Is this it?

Back in 2017, mwm started a tutorial on making up a model .ini file from scratch.
There were many good comments about the tutorial. He had a .pdf file for a while and then it was removed and the only access was on his personal blog. All the references to the .pdf and his blog now point to a URL for sale designation.

Does anyone have a copy of that .pdf so that some of us "newbies" can learn how to program the T8SG?

Here is original thread:
www.deviationtx.com/forum/how-to/3948-tu...-a-model-config-file

The T8SG is very much like my old Royal EVO transmitter. All of the mixer and curve functions are the same.
But what is really different is the "replace" and "trim" functions of T8SG. If anyone knows of a tutorial that explains
how and why you use that functions with virtual mixers, that would be a great aid. Much thanks.

Thank you Hexfet.

There's two versions of ACCST these days. If your XSR is ACCST v1 it should work with the firmware you have. Try the fine freq adjustment to see if you can bind. If the XSR is ACCST v2 then install the firmware from here . This build has another protocol option for FrskyX to set the ACCST version.

It is ACCST. Yes, you are right. It did't bind...

Will this work for you?

Is your receiver with ACCST or ACCESS f/w? I believe it can be bound in ACCST D16 mode only.

I can't get the frysky R-XSR reciver bind with my jumper T8 SG plus V2 transmitter. I am still made a firmware update, i am running t8sg_v5.0.0-abc5dcf, without solvi g the problem. Witch version is the right ones?

I have a Jumper T8SG V2 Plus from just before the V3 launched. When I first received it, I was able to bind to an E011C quadcopter using the Bayang protocol. The firmware is the stock shipped with the TX, t8sg_v2_plus_v5.0.0-e801244. However, the transmitter now seems to start the binding process but not complete. I have the following behavior with the stock toy transmitter the quadcopter comes with and the T8SG V2 Plus.

With E011C drone and stock toy transmitter:

1. Plug in battery
2. Blinks LEDs slowly
3. Turn on TX
4. Blinks rapidly for around 3 seconds, then LEDs go solid.
5. Drone responds to TX.

With E011C drone and Jumper T8SG V2 Plus:

1. Plug in battery
2. Blinks LEDs slowly
3. Turn on TX
4. Blinks rapidly and doesn't stop blinking rapidly.
5. Drone doesn't respond to TX.

I have tried the same T8SG TX with two different E011C drones, so the issue appears to be the Jumper transmitter. I have read that the crystal oscillator on the NRF24L01 transceiver may not have good stability, but I haven't found an example of someone successfully replacing it. Has anyone seen behavior like this before?

dfu is just latest nightly build I got december 2020.
hardware.ini is what I edited.
check voice.ini and every steps as references, probably you already did

Thank You BlackLotus.
I'll check and give info, thanks again.

( setup(), loop() ) or share it on github ?

Dear Goebish,
I attached source code (I converted your code to build on platform IO IDE)

Detail:
1. I am using file Bayang.cpp to modify NRF config fit with tx address, bind channel, payload lengthif possible could you please help me confirm these values via Pulseview data that i attached?
One more thing: I uploaded an esp32 board as TX mode and the rest as RX mode(uncomment #define RX_MODE in file board.h), I received bind packet, but with PROPEL Remote control I was still not sucessful, there is no data come esp32+nrf24 module.

Dear Goebish,
Thank you very much for your attention to my problem.
I will upload the whole source code based on this github: github.com/bikemike/nrf24_multipro/tree/rx_mode soon (about 5 hours latter when I come back home)
I'm using esp32 and nrf24L01+ so I modified that github for esp32.

Any comment.

Dear Goebish,
could you help me take a look at this thread when you have time? www.deviationtx.com/forum/protocol-devel...tx-use-xn297lbw-chip
Thank you.

Dear All,

I have TX with XN297lb RF chip inside.
I want to use this TX to send data to arduino + NRF24L01+
In order to do that, I collected sequence from TX via PulseView tool and found:
- TX address: 0x12, 0xd6, 0x74, 0xbd, 0x71
- RX address: 0x15, 0x59, 0x23, 0xc6, 0x29
- Bind Channel: 0x0B
- Payload: 16
Then I used these value to config for my NRF24L01+ chipBut with this RF setup, I can not get any payload from TX, ( NRF24L01_ReadReg(NRF24L01_07_STATUS) & _BV(NRF24L01_07_RX_DR) ) is alway False
Will be very appriciate if anyone help me check why this problem happened.
I also attached PulseView data that I collected via Saleae Logic tool.

You can go to their website to contact them and find corresponding help

Dear BlackLotus, I tried all the nightly firmwares for devo8. But nothing changed, non of the nightly's have volume control tab in the tx config page.
I thing there is something wrong in .DFU files. May be, if your firmware is working you can share.

I have no Devo 8s here to try it out but i have a look at the Devo 8 emulator nightly version 2021-06-06.
There is a setting for audio volume, the sidebar should be half the way in the middle.
