I have a jumper t12 pro, r9 2019 module and r9 mini ota receiver. I have already updated the r9 module and the jumper t12 pro to the latest firmware but I can't get the receiver to update! I soldered on wires to the Voltage in, ground, and S port on the receiver and the other end to a plug that fits into the back of the jumper. The lights  on the receiver light up like its working when I power on the transmitter but when I go into the firmware folder on the sd card and try to flash the firmware to the receiver it just tries to reset and gets stuck. Then i get this error message "Fw update error not responding". I'm trying to flash through the s port but nothing I try is working. I also cannot get it to bind but I assume that's because its running a different firmware from the r9 module.
Please somebody help! I'm pulling my hair out!

Unfortunately you cannot use an R9 2019 ACCESS module on the Jumper T12 Pro. You need a Frsky radio with ACCESS. You can read the link below that another member has the same problem. You can still use the module in ACCST mode, but that wasn't the point of you buying this module, I assume you wanted to use ACCESS. This is basically the mess Frsky created. See Snow's rant. Sorry you just basically wasted money on R9 module and receiver. Maybe you can get a refund. Hindsight is 20/20. But if you have the chance, go with Crossfire system. It is much better all around.

You can still be able to use it without any problem. You should just downgrade your firmware back to ACCST and you are good to go.

Valid point. But why buy something for features to handicapped it from the start. It is like buying a new car with all the features and learn you can't use the features you paid for.

You only need to read all the comments under Lee's video below to see that FrSky are sinking fast. The now apparent lack of consumer support for their products probably also goes some way to explaining why it is taking them so long to release their Archer range of receivers. They announced those over 9 months ago and they still only have two receivers from that range released to market.

Shoot, I didn’t realize you can’t use it at all utilizing access. How would I go about just getting it to work because I can’t seem to get anything to work at this point. You’re saying I have to revert the jumper to a previous openTX? Or just try to flash the latest accst to the R9 mini OTA? Sorry I’m still somewhat new to the hobby. What’s the advantage of access over accst? I thought just latency? Will I have more problems with failsafes at long range with accst? Thanks in advance for all the help. This forum seems to be much more active than others I’ve posted to.

The latest ASSCT firmware to the R9M.

I am pretty sure there is a YT video about ASSCT VS ACCESS.

Most features of ACCESS is really not worth it. You will not get better range or a more robust signal.

Yeah,but FrSky explain it on their webstite. It is not FrSky fault. It is customer fault because he didn't read specifications carefully.But, luckily he is able to use it by just using it with changing firmware to ACCST.It is not waste of money because he can use it now with no problem and in the future he can benefit from it more if he decide to upgrade his tx with ACCESS protocol.

Although ACCESS protocol provide good features, nothing is critical for you. You can just use it with ACCST protocol and have fun.

Can you point where this is mentioned in their website? I looked up the R9M 2019 page, and there is no warning or mention of requiring an ACCESS radio.

There is no mention anywhere in the product documentation for the R9M 2019 that you need to have a transmitter with ACCESS capable hardware in it (an ISRM module) in order to make use of the ACCESS protocol with the R9M 2019 module. There isn't even any mention of it in the user manual, which you wouldn't expect to have to read anyway before you purchase a product. The only place you will find this information is in YouTube videos and other articles if you take the time to go looking, and none of these media sources have nothing to do with FrSky.

I may sometimes come across as an FrSky hater on here, which I'm not and I'm a happy owner/user of an FrSky X9D+ ACCST transmitter, but FrSky needs to start being transparent with their customers instead of all these smoke and mirror operations that just seem to be designed to slowly force people to adopt their ACCESS system without them realising until it's too late. Yes, the R9M 2019 module is backward compatible with ACCST, but you need to load old firmware onto it which is no longer actively being developed or enhanced. There is nothing on the FrSky or vendor website at all stating that.

Where it is ?

Yes of course. When you look at this link https://www.frsky-rc.com/product/r9m-2019/, under specifications section it says "compatible with ACCST/ACCESS".Also, under downloads section, there are firmware sections for ACCST AND ACCESS . I accept that message is not very clear,but you can understand it with a quick thinking and searching. But, I admit that information could be more clear.

So I managed to get it to flash the accst firmware like those before mentioned and it bound perfectly fine after that to the r9 module. Another question though; does this mean with my jumper I can still bind to d16 and older? I just can’t bind to anything access protocol right?

The Jumper T16 can bind to pretty much any 2.4GHz receiver on the market because of its multi-protocol 2.4GHz module. This includes FrSky D8 and D16 receivers, but no ACCESS 2.4GHz receivers.

The R9M module is a 900MHz module and can only bind to R9 system receivers. And in your case only ACCST equipped R9 system receivers, nothing ACCESS equipped. The R9M module itself has nothing to do with D16 and it can't bind to D16 receivers.

EDIT: Corrected typo above. 2.5GHz changed to 2.4GHz.
