Easiest Way To Flash and Bind ExpressLRS! 

im glad im not the only one actually following both n still 100% stuck - i love the guy too but this is the 3rd Bardwell video that 0% works - did u ever get this to work if so how??

Yeah I got it figuered out for the most part how about you?Do you need some help?@@Simply6FPV

Lol

Hahaha

Hold my beer, Happymodel baseline 6 months in!

I am learning to new to this new hobby and Joshua you been really helpful. All of you guys and FPV community have been great, anyways still can't bind my Mobula 8 to my Elrs boxer. Right now, I can only connect to betaflight through virtual option and can't access my presets I think I lost it because I can see it when I try to ready the codes through my pc.

Damn you devs, always fixing things right after I document the bug. FWIW I still would set bind by webui over flashing, if I had the correct version.

@@JoshuaBardwell and this is EXACTLY why I dont mess with elrs. if I blink I am out of date. Xfire just works. a how to bind a Xfire RX video would be 34 seconds.

English ?

I really wanna love ELRS. I really really do. Took me a day for my spi whoop to flash and bind. I have 2 more built but grounded till I can recreate that winning lotto combo. Then there is agent X, M, and FU, I just wanna fly. Wish I could plug the quad into the radio, run a lua from radio to flash and bind all in one go.

@@muchthump IRC Ghost is easier than that 👻

Correct.

Same here. Very satisfactory experience

I got 3 elrs nano and mico modules and 9 rx's . One worked until jb weld doesnt stick the tee antenna to carbon fiber and it shredded in the props . Could not fix the ufl connector . All nine said factory firmware matched but doesnt . Buy a computer and cable anyone ? I learned my lesson . Chasing a more and more expensive carrot no sir every week upgrade videos

Correct. But I"m not flashing through USB/UART, I'm flashing through WiFi.

Enable the "force flash" option.

If you raise the wifi hotspot timeout, you can extend the time before wifi kicks in to like 10 minutes or some other very long value. But using wifi to configure the system will become difficult since the RX will need to be told to go into wifi mode manually. If you don't have your controller, you'll be waiting a long time.

Yes that's fine.

I never add filler content to manipulate length and run mid-rolls. My videos are as long as they are. And anyway, the cutoff is 8 minutes not 10 minutes, so do with that whatever you want. From the tone of your message, it sounds like you like Crossfire and are not sincerely interested in the things that ELRS brings to the table. Dont' bother trying ELRS would be my advice. It will be a waste of your time, and will just self-reinforce the things you already believe. In case you are curious, the reason ELRS doesn't have over-the-air firmware update like Crossfire is because ELRS is supported by many different manufacturers. Because there are so many different firmware targets, they can't all be stored on the module and automatically flashed at bind time. The tradeoff here is that you can always find ELRS in stock, and there is cross-vendor competition for features, build quality, and price.

@@JoshuaBardwell I am interested in the penetration ELRS is said to have over Crossfire. You have to admit with ELRS there is a lot more you have to go through to set it up and especially your first time setting up the TX as well. I kind of look at it the same way as I look at KISS Ultra. A completely different and seemingly more complicated animal than Betaflight. Your opinion on both has me decided that I will try both in the near future but the set-up process on both is what's holding me back. I rarely have any range issue with my Crossfire and I'm not a long-range guy anyway. I'm interested in if the penetration with ELRS is that much better than Crossfire? Is the juice worth the squeeze? 👍

If you're using 2.4 GHz ELRS, compared to 900 MHz Crossfire, then which one has more range is difficult to predict. Crossfire's lower frequency will tend to give it longer range, and I suspect it would win at 50 Hz, but lose at 150 Hz, since 150 Hz CRSF doesn't use LoRa. If you're comparing 900 MHz ELRS to 900 MHz Crossfire, then ELRS will give better range. When both are operating at 50 Hz, ELRS will give somewhat better range because it has a smaller, more efficient packet format. This allows it to use a lower bit-rate modulation that has better sensitivity. ELRS 900 MHz can also run at 25 Hz, which would further increase its range advantage. CRSF 900 MHz can only use LoRa at 50 Hz packet rate. At 150 Hz, it uses FSK modulation, which has significantly shorter range. ELRS 900 MHz can go up to 200 Hz packet rate using LoRa. At 200 Hz, ELRS 900 MHz may have less range than CRSF at 50 Hz, but CRSF doesn't even offer this option, so it's worth calling out. In general, I would not expect ELRS to have enough of a range advantage compared to CRSF, to make it worth switching, as long as you are okay with the 50 Hz packet rate. If you want lower latency than the 50 Hz packet rate offers, then ELRS is worth switching to.

