ExpressLRS Firmware Update Tutorial for SPI Receivers 🎓

[@AlbertKimTV]

*Note* When you paste back in your old diff into the CLI, it may cause the filters and pid sliders to stop working. As some have pointed out in the video this is what happened on my Happymodel board. It didn't seem to happen on the BETAFPV board. It would be best to not paste back in the whole diff but just the non-filter and pid settings and readjust your filters and pids manually.

Even though this is RC1, it seems the build is still not stable. I guess that's why it's stored under "unstable" releases?

[@PkwyDrive13]

It doesn't cause sliders to not work... Above the sliders there's a drop-down that says OFF, you just change that too RP or RPY

[@shepdawg66]

Saved me. I was just about to revert my module back to 1.x so I can fly the whoop I'm building with the BetaFPV board. Thanks Albert!

[@Michael_D_show]

Thank you so much for this video. I had just received my HappyModel ES24TX TX module for the Jumper T-lite and the BetaFPV Meteor65 Pro. This is my introduction to ELRS and the first thing I did after installing the TX Module was update to the latest version of ELRS and could not get the Meteor65 to bind. I wasn't sure what version of Betalight to flash to the Meteor65, so it would work with ELRS 2.0.1 and had spent a large portion of yesterday trying to figure out what to do. I was ready to just flash my TX module back to 1.2.1. Also, thank you for the 411 about changing the PID Loop Frequency to 2kHz. Thank you again.

Thanks Albert. You saved me from jumping through so many hoops with this meteor 85 that I just got not realizing that it was version two I was able to buy a module and downgraded to version two, and then your help with the binding for a situation, made it a hell of a lot easier I’m new to ELRS and this helped a lot!

Looks like pasting back the old diff carries over some strange settings that might cause problems. Looks like I'll have to make an update to this video later when the final release comes out. 😔

Damn it is was looking all over beta fpv support website and could not find the update for v2 spi elrs. Thanks for making the video.

[@Rc_impulse]

I broke the ceramic antenna on my meteor65 aio elrs the one which was bound to break if canopy changed. There are four pads which one and what do I solder to replace the ceramic tower. Length 30-33 mm I believe but shielded or Co ax or just a naked wire Thanks Albert for all your help

[@AlbertKimTV]

Three of the pads are connected to ground so use your multimeter in to test the pads against ground and there will be one that isn't. That's the signal pad.

[@Idontdohandles]

Just look under the board --- only yhe pad that connects to the1 antenna carries thru a hole to the underneath side of the board. This happens to me all the time if you catch it before it burns up the fc I have successfully soldered in a 12.7mm wire and got decent range still. They do tend to start failing though after the *plastic/copper antenna are busted off. Presumably if that's getting busted off then your whoop board is exposed and you are bashing on more than just the antenna on the board. I tear thru these dam things like water lately they are horrible on reliability weather it be HAPPY Model or BetaFpv. But hey, gotta have the ELRS range!

[@frankcastillo8869]

Thanks for the video, but RC1 is still unstable and I've had random failsafes with this build so people may want to wait until more bugs are worked out.

[@AlbertKimTV]

Yes, this is an "unstable" release. Thank you captain obvious! 🤣

[@FireChicken747]

I own a meteor 65 the upgraded 2022 version and is has a SPI ExpressLRS 2.4G receiver attached (not built in) and I wanted to ask someone this because there is a hard red wire connected to the flight controller ( not the receiver) and I wanted to know if that connected to the receiver and it broke off or it does not connect to the receiver and just the flight controller because like at 100ft it says rtf lost and it is a lot less then this inside a house so I would really like to know if that is the problem

[@sebcbien263]

Hi Albert ! thank for your work ! For the 60% CPU, you should not worry about, the betaflight devs said that they changed the way it is calculated and it is now more precise (an higher for the same cpu load). I have the exact same board and I fly it at 4kHz without problem

[@AlbertKimTV]

At 8Khz, my transmitter would not connect.

[@frankcastillo8869]

4khz didn't work for me. I had to go down to 2khz to get a stable connection.

[@turboed13b]

I've been telling them it isn't fine. It wont connect at 60%. Overclocking cpu cause s other problems. I can either fly no rpm filter at dshot300/4k or fly rpm filter with dshot150/2k. I rather stay on elrs 1.0 for now.

[@albertocagnin2108]

Thank's for this video, if i have 2.5 version on tx module will it bind to those crazybee or beta elrs with 2.0 ? In can not found a sure answer .

[@AlbertKimTV]

All V2.x versions of ELRS are compatible with each other. However, older 2.x versions may have bugs in them.

