and bobs but nothing I can say will change that. Quote Link to comment Share on other sites More sharing options...
