currently strugglng with first setup binding radio to rx
bought a happymodel moblite7 elrs (spi)
bought a radiomaster zorro elrs
flashed the zorro to latest firmware with elrs configurator
updated the moblite with betaflight latest version, which i believe updates rx firmware
i am unable to get the two to bind. i click bind in betaflight, red light on moblite goes from slow flash to fast indicating its in bind mode? when i use lua on zorro to bind, nothing changes.
please, any help out there for a frustrated nub? ![[-]](https://intofpv.com/images/collapse.png) • Posts: 21,296 Threads: 589 Likes Received: 8,982 in 6,647 posts Likes Given: 1,426 Joined: Jun 2018 Reputation: 789 What version of Betaflight is running on the Moblite7? If it has Betaflight 4.3.x installed on it, that version utilises ExpressLRS 2.x so you will therefore also need to make sure ExpressLRS 2.x is flashed to your Zorro. ELRS 3.x isn't compatible with ELRS 2.x. Both the receiver and transmitter need to be on the same major version of ExpressLRS. If you desperately want to run ExpressLRS 3.x on both the Zorro and the Moblite7 then you can upgrade the Moblite7 to the latest release candidate of Betaflight 4.4 (see HERE) which utilises ELRS 3.x, but just keep in mind that release candidates of Betaflight are not final versions and they still have bugs in that could result in unexpected results while flying. • Posts: 1,506 Threads: 49 Likes Received: 714 in 525 posts Likes Given: 478 Joined: Oct 2020 Reputation: 93 HappyModel also has a custom build of Betaflight 4.3.1 compiled with ELRS v3 SPI support.

https://www.happymodel.cn/index.php/2022...-download/ thankyou. could you explain 'save a diff' please? cheers • Posts: 21,296 Threads: 589 Likes Received: 8,982 in 6,647 posts Likes Given: 1,426 Joined: Jun 2018 Reputation: 789 Run the "diff all" command in the Betaflight Configurator CLI tab and save the output to a file using the "Save" button. This will save a copy of your current factory configuration. After you have flashed the custom version of the 4.3.1 firmware, load the saved "diff all" file back into the CLI to restore the saved factory configuration. • Posts: 1,506 Threads: 49 Likes Received: 714 in 525 posts Likes Given: 478 Joined: Oct 2020 Reputation: 93 30-Dec-2022, 12:09 AM (This post was last modified: 30-Dec-2022, 12:14 AM by V-22.)

the moblite7 is on 4.3.2
i flashed the zorro with 3.1.2
soo, you might have found my issue...
i'm happy to try the betaflight version you linked to... im not desperate to have them on 3.x, just want to get the thing in the air. would it be better to try and downgade the zorro? Betaflight 4.3.2 has a bug that breaks ELRS SPI receivers. Use 4.3.1 or 4.4.0-RC2. https://github.com/betaflight/betaflight/issues/12033 • Posts: 45 Threads: 9 Likes Received: 8 in 8 posts Likes Given: 3 Joined: Dec 2022 Reputation: 0 ok, so i deleted betaflight, installed configurator 10.9.0
updated firmware, we are now on 4.3.2 btfl
red light is now solid, when connected via usb, indicating bind?
in reciever tab, there is now no option to bind. i see no stick inputs...
im all lost again i'm afraid... • Posts: 45 Threads: 9 Likes Received: 8 in 8 posts Likes Given: 3 Joined: Dec 2022 Reputation: 0 (30-Dec-2022, 12:09 AM)V-22 Wrote: Betaflight 4.3.2 has a bug that breaks ELRS SPI receivers. Use 4.3.1 or 4.4.0-RC2.
https://github.com/betaflight/betaflight/issues/12033 OK, so flashed moblite again with 4.3.1 im back to where i was, rapid flashing light and no bind  • Posts: 45 Threads: 9 Likes Received: 8 in 8 posts Likes Given: 3 Joined: Dec 2022 Reputation: 0 bingo, sorted. went and left it for a bit, came back and tried once more before bed. bound, i can see controller movements in betaflight, that's good enough for now. i will start again in the morning. many, many thanks for your help, what a curve it is eh?   • Posts: 2,501 Threads: 76 Likes Received: 1,385 in 1,036 posts Likes Given: 804 Joined: Apr 2022 Reputation: 41 Use a bind phrase. Don't manually bind. Setup a bind phrase on the Zorro and for every quad you buy or build you just need to ensure the bind phrase is the same. ELRS does the rest for your automagically.