@@JoshuaBardwell what about penetration in your opinion? I park freestyle (trees interference) and some bando/around buildings freestyle (concrete interference). How would you say the penetration compares between Crossfire and ELRS? While I have you in the comments I also am curious to know if I can get better range and pentration with my 03 air unit. I have Integras in fcc mode and lose video at lower altitude long before a lose my link quality.

Penetration and range are the same thing: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nb0a9YORAks.html

You can decide how you want to do that, but typically all your RX would have the same binding phrase.

Yes, as long as the ELRS RX is UART-based not SPI-based.

Either .bin file works, even of you rename them :)

They're identical. It doesn't matter. I don't know why there are 2 of them.

😧

You are joking everyone . He is joking .

@@gregorydahlwell maybe not. In order to flash an frsky r-xsr, you have to use a tiny adapter (if you have a connecter on your receiver, otherwise you need to solder wires) and then you need to plug that adapter into your radio JR bay and make sure that the wiribg is correct. Then you need to put the firmware on your radio in order to flash your receiver. And I don’t even then mention the whole access/accst v1/v2 eu/us mess for the firmware file. ELRS is so much easier

For me frsky is easier. Bar none . 👍

Push button on reciever to go into bind mode, push button on radio to bind, boom...go fly. I have never updated a frsky reciever. If it flies, why mess with something that works great. I am very reluctantly trying elrs. Only because I can't find the micro recievers I like. I would rather fly more than sit in front of the computer more.

Good point. Here's a link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2kcRi1cHejM.html&ab_channel=JoshuaBardwell

All the same.

If Mob6 has SPI receiver, then it doesn't do WiFi. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-G1dK7nk5Ds4.html

@@JoshuaBardwell thanks Joshua. ⭐️⭐️⭐️. Really appreciate all your hard work!

My problem with that is the RX wifi is very short range so it can't always reliably connect to my wifi. It it can always connect to my phone which is right nearby.

@@JoshuaBardwell Ah, this is true. My access point is only about 4-5 feet away from where I do my configuration, so it connects without issue. The PCB antenna on most of these boards just doesn't cut it for anything beyond the room its in.

I was about to say the same thing. Then the build and flash button works without any issues

They are identical, just one is named more descriptive. You can pick either one. It doesn't matter.

@@JoshuaBardwell Awesome. Thanks so much. You’re a big help and the reason I can maintain my sanity in this sometimes confusing hobby. I’m joining your patreon now.

There is a video about SPI receivers linked in the video description.

Most of the time this means your FC has an SPI-based receiver that doesn't do wifi. For mroe: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-G1dK7nk5Ds4.html

@@JoshuaBardwell Got it thanks

What model receiver is it?

@@JoshuaBardwell Built-in Receiver: Serial ExpressLRS 2.4G / Frsky SPI from the Brushless betaFPV f41s5a flight controller. It's built in ExpressLRS and also a built in ExpressLRS transmitter, the literadio 2 se. I can connect FC to betaflight and transmitter to its respective software, but I can't get the transmitter inputs to show up in betaflight. Help pls

Betaflight defines two types of receiver: SPI and serial. You can debate the correctness of these semantics, but when you get around to configuring your flight controller, those semantics don't matter.

Got the idea, thanks for the clarification. Learnt something today ;)

Pick up here and keep moving forward with your setup. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EDnQEep2X4I.html

These instructions don't work with SPI elrs rx. But many aio have serial rx.

@JoshuaBardwell it's a pavo20 elrs version but I couldn't get into betaflight one day so I flashed it but now I can't find elrs on the receiver tab, pretty much everything else there tho

@JoshuaBardwell tried to do a cli dump from betafpv but don't think it worked 🤔 lol I definitely could use some help later today or tomorrow!

I finally figured it out lol all i had to do was watvh until roughly half way and bam, it hit me what i needed to do in betaflight lol​@JoshuaBardwell

​@@JoshuaBardwellnow I have to get the elrs module for my taranis qx7 I got for a steal today! He gave it to me! Definitely helps me big time!
