Issues with Archer Plus GR6 - servos bind at an extreme

[phamiltonsmith]

Hi
I recently purchased an Archer Plus GR Receiver

I was able to register/bind the Rx in both ACCST and ACCESS. Telemetry was received correctly: Rx voltage, Vario readings, Altitude, etc. I know telemetry works ok since ALT reading vary as the Rx is moved up/down.

The problem: when i connect any servo to any set of pins, the servo is automatically sent to an extreme. So much so, the servo binds at the extreme.

I am running latest V of FW/bootloader (2.3.15) and RF V2.1.10 in Tx. I am also running latest V of FW in Rx (V1010)

Ideas, thoughts?

Make sure you don't have anything odd setup in the receiver options. Avoid "race mode" or any of the bus outputs for the channels. Can't think of anything else off the top of my head.

Tks for the reply!

By "anything odd in th Rx options" what do you mean? I downloaded the FW from the FRSKY site and flashed that... No "options" can be set... Am I missing something?

If you have a transmitter running Ethos, then you will have some options that be be set from the RF page (near the bind features).

Not sure what transmitter you have?

hmm no, I am running Taranis...

The more I read and investigate, the closer I get to abandoning FRSKY and migrating to the other brands...

If you are using a Taranis, but have ACCESS available, then I'm guessing you have a 2019 version of the Tx.
There is a problem with the Rx options in openTx when using some Archer plus receivers. This is fixed by using the version of openTx I've posted here: https://openrcforums.com/forum/viewtopic.php?t=14126

Thanks Mike - Does his issue sound right though? Can bind but no PWM?

Doing a quick test here..

@phamiltonsmith I had problems using an Archer R8 Plus with my QX7-ACCESS, though not the same as yours. I was able to bind without problems, and servo operation was normal, but a number of Rx features (OTA, options) were missing. The problem was solved by using a customized version of OTX 2.3.15 provided by @MikeB. If your radio is listed among the ones in the link he provides above, that is your solution. It will still require some fiddling with Companion and updating Bootloader and the radio firmware. Try that and let us know if it worked.

In case it's of any use, here is a link to the other thread:

Archer Plus compatibility with ACCESS & OTX radios?

What is the current status of Archer Plus Rx's compatibility with ACCESS radios running OTX? I purchased an Archer Plus R8 about a month ago, and today tried to install it in a new plane, but am having problems. Registration and binding with my QX7-ACCESS went OK, but the radio info page...

When utilising certain Archer Plus receivers, there is an issue with the Rx choices in openTx.

There is an Archer plus GR6 and an Archer Plus GR6FB.
Please check that you bought the correct version.
While the firmware is the same file I think the GR6FB will be set to to FB instead of PWM output.
