I've decided the estimated value, from the CC2500, for the offset did NOT take into account any value you already had set, so the estimated value is a CHANGE.
However, on the Rx I'm testing, the estimated value seems to be biased towards negative values. I've been accumulating 47 estimated values, and if greater than 47 then add 1 to the frequency offset and if less than -47 then subtract 1 from the frequency offset. This causes the offset to slowly go more negative, only stopping when it is clearly below the optimum value.
I did try, a couple of days ago, running the calibration again (triggered by pressing the bind button). The resulting calibration values looked about the same as those at startup.
Looking at my debug output, any one channel has quite a variation in the estimated offset value.

thanks for the perseverance, and to all the github people that have promoted the irx4from a clever idea to an indispensible value added component of the taranis

i'm very happy to no longer need the screwdriver and cp2102 breakout, although it gave me a good excuse to pull out these lovely things

currently on flash special (appropriately) and worth every cent at that price, and even at the advertised "full" price

Bugger, there goes another 20 bucks.
Thanks for the pointer. Pity about our exchange rate.

hey john, you won't regret the purchase

i paid $21.94 aud almost 2 months ago on a promotional special

so far i have really only used the phillips head in the irx4, but between the magnetic "safety" of the handle fit and keeping the screws easily secure, it has been great... it feels serious in a way that all my other mini sets never did

I know what you mean. Those Banggood "use once and we are now a rounded blob" Allen and Star driver sets?

Anyway enough OT - back to normal programming.

About how on Taranis X9D Plus it can be launched? And How? These two app only screen and menu controls are different)

On my radio, system->tools->spectrum.
I'm not sure I follow your other remarks... There is no control at all. The only thing you can do at least with multi is to move the cursor right<-> left to digitally the frequency value at that spot.

This will only be available in 2.3.1

Have an update on what I did wrong. I took a few days break and went back with at it calm and collected and realized I hadn't calibrated the sticks after the numerous bootloader and firmware flashes. Egg on my face I think is the expression there. Rookie mistake right?

Anyway got the sticks recognized and then bam I had control of the surfaces on the ASK. Rx on the K110 has a short still so no go on that one still but yeah was very happy to get it going. Wanna know the next mistake I made after that?

Is it possible to use the iRangeX IRX4 lite Module with the Turnigy protocol?

I am trying to bind an Assault100 microheli with it. No success so far.

As far as I can see the Assault100 microheli is using the Hisky protocol and not Flysky.

Hi, guys. I`m thinking about making this module with only cc2500 module for FrSky`s D16 LBT +D8 protocols.
1, Is it somewhere available >=100mW cc2500 module? On some websites this one
https://www.banggood.com/CC2500-PA-L...r_warehouse=CN
is presented as 100mW. Do You have any experience with it?
2, Will be Arduino Mini Pro enough for such project?
3, Atmega328 at 3.3V is usually operating on 8MHz. Is the schematics with 16MHz crystal OK?
Thanks, Daniel.

1. Yes this is the module which was used to build the DIY module.
2. Yes for sure.
3. You need to take an Arduino pro mini 5v 16mhz that you'll power at 3.3v like indicated on GitHub.

OK, `cause most of cc2500 links are not working. But is 100mW module? Because on commercional 4-in-1 modules the power of cc2500 is around 60mW.

Yes, I read it before, thanks.
