Multiprotocol Module: Tips,Tricks and Common Questions

[@IanF-FPV]

The Wiki and the thread on Rcgroups was most helpful for me too Lee. The recent fw for the Multi module has Skyartec's protocol however the OpenTx fw for my FlySky Nirvana has it's Multi module code from OpenTx 2.2 which only allows 63 protocols when Skyartec is 68. Wiki and the group walked me through how to change the code and recompile so I could flash it to my module. Worked like a charm.

[@paulg5437]

Excellent explanation of the MPM tech. I've often noticed that binding with the MPM module fails if the receiver is too close (e.g. Spektrum) so moving it 2-3 meters away usually fixed that.

[@Transit67F2]

Just bought one of these. Thankyou for the excellent presentation !

[@swissfreek]

I only recently found multi-module.org earlier this week and I can’t believe there was so much I could do and didn’t know it. Very helpful resource.

[@frankbarajas]

Thank you Lee for producing such a much needed resource for all of us. You simply made my day today, by solving a vexing problem that had me just about to give up.

[@wrstew1272]

Lee- you are so conversant in electronic jargon Is It possible that you were an electronic engineer in a former lifetime? You really explain the workings in a professional manner! Many thanks

[@TeamYankee2]

Thanks for making these videos... totally new to this and bought the TX16s as my first radio... so far setup the X8R with SBUS/smartport telemetry via a F722-SE flight controller.. . so far so good! Couldn't' have done it without you!

[@jimsnodgrass8454]

Hi Lee, Wow, what a terrific video.. this one really knocked it out of the park for me, since I use both the internal and external DIY 4in1 Multi-protocol (MPM) modules in My transmitter exclusively. I think what Pascal and the 4in1 software developers have done is miraculous. No other OpenTx group has come close to providing such an incredible array of capabilities and done it in a truly opensource way that allows you to review the comments and tweak the 20,000 lines of source code and refine it further if you really need to do so. I hadn’t known about a couple of the latest new functions either, so I’m very happy you’ve touched on them here.. but I do have one important question for you.. Yes it’s true there is a detailed list of all the protocols that are currently supported up on the github web site you referenced at least three times.. but here’s the problem.. and this is only a problem for many of us with the cheaper toy planes, boats, Quads and RC Cars and we bought all this stuff and the cheap crappy transmitters that come with them.. when we’d like to use our new MPM Transmitter with these models too.... however I’d venture to say at least 90% of us haven’t a clue what RF protocol is in the models Receiver because that’s rarely advertised. So here’s the question, does anyone have a website yet that shows a detailed photo of each one.. (Yes, I know there are several hundreds of these that have come out of China) with a column alongside each photo that tells you what protocol by (name or index number) is actually in it ? As you mention, you need that info to bind it and control it. Most of us have this problem on the older heli, quad, and other RC toys, we’ve got but find it’s nearly impossible to know which of the 80? or more possible MPM protocols we should try to use. The supported list is WAY too long to try them all.. Fact is I believe some aren’t supported yet, and many never will be, unless MPM decides to add an IR ( Infared) transceiver option. Anyway, really great video .. thanks Again for your time and effort in putting the custom graphics, and all this key content together in such a clear and concise way.. I Love it !

[@nadrojgansi1345]

Hi. I just ordered an Irangex IRX4+ multiprotocol module only to find out once again that the processor is now an ARM-M. Kindly point what firmware should I use for use with EdgeTX. My radio is a Radiomaster TX12 MK2 elrs version. Thank you in advance!

[@onionhead1308]

I have the Taranis x9lite, I'm looking for an MPM that will connect with the Eachine P51 Mini Mustang (V761-1 protocol). I got the XJT lite module, but that only seems to work with ACCESS; I can select from items under the 'multi' menu but the module does not power on. The module works great with the ACCESS choices, so either there is a trick I don't know or I need different gear. I'm considering a Taranis X9D Plus SE (for many reasons) -- what MPM would I need for that tx to work with the V761-1 protocol? to be clear -- two separate questions: What MPM will allow me to use V761-1 protocol with the Taranis x9lite ? What MPM (or other solution, idk) will allow me to use the V761-1 protocol with the Taranis X9D Plus SE ? I am assuming that if I get V761 i will have the ability to use all of the other protocols I see listed for MPM, is this correct? and a big thanx for all the Painless360 work!

[@Painless360]

The Jumper 4in1 is a common choice. Best of luck

[@BornIIfly]

Hi Painless360, I got a really dumb question, what are the markings on the gimbals called? I'm using the x-lite pro & there are no markings, I can notice stick postioning. I noticed on the x-lite pro, from the middle stick position to the far left or right is a lot shorter than it seems. On larger controllers it's more wider of course. Between thumb & pinching is the accuracy, I'm fly with thumbs & to change (let's say) the speed by one point is easier & precise with pinching than thumbs. I know it's just one point, but any pilot would know one point is enough to change the flight of thhe drone. Many thnx & take care

[@Painless360]

You know, I'm not sure what those graduations are called officially! Smaller radios often use smaller gimbals with less travel to support the smaller size. The sticks are often height adjustable that can help but will not make up for the smaller movement in degrees. The feel of a radio is a very personal thing, just as in pinchers vs. thumbers. Radios that have the gimbals nearer to the sides of the radio are often considered better for pinching.. Happy flying!

