Serial out for LRS boxes

When an internal radio is active the green LED is on.
Please post a scan of any documentation you receive with the Wolfbox. Haven't been able to find anything that describes exactly the meaning jumper settings. Seems like it controls some built-in hardware that has to be modded into most other modules for serial input and telemetry.
The link you posted is the site of some firmware called UltimateLRS. Banggood says the Wolfbox comes loaded with openlrsng. Which do you plan to use?
Are you planning to use telemetry? The information I found indicates the hardware only supports telemetry if PPM is used for control. Maybe the Wolfbox is different. Banggood just links to the opernlrsng site for Wolfbox documentation, but didn't find anything there specific to Wolfbox. And if you use UltimateLRS an Teensy board must be programmed and installed in the Wolfbox.
So if you flash the nightly SBUS should work fine, with the proper jumper setting and firmware configuration on the Wolfbox. If you want telemetry we'll have to do some experimenting. The opernlrsng configurator software has four telemetry settings: No, Yes, Frsky, and SmartPort. Need to look at the code to see the differences.

Regarding the wolfbox, this is what I currently know (from goggling *Lots* info from past 2 days).
With hardware wolfbox, its an RFM23BP module controlled by an atmega328(arduino bootloader) w/c takes ppm(and sbus?) If its configured to be a Tx... OR spews out PPM(or sbus) along with 1khz(?)pwm->>RC filter for analog rssi.max 3v3. This also depends HOW it is configured. It has a PC app(GUI) for configuring parameters.
I have not installed the ULRS configurator yet.so I dont know what configs are there. Will do that when my UHF arrives.
With the wolfbox also, atmega is i think(?) 3v3 (underpowerd)powered with I think 16MHz xtal. The RFM module is also 3v3 powered. Its marketed as 1watt, but according to measurements, its RF output is only around 400mW.because of 3v3 power. Max it could take safely is 5v to 5v5. Dont believe the datasheet saying a max of 6v.
Wolfbox is a clone(of orangerx , I think?) .
Wolfbox also comes stock flashed with EDIT: NOT openlrsng(!)
flashable with openlrsng or ultimatelrs fw.
What he told me, since im also having a hard time where/how to start, was to Fresh start on "ULRS mini"... And now I finally understood how hardware is setup. Arduino+RF module. He owns the site ive mentioned earlier.
My wolfbox is due to arrive 2 weeks from now. And I have also ordered a few pcs of the RFM modules as well.. For a diy approach. Wish I had done this , before ordering the wolfbox combo.
Actually I have two radios to play with. The T8SGv2+ & flysky i6(fw modded). PPM for i6 and PPM(or possibly SBUS with rssi) for T8SG.
I hope this is clear now. I cant comment any further.no hardware to check atm.
Oh and before I forget, the Orange lrs and perhaps the wolfbox, needs to be flashed with 3v3 FTDI(well it would survive a 5v) but the RF module wont. Its data lines are not 5v tolerant.
Please check ULRS mini. There is reference schematic there and lots of info.

The openlsrng github project page had activity last year so doesn't seem completely dead.

I'm gonna have to design/print myself a module bay to hack into the back of my transmitter. I'd like to switch between r9 and crsf modules.

A bit of wiring and a jumper or switch is needed to easily change between R9M and Crossfire modules if you plan to use CRSF protocol. For CRSF the Devo TX and RX connections need to be shorted together and connected to the CRSF pin (bottom JR pin) on the Crossfire module. For PXX the TX signal goes to the top JR pin (PPM/PXX) and the RX signal is connected to the bottom JR pin (s.port).
Due to the devo8 hardware, when using a serial protocol all voice playback will be turned off.

Indeed I see some jitters in the JRbay, PPM stream viewed from my scope.
Now I need to flash a nightly build. After I see some tutorials how-to

The tbs agent software still leaves much to be desired as far as configurability of the micro tx module. Getting into Lua scripts for more functionality here may be the perfect time to explore some smart audio capabilities.
Gonna jump into PXX next.

I'm testing with the full-size crossfire module - is that what you have? I've tested with firmwares 2.41 and 2.88.
There is no 250mW power setting that I could find for any frequency - did you mean 25mW? If not what are the other configuration settings when you see the 250mW power setting available?

I should also include I am testing with 2.88 tbs version. For whatever reason I can not test any earlier versions as it seems the micro tx module once updated to 2.88 can not downgrade a receiver using either it's button sequence away from the agent or the agent software gui. The module will flash to earlier versions fine but receiver downgrade updates fail and bind is lost. Updating the module back to 2.88 immediately restores bind. So every Rx I have is stuck on 2.88. I've tried on multiple receivers. Maybe the experience is different on a tango or taranis.

The document I have says the power level is indicated by a telemetry value 0-6, corresponding to 0, 10, 25, 100, 500mW, 1W, 2W. Maybe they tacked 250mW on the end which would grab a random value for display. Is it only the power level telemetry that's wrong, or other fields as well?
Made a test build (f156a82) just in case this wild guess is correct. Please give it a try.

Would the log still be helpful? Are you curious to see the actual value being sent back during 250mw operation or are you happy with your solution in the test build? I do not mind recording one when I return.

This capture was taken between the Devo and the TX module. I noticed 12th block from the end was always a 7... but I have not gotten in deep enough in my studies to know what position to look at.

Have a question
Bug?
Just recently updated my T8SG v2plus (to fix the ppm jitter problems) to
t8sg_v2_plus-v5.0.0-cd5f95c
And restored all settings from previous.
When I check max output power, its only 100mW(from the previous 150mW)!
What gives? Was this intentional? Or something I did wrong in restoring some files?
Sorry. Barking on the wrong tree here. Anyways, hows it going with sbus/sumd output?
I have OLRSng/wolfbox here. Ive set it to output sbus instead of PPM. Im not sure though how id set it up to accept sumd/sbus for input. Im on the latest fw 3.9.0.
