New "nightly build"

Latest build from master is here (0ec9afb) .

The HonTai protocol has a new format option XKK170 for WlToys K170 heli.
Channels 1-4 are AETR respectively.
Channel 5 is gyro calibration. This is a "momentary" switch. Set value greater than zero (+100) to initiate calibration, then back to less than zero (-100).
Channel 6 is takeoff/landing. Also momentary.
Channel 7 is emergency. Also momentary.

Deviation doesn't implement rate selection in these protocols. The rate is fixed at high and the mixers should be used to tone down the flight controls as needed. The protocol aileron and elevator trim channels are used to extend control throw. Use deviation trims to get level flight with controls at neutral.

Hi,hexfet could you add the DSMX_2F protocol in the multi-protocol to the firmware? Thanks a lot

I see the MPM description of "2F" matches the Deviation implementation of DSM2 and DSMX. If the number of channels is 7 or less the update rate is 11ms. Deviation does not support the "1F" options.

New version is available ( b95aec3 ). Supports new CRSF telemetry values Air Speed, RPM, and Temperature. See CRSF specification for details.

New row added to CRSF telemetry (row 9) on Telemetry Monitor page.
First value is airspeed in km/h.
Second value is RPM. Only the first RPM value is reported even if the telemetry packet contains more than one.
Third value is Temperature in Celsius. Only the first Temperature value is reported even if the telemetry packet contains more than one.

Hexfet,
On T8SGv2 plus, ELRS crashes with this firmware if you try to change packet rate.
When you first turn on transmitter and go to CRSF protocol, there is a countdown until parameters are displayed. When you change the packet rate, sytem hangs at countdown 13 and nothing displays.
With Happymodel ES24TX module, the transmitter now doesnt even recognize the module even with power down and reconnect.

Thanks for the report. Please continue here

New version available ( 36c1c37 ). This fixes the issue reported by rc manic and a display formatting problem.

@hexfet: First of all: Thanks for your Patience and your effort!!!

I am flying a lot of Spektrum umx Planes over the dsm2 protocol. Since the latest Version there was a Change in telemetry: via deviationtx there is Always a voltage of 4,2v comming in. This must BE the RX voltage. The very new umx Planes are sending some more Data. So my question: Would it be possible to get the voltage of the battery? This Would be so great!
Thanks in advance

You're welcome!

I'll take a look but need some more information. Didn't find anything online except some mentions of "...now sends real-time battery voltage..." for newer UMX models. No recent changes to Spektrum telemetry doc or MPM or edgetx. Do you have any more details about the change?

What radio have you tried with?

Deviation already supports the "external input" battery voltage telemetry most common to Spektrum receivers. That's where I'd expect the UMX receivers to send it. This is displayed as Bat on monochrome telemetry test page, and Volt2 on color displays. The 4.2V you mentioned should be shown as RxV or Volt1.

Thanks for your superfast reply.
I was searching the web and found that Screen of the edgetx Software.
So the as3x telemetry is working fine, but we need also the newer DSM smart RX telemetry.
Would be so great to have that!

By the way i am using a Devo8s and a Devo12s.

Thank you

There at 07:26mins you can See that there are 3 telemetry screens on Spektrum TX for the newer (smart) Planes:


Is there a way to See the full log of every Data the RX is sending?

The "nightly build" (4beedb2) is updated with the DSM Smart Battery telemetry changes.

Spektrum Smart Battery telemetry reports cell voltage telemetry. Valid cell voltages are summed together (up to 10 cells) and reported as FLOG telemetry Volt2 (Bat). This mimics the cell summing done in EdgeTX. Cell voltages may be added to the main page and used for alarms (name SmBt.Cel1-10).

The Smart ESC telemetry for RPM and Temp are also displayed in the corresponding FLOG fields so they appear on the telemetry test page.

The "nightly build" (aeb7cd37) is updated with support for SLT protocol format V1_4CH. This protocol is for the new Spektrum SLT2 protocol for the receivers used on RC cars.

Thanks to cirias for the contribution! Tested on Devo10 to pair with SPMXSE2825RX.

PB, thanks for the excellent project! . My Deviation handsets are still my favorites.

The "nightly build" (7df0415) is updated with a CRSF improvement. As PB mentioned, create issues on github for comments.

Hi, hexfet, can you add the loli protocol? It's also one of our commonly used protocols

I had to remove it to make space for other changes. I'll add it back in but will need to remove some other protocol - any suggestions?

Just merged a PR that adds back the removed protocols and adds Propel. Description below. With the impending change of this site to read-only, the nightly build download page is replaced with this download page . I don't have github permissions to host this on the deviationtx github.

The total supported protocols no longer fit in memory for some handsets, so two builds are required to support all protocols. This is not ideal but a compromise solution.

The BUILD_TYPE environment variable is added to control which features are included in a build. The default value of BUILD_TYPE is 0. This produces firmware that supports LOLI and Propel protocols, as well as CRSF configuration menus. The Bluesky, NE260, E016H, and Hubsan protocols are not included.

When BUILD_TYPE=1, the Bluesky, NE260, E016H, and Hubsan protocols are included in the firmware files. The LOLI and Propel protocols are omitted, as well as CRSF configuration pages.

Example build command

When using dmake put the BUILD_TYPE after the command so it is properly passed into the docker container command.

Propel protocol is ported from DIY-MultiProtocol project.
Channel assignments:
CHANNEL1 - Aileron
CHANNEL2 - Elevator
CHANNEL3 - Throttle
CHANNEL4 - Rudder
CHANNEL5 - LEDS
CHANNEL6 - Roll CW
CHANNEL7 - Roll CCW
CHANNEL8 - Fire
CHANNEL9 - Activate weapon system
CHANNEL10 - Calibrate
CHANNEL11 - Altitude hold
CHANNEL12 - Take off
CHANNEL13 - Land
CHANNEL14 - Flight training mode

New updates:
- CRSF protocol option Duplex supports use of rx-as-tx and internal modules that need full duplex.
- 2.25M bitrate added for CRSF. This has the lowest bit error rate and should be preferred for ELRS.