At 2:40 you tell you can see the channel order of the module by going into model setup. However when I try to do this on my Taranis with 4-1 from banggood "module status" only reports "No MULT_TELEMETRY"

I have updated my multi protocol module and then updated my FrSky Receivers (XM+ and RX8R Pro). I now can't get a bind on either Rx. The FrSky download page says I have to update the firmware of radios, RF modules and receivers. Is there a particular multi module firmware that corresponds to the latest ACCST D16 v2.1.0 Rx update? If so, where do I find it?

[@nwm972]

hello, I have a tx16s transmitter and I was lucky enough to buy a plane with a futaba r6106hf receiver, there is an option for multi/futaba in the settings, but I can't connect it, is this even possible? I would like to ask for your advice. Thank you!

[@Painless360]

I don't use Futaba here so am not aware of the nuances. kzbin.info/www/bejne/epeuqqtmrrmVjrc may help... Happy flying

[@PFinkoloTL87]

Thank your for the great info. Do you have an info or an estimate on the range on the Jumper and/or Hobby Porter 4in1? I've read that the iRangeX is stated to give around 240 m. I'd like an MPM but decent range would be good.

[@Painless360]

Range is very subjective. Antenna tuning, alignment, fine tuning, antenna position, local RF noise, quality of components, power levels and many other things affect it. Not all of the 4in1 chips output the same power either.. I have a video in the MPM series that looks at this... Best of luck

[@PFinkoloTL87]

@@Painless360 Thanks for pointing out your video. I watched it. I read on aliexpress, that the iRangeX developers have tested the CYRF6936 on the (tiny) Blade mcpx and similar Walkera Super CP helis, which have very short antennas. Due to their size I doubt they have full range receiver systems. Range on these two helis is stated at 200 m ("Tested Ground Control Distance"). I'd use the iRangeX or rather the JP4in1 on my Blade 230 heli, which is equipped with the Spektrum AR636 full range receiver. I am looking for an estimate on how the range would be. 200 m is not enough, no room for reserve. I of course don't need half a kilometre for a small heli, but 200 doesn't feel right. Both the CYR-chip in the JP4in1 and in my Spektrum tx have a power output of 100 mW. So range, after fine tuning and antenna alignment as well as flying at the same flying field should result in roughly the same range, shouldn't it?

[@Painless360]

Assuming the unit you receive has the same spec and firmware and the local flying area has the same RF noise, yes it should. Happy flying!

Hi, I'm really new to my Radiomaster TX16S. I don't have a external Module but would like to connect to a Spektrum transmitter for buddying. I would like the Radiomaster to be the master and the spektrum to be the slave. So my question is do I need an external module and if so which one would be correct to connect to a Spektrum if this is possible to do. TIA.

Hope you can help me. I have the Radiomaster TX12 mkii with the cc2500 mpm module. Went to update from the mpm site but there were 2 .bin listed, a 64kb and a normal one, and I didn't know which to use. I instead had EdgeTX Companion download all updates for it but I think it actually downloaded for a 4in1 module. Flashing it seems to have bricked my mpm, because now it says "no telemetry" where the version number should be, and trying to reflash with any other .bin it fails saying "FW update error device not responding" Any help would be appreciated.

[@Painless360]

After watching your vid on the Radiomaster I went and bought one,silly question but scrolling thru the recieves I can bind to as I have used assan for years got those working but purchased a second hand Align M25 mini drone it came with a Futaba Fast receiver in it thought nice will bind to that but scrolling thru Futaba is not there so does the Radiomaster not cover any Futaba receivers

Thanks for the video. Have bound a spektrum receiver to MPM module in the back of my X9d and notice that there is no failsafe option to set.

Its just dangerous not having a failsafe function. Can you help?

I have a Radiomaster TX16s that is great, for one exception. I have searched and searched, and no one can inform me on how to identify which protocol my (toy grade) receivers use. I have several popular toy grade RC's, including a Sharper Image and UDIRC drone, and a New Bright truck RX that I want to re-purpose for a home made camera gimball. I have contacted the MFG's to no avail. I am disabled and on a very tight budget, so I invested in this radio thinking I could use it for anything PPM compatible forward. I'm shure this TX is capable of doing what I need, but without knowing how to identify what protocol these diverse toy grade Receivers use (which this TX is advertised as supporting) I am unable to utilize it for my intended purpose. I appreciate any assistance. Thank you.

@@Painless360 the mpm module has its own firmware on it from multi module.org.
