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.