Oh man. This is great!! I'm waiting on the crux35 in the mail and I'm sure I'm going to have to update the FC. Thanks man. Same exact FC and everything. I was scared of flashing. Now I'm more confident with your video 😁👍

Still back up your settings but don't use them on the RC1 build. Seems some old settings causes problems so start from scratch and put in your settings manually.

Can you use the new firmware also for the Betafpv 1s 12a elrs V1.0 board or only for the V2.0?

The V1 board doesn't have an SPI receiver. It's a full receiver built into the board. So this video doesn't apply to the V1 board.

Now that BF configurator 10.7.2 is out, can one use that configurator instead of the 10.8 to do this? it shows BF 4.3 RC2 on the flash page.

Hi Albert question about express lrs and a Darwin whoop board. When I power up my tx and the Dawrwin whoop board it takes about 30 seconds to link up. Is this a firmware issue?

Power up the TX first. If you power up the TX second it normally takes 30 seconds to connect. Make sure the packet rate is the same on both.

The FC isn't actually in DFU mode. I think that's a bug in the configurator. It shows as in DFU mode, but it's not. You have to manually trigger DFU mode via the bootloader button on the FC and restart the flash and it will work.

[@guambra2001]

Forgive my noob-ness, but if I’m understanding correctly, you need to have BF 4.3 in order to fly with ELRS 2.0 on the AIO boards?

[@AlbertKimTV]

Yes, that's correct. The 4.3-RC1 build has ELRS V2 baked into it for the AIO boards with SPI receivers.

[@frankcastillo8869]

By the way guys, don't bother with RPM filter on RC1. It doesn't work yet.

[@AlbertKimTV]

It should if you set the 2khz pid loop and Dshot300. Won't work on Dshot600. Also some versions of ESC firmware are incompatible. Someone should make a database on all the compatibility problems. I'm sure no one will donate to that cause.

[@PkwyDrive13]

Betaflight 4.3 just seems to be harder on the CPU load.. My nazgul 5 V2 with f722 on BF 4.2.10 with 8k/8k only ran 5-10% CPU load.. Same settings on 4.3 it runs 45-55%.

Can I walk back the new ELRS V2.0 board just like you did here but in reverse? IE want to make the new mob7 bind to my old school ELRS tx that binds to the V1's.

Flew 4350ft distance from home in a 3.5 mile round trip! It's my longest flight to date and had one flash warnng of link quality got rssi all the way down to minus 102 dbi (signal loss is minus 107ish i think) and just 20% link quality on the 500mhz packet rate using 250mw elrs power and my video went out on me using an O.R.C Shield 2.5dbi antenna and 6.5 dbi halo rhcp's on the other side of EVO300D Dual diversity goggles.... I gps rescued - it worked immaculately and ascended up to where I got my video back pretty quickly and was able to take control back and fly another 3-4mins home. I'm not much of a video KZbinr but maybe I'll actually process and post the footage.... nothing major for the experts but for a novice like me it really felt like an accomplishment. It's only my 2nd long range flight ever using gps and flywoo lr4 --- I'm used to smaller stuff 3inch toothpick is big for me lol! Thanks for all your great vids they do certainly help and maybe even more so they inspire me!!! As far as link quality - prolly a combo of me using the 500 packet rate + a VAS rx antenna set on "Omni-Directoinal" (I forgot to flip it to "Long Range" before taking off). 😳 🙏🌋🏅

[@Idontdohandles]

As for v1 and v2.... I still love v1 and am.happy on it and don't have issues to complain of the way I lost frskys' and whatnot on d8 or d16. Got to be a way to back up a V2 to V1 and I have it sitting here so tomorrow I might see if the firmware is there to do it to a V2. I'll dump all ahead of time just in case have to go back. And flash can go back usually, no? Or you think it's a really bad idea? But in the end your right V2 the way to go as they are discontinuing V1 boards :( I think. I'm still on last year's Betaflight like 10.7 or something --- just like to fly not continually flash and update!

[@Idontdohandles]

skip that! The new ELRS Mob7 V2 comes with X12 5-1 AIO does not look like any release candidates for that board, let alone one taking back to a V1 that probably doesn't exist on BF. I'm swapping in an EP1 on UART1 and will flash back to my firmware V1 -- that should fly it good enough - adds a gram of weight :( but this is for bashing only really -- i have cut down lightweight versions in 65mm at 14.8g and 75mm at 17.5g ---- those whoops whoop it! ;) Also almost washed that extra weight by swapping to all plastic screws throughout the bird -- but then i added 1.2g RCHP antenna so boom the *nasty gram is back again ;P
