I just flashed the 221g6 fw on my 9XRPRO and I can only display rssi 75, tssi 246 and Rx voltage but none of my two sensors; I use both STM and 328 4-1 module.
Is there something to do ?

Thanks Joao, not as easy as OpenTx but it should work...

Is there a way to redirect the RSSI signal to ch.16 ?

I know howto do that with the input menu with OpenTx but don't know with ER9XR

MP

I made it with some pieces of carbon sheet:

I use eepeskye ver.4.15; is that an issue ?

Thanks Joao but that don't work, the BL stays at 1.9; I can only go up to C8; if I flash the E3 I get a snowy screen and I can't stop with the on/off switch.

I need to update the bootloader of my AR9X board in order to flash the last FW which exceed 256K, actual is 1.9; I can't find where this has been discussed.
Thanks

MP

For some reason the flash fail at 95%; If I'm right I have to flash the "T" version ?

On the SD card I have two disks , which one is to be copied the new FW ?

MP

The bootloader of my AR9X board is 1.9; how I can update in order to load the 221 FW ?

MP

I saw an other Flysky Rx give the choice between S-bus & i-bus; maybe an other FW fix that issue ?

Thanks, I will give it a try.

MP

what about the iBus ?, can I connect Sbus servos like FrSky Sbus ?

Since the 4in1 module run the iA6/10b Rx is it possible to add the Flysky telemetry in ersky9x ?

Thanks

The one I got have the connector soldered on the wrong side: copper side...

MP

The best reason to purchase it should be a better HW quality than the PRO, essentially the gimbals; I was told the M9 sticks would fit the QX7.

Hi Joao, Yes, the two bridges are soldered and the module is in JR bay; I can't know the FW: it is the stock one...I wait for the programmer...of course I tried inverted and non inverted in the telemetry menu; in the same way I don't have telemetry in DSM mode where all worked with DJT module and Or...

I assume this the right one:

I have a TH9X/AR9x/Ersky9X-r220 with a multimodule stock FW; I can bind in serial mode with my D8RII but I can't get telemetry either PPM or serial mode which works well with the DJT module.

I'm not sure where is the issue: wrong parameter in ERsky9x-r or multimodule FW ?

The 9XR-PRO pots are crappy !

Thanks JHSA, issue fixed, R9 was guilty, that resistor is a headache : when I tested it with my multimeter I get around 0 ohm, but the voltage at the input of the 5 V regulator was 4 volts... It appears the very little current of the ohmmeter give a false measure, with the power ON, maybe 200-300 mA...

There is something strange: I tested the regulator on the bench with a 5 ohm load and it s OK...after that I removed the mainboard from the case and powered it with my 5 volts power bench: it works...where is the issue since I got just 2 volts at the output of the 5 volts reg. when I received the Tx...

Thank you JHSA

@MikeB

well, I prefer a switching one, I'm afraid a 7805 give too much heat

MP

A friend gave me a failed PRO where the 5 volts regulator has fried; where I could find a replacement part or is it possible to fit a "standard" 7805 ?

Something in the same way for the Jeti stuff:

Hi i3dm,

good job, how did you that ?

I have easily swapped POT3 with a 3 way switch by soldering two 3.3 Kohms between legs.

the issue come often with the pot.; I took the track of one of the Aux. pot.; you can either find a 5K track in one of those toy Tx. gimbal...

On my PRO the issue come from a poor rivettted leg on the carbon track, could not fix it; it is neccessary to find a replacement pot.
I had the idea to take the track of one of the aux. pots. wich give a good way to fix the issue.

I had an X6R with the same issue, back to the vendor.

You can use a S-Bus servo as 4th. channel
