ExpressLRS How-To Build Experimental Firmware Including SBUS

[@williamcox3852]

This ELRS technology is fascinating. Something new being developed for this rc hobby. Great job John.

[@RCVideoReviews]

It's like an RC playground out there.

Thank you, Thank you, I'm sure you go a lot of requests to build for different rx's. I had a 24d but went out and bought a few spare EP2's to use the bins you provided, this is better.

[@RCVideoReviews]

When I first learned how to do this, I followed directions for install of the entire toolchain. I figured out afterwards how the source code can be used within the configurator without even the requirement of utilizing git. That made it easy enough to explain and demonstrate. Also, with the rapid pace of development, it might be fun to check out other initiatives on GH for ELRS. Once you've done it, it's pretty simple. Glad to help...

Great job mate. Love my TX16

[@RCVideoReviews]

Thanks 👍 I'm fond of mine as well.

[@secretAurora9]

you do an amazing job, tanks to bring all this stuff to people, this will make the project skyrocket ;)

[@RCVideoReviews]

Appreciate the comment. Thank you. I'm really happy about this SBUS effort. ELRS doesn't need too many more features to become one of the best cross-platform options available.

@@RCVideoReviews i know thats why i push the sbus thing in the github but im not a coder cant realy help, after month some one take it and build the next step ! have a great one!

Amazing job! Thank you for the instruction video

[@RCVideoReviews]

You are welcome!

I notice you often use a Matek r24d diversity rx in various projects and in large planes. I fly 3d planes with elrs rxs with one antenna in a large city; should I consider upgrading to elrs rxs with 2 antennas?

[@RCVideoReviews]

The best thing I can suggest to do is to get an R24D, and then log your data with the current RX and an R24D and see what the data tells you. I can tell you in my case, my RQLY for LOS is usually never lower than 98% and my TPWR is usually 25mw, with an occasional uptick to 50 or 100mw. Those bumps rarely last more than about a second. I need to do some testing with some of the true diverse RXs out there, but for LOS, these R24Ds latch on to the TX like a pitbull with lockjaw.

I experimented with a RM RP1. I set it for SBUS. On TX16S with RM Ranger I deleted all the function and previous setting from TBS Nano. Using SBUS for ZOHD Kopilot. I cant get it into manual flight mode. It like I have 2 RTL/RTH settings and 1 balance/stabilization mode. Any ideas to get the manual mode to show up?

Channel 5 is binary if you aren't using 16ch/2 or 8ch.

[@frankreinink3239]

Is it still possible to download the Experimental Firmware somewhere? I would like to try it on a helicopter that unfortunately does not support Crossfire.

[@RCVideoReviews]

SBUS has been incorporated into the master branch. Just compile using master and SBUS will be in there.

[@Aviator28]

The github page is not opening. Where can I download this firmware?

[@RCVideoReviews]

It was merged into the release version 3.3.0 You don't need to do anything special to get it anymore.

[@Aviator28]

@@RCVideoReviews Thanks! Happy 😊

@@RCVideoReviewsmy elrs program doesn’t have the invert tx for some reason

[@AvrgAndy]

Just wondering if the SBUS branch also permits telemetry?

[@RCVideoReviews]

Onboard telemetry from the RX will go back to the TX, but that's it. There is no return path from a FC if that's what you're asking.

[@AvrgAndy]

@@RCVideoReviews thanks, yep that’s what I was wondering. Do you reckon they eventually intend to add smartport/f.port for fc downlink telemetry?

[@oazgasme]

Hello!!! Does it work with Matek pwm6?

[@RCVideoReviews]

Matek 2400 RX PWM is listed in the device list. You'd have to compile it and try for yourself. I'm not sure what the situation is with putting a serial protocol on a PWM target is with ELRS. My instincts tell me it won't work as PWM targets are designed to output PWM.
