About erskyTx

In erskyTx, flashing SPort devices is done in "maintenance mode", which is entered by powering on holding the two horizontal trims APART. I haven't implemented this on the X20 yet, but if you have the dual boot working you may use ETHOS for this function.
In passing, erskyTx had the feature first, then it was added to openTx!

Hello Mike.
Thank you very much for your work.
My 9xr-pro still in use and no want's to go out😁.

I have a couple of question: 223 firmware from http://www.er9x.com/ will work with r9-m on ExpressLrs, right?
Is it the latest firmware for Turnigy 9xr-pro?
Should work with ELRS, and it is the latest firmware for all radios.

Thanks Mike - the very answer I was looking for. I must have been sleeping during the erskyTX lesson regarding "Maintenance Mode". I use BootLoader mode but I cannot ever recall seeing mention of this mode until I looked here for that very same answer. I put the whole set of pre-Version 2 RX firmwares on my QX7 SD card but have never been able to access them from a menu.
Cheers - Great work
 
Just recently began trying to set up a full house glider for aerotow using a TX16S/ErSky and discovered I had no servo control output from Ch 7.
Tested Ch's 7-10 using copies of a throttle mix from Ch 3. TX display shows expected response from stick movement on Ch's 3 and 7-10, but only Ch 3 servo responded.

Couldn't find anything in the ErSky menus that seemed applicable.
So, assistance to an old phart analog man in activating Ch's 7-10 would be appreciated.
 
When you bind, are you selecting AUTO?
Some of the possible DSM modes only support 7 channels. With AUTO selected, the Rx should "tell" the Tx the correct protocol to use to get 10 channels.
I think you will probably need to use "X 2F".

Mike
 
When I select DSM, "2 1F" appears in the Type row. Bind is always successful, but with only Ch's 1-6 active.
Selected "AUTO" in the Type row, bind was not successful, '2 1F" appeared in Type row. Bind then successful, but only 1-6 active.
Selected "X 2F" (characters were in this order) in the Type row, same result as "AUTO" bind attempt.
Selected "7" (just for the heck of it) in the Type row, same result as "AUTO" attempt.

Repeated the above steps using a Spektrum AR 7000 7Ch receiver with the same results. Only successful bind occurred with "2 1F" in the Type row, then Ch.s 1-6 active, Ch 7 inactive.
 
I need 7 Ch's for this application, but if the limitation is 6 and no more, I be SOL.

Mike, I can post photos of the TX display if you think that would be helpful.
 
Sounds like you have an old DSM2, 10 channel Rx.
I may have a bug where the Tx is not detecting the bind data from the internal module.
After binding, try changing the Type to "2 2F", then the option value to "10Ch". This worked for me on the old, DSM2 Lemon Rx I have.

Mike
 
My 10 ch LemonRX is a DSMX, should have mentioned that earlier. I checked my 2 other 10ch I have on hand, and they are DSMX as well.
LemonRX website states that they "backwards compatible" to DSM2, for what that is worth.

Type to "2 2F" and Option to "10CH" after binding in "2 1F" resulted in all 10 channels inactive. Red "bound" led remained illuminated.
Tried binding in "2 1F" with "10CH" entered and it defaulted back to "0" resulting in Ch's 1-6 active, 7-10 inactive.

On a lark, receiver bound, I tried entering "10" as the Option with Type remaining "2 1F" resulted in all 10 channels active.
Hooray! Success!

Thank you very much for your help, Mike, you are the best.
 
So entering β€œCH” caused a memory roll over event?
Correction: "10CH", not "10" was what I selected from the listing in Options after binding.
I'm not sure what a "memory roll over event" is, but that's what enabled all 10 channels to be active.

It's a binary thing in that changing a binary 8 to a larger number requiers another bit. As it looked to me as you dropped the "CH" that the bite might have been able to register correctly.
Sorry, for going of topic into some irrelevant weeds.

I am wondering if there is a possibility to add an internal ELRS module to a 9xtreme board. I did this some years ago with an Arduino based MPM DIY (CC 2500 only) which can also be flashed by the board. There is an interesting option to flash an ELRS RX to a TX but this would need to be connected to the transmitter via TX and RX. I am missing the Option for Xfire for the internal module.
