Measure R9 on the RF module board, inside the radio of course, not inside the RF module :) it should read around zero Ohms, just like a short.. R9 is a current sensor, and normally is the first to blow if you short something. João Trying to get access to the front side of the rf module board to ins...

Is that the resistor immediately to the left of the "h" of hexTronik?
What range should I use on the multimeter, 20k?

I suspect that I have killed my radio when trying to check the voltages on the pins in the module bay. Maybe I inadvertently shorted something...

Now when I switch on, the screen remains blank

What is the best way to determine how bad it may be before I have to scrap it?

9XR Pro :) I am using X series receivers, so would use the S.port connector. I am making an inverter cable to plug in to the BT module which is already configured for 56k. Is the data output through the S.port connector the raw S.port telemetry data from the receiver? Do I need to configure any radi...

Is it possible to connect a HC-05 to either the 3 S.port pins or the 4 serial pins on the rear of an XJT module? I have measured the voltage on both sets of pins to be 4.8v which is ok for my BT module.
If so, is it possible to pipe the Frsky telemetry data out through that connection?

Now at least we have a workaround for the RAM limitation by building a new folder on a PC to replace the original one.
Fortunately, the voice files are relatively stable.

I created a new folder on the PC and copied all the user voice files to it. Then I deleted the user folder on the SD card and copied the entire folder from the PC back to the SD card. Now the files were in the correct order. Then I renamed a file on the SD card on the PC. On viewing the list of voic...

I recently came across some WAV files in an OpenTx script package, which include extra flight modes and other messages I needed, so I copied them to the user folder. I noticed that the stock WAV files were 16000 hz so assumed that the extra files which were 32000 would not work. To my surprise they ...

Since I have been able to flash my receivers, I now would like to flash the external XJT module. I came across a reference to this how-to and would like confirmation that this technique still works as documented before I take the plunge. http://thrustworx.com/frsky-xjt-firmware-flashing-using-turnig...

Fixed by Mike
No doubt the fix will be included in the next release

After powering the RX, 0087 4900 displays immediately (no progress bar) and remains with no movement until I cancel via exit button. Rx is powered from 5v servo rail. Common ground from servo rail to ground pin on radio (grey wire). IMG_20191124_101935_1.jpg IMG_20191124_101526.jpg IMG_20191124_1017...

Followed your instructions and selected Update SPort then applied 5v power to receiver when Finding device msg appears, but I also get
0087 4900 and stops. Green led is solid on receiver, no blue or red showing.
Radio firmware : ersky9x-r222, 06.07.2019
Rx firmware : r-xsr_fcc_190311.frk

So 7-36v then.
In reality it is best to use any type of 3S battery so that the built-in 3S balance connecter can be used.

What is the operating voltage range for the 9XR Pro?
I am currently using a 3S LiFe battery connected to the radio via the balance port lead.

I want to flash the International firmware on to a new R-XSR receiver since it looks like my XJT module may be loaded with the FCC firmware and I cannot bind. The XJT module has a standard 3 pin Smartport connection on the case (smartport, +5v, ground). This is a simple connection which would avoid ...

Hi, I tried to use Turnigy 9XR Pro with latest available R221g1 to update firmware on FrSky R-XSR receiver, following the steps from the PDF on this forum. Because of the 12V Vbat on the module pin, I used external power with GND and Vin connected (Vin was with the switch in-between, as per instruc...

More details are now available in Arduplane v4 docs.
Selecting a flight mode by RCn_OPTION and a switch, overrides the current mode. Switching off reverts to previous mode.
Any free channel can be used.
This is currently only available in Arduplane v4.0.

I increased the timeout to 4.5 and it has solved the problem. Any less and it gets worse.
In Ardupilot there is a way to prioritise telemetry packets, but it is done by group not individual items.

I am having an intermittent problem. FasV is not displayed continuously. Most of the time it displays 0.0v, but every now and then it briefly shows the correct voltage. Other values such as GPS, mAh, etc. show without problems. Voltage on the GCS shows OK at all times I used to have Smartport FLVSS ...

With Ardupilot, it is possible to configure auxiliary functions on any channel using RCx_OPTION. Typically these would be controlling landing gear, camera trigger, etc. But they can also be used to initiate a flight mode such as RTL, Auto, etc. See: http://ardupilot.org/plane/docs/plane-auxiliary-fu...

Turns out that the F405-Wing running Ardupilot cannot handle inverted Smartport telemetry from the X8R. So 2 options: 1) telemetry adapter cable e.g. C&T 2) use a receiver that can provide a non-inverted Smartport signal -- either by design or soldering a wire to a pad or existing joint on the r...

I have installed the latest Arduplane beta 4 on the F405-Wing. Arduplane 4 has new serial parameters to configure UARTs for Frsky telemetry. I have ersky9x-pa4r222 installed on the radio. Previously with a Pixhawk and C&T adapter cable this was working well using SERIAL5_PROTOCOL 10 on Arducopte...

Anyone have this working now? If so, what 9XR Pro and RX firmware versions are you using?

A few more recent observations: I now have Arduplane running on a Matek F405-Wing. I have set the Arduplane rssi params: RSSI_TYPE 1 RSSI_ANA_PIN 15 RSSI_PIN_HIGH 3.3 RSSI_PIN_LOW 0 The rssi signal lead on the X8R receiver is connected to the rssi pin on the FC. The receiver is connected to the FC v...

Hello everyone, I'm a newbie here. I have a problem with telemetry and more precisely with the altitude reading. I've tried different settings but no ideas anymore. My equipment: Turnigy 9xr pro with XJT and on the other side X8R, C&T telemetry cable, Mauh PM, FLVSS (lipo sensor). Here is scree...

I have Frsky X8R paired with the XJT module. The RSSI port on the receiver is connected to the SBUS port on the Pixhawk as per Arducopter docs (RSSI_ANA_PIN = 103). The hi voltage setting in Mission Planner (RSSI_PIN_HI) is set to 3.3v. For example, 1) radio shows a RSSI value of 90, but Mission Pla...

Set them on the small pins and carefully replace the faceplate which will hold them in place.
Look at the horizontal trim buttons, they fit the same.

This works for me (wireless).

That is normal. The range check reduces the power to simulate a long distance.
Move the radio 30 metres away with the model about 1 metre above the ground Check the RSSI value, a safe reading would be 45+.

Forget cables, Go wireless!
