Tactic anylink

Move the code from my Arduino test app to a Devo module. Add this id code (it now exists in Python code which bulk-generates sequences from ids and compares them with actual sequences mined from TR624).

Add this to protocol documentation - I made an effort to document this one for a change

May be take a look what happens if you set the number of channels for Anylink transceiver in the range 4-9. The receives tries packets with sizes 4 to 9 bytes, but I've seen only 7 (for 6 channels).

BTW, I can reuse this or similar routine for frequency hopping generation for Hisky and make it production strength - with many simultaneous TX ids active.

Seems to be working:

bitbucket.org/rivig/deviation-3.1-slt

@PhracturedBlue, as my SLT module builds and is fully functional now, do you think it makes sense to include it into next release? I know that 3.1 is supposed to be mainly bugfix, but some re-engineering is going on anyway, so may be it makes sense to include this for wider audience to try as a part of nightly builds. If you think it's worth it, I will prepare a pull request.

OK, I will double test it over the week-end, and then submit.

Tactic SLT module should appear in nightlies, it is made compatible with Anylink module - just replace the protocol from PPM to TacticSLT. That also means that, for example, for Axe 100 Helicopter all channels should be reversed.

Please check it out and report success or problems.

Was that a typeo? ALT?

Could anyone post a link to a known good module to buy? I went through 3 cc2500 modules and this time I only want to install once

Can we get the module from an anylink?

And finally, would this module only be good for SLT, or would it cover any other protocols that deviation already supports?

Sorry for my lack of understanding...

---edit--- This one?

Typo it was. I used XL24L01-D03 bought on eBay. There should not be so many problems with nRF24L01 modules as with CC2500. The latter had problems (probably) because of power amplifier control. Their power amp seems to require separate pin to turn on PA and LNA, and if you need to both receive and transmit, as you do in case of telemetry, you can't just turn them both on. This one does not have this peculiar setup, so any module with PA would do.

Unfortunately, Anylink contains this chip soldered well to the board, and to use it as a Devo module you would need to unsolder ATmega which drives the RF chip.

This RF chip serves the following protocols, as fas as I know - V202, HiSky (fbl100, V922), Tactic SLT, Esky, Crazyflie.

This is the module I ordered:

www.ebay.com/itm/370825162017?ssPageName...id=p3984.m1439.l2649

Had to order a separate antenna lead since I did not have one handy.

I would say this will do as well (cheaper source for the module you mentioned):
www.ebay.com/itm/NRF24L01-PA-LNA-SMA-Ant...2-4G-G9/161143335016

The module I used is closer to this:
www.ebay.com/itm/New-2-4G-6-CH-Wireless-...01-D03-/160763860120

but now it is overpriced.

I got the one I posted for two reasons, one was the very small antenna connector the second was that I had a few other things I wanted from them. Ths way I had a bit more room inside the case with just a cable antenna.

Yeah, I like the one.. ordered a couple of those and some antennas.
Thanks.

Yea, U.FL antenna connector helps for saving space, but I unsolder the SMA connector at all and solder my own one - if you have thin 50 Ohm coax cable it is very easy to make. Just take off 30-31 mm of the outer shell from the cable end, and solder the other end outer shell to ground, inner wire to where antenna is wired and you'll have reasonably good antenna.

Also, it seems Banggood sells the bundle - RF board and antenna for less. www.banggood.com/DEVO-Transmitter-Tuner-...ys-V922-p-89812.html

Saw the one from Banggood, was going to order from them but everything I have ordered from them in the past has taken nearly a whole month to arrive. It is worse than using HobbyKing's cheap shipping option (which I never do simply because it takes so long.)

The good thing about the Banggood item is that it does include the antenna and you get a discount if you buy more of them.

Some stuff from China to North Carolina takes so long that when it arrives I have already forgotten I ordered it in the first place. The one I linked to arrived in New York and was handed over to the USPS in 7 days, now any delay will be on the USPS.

victzh, I've seen you mentioned particular shielded
NRF24L01 module.
I wonder what is the purpose of the two extra pins on the backside of the PCB?

Left side of the pic.
I can't find any pinout for a proper documentation.

Thanks

One is ground, another is not connected at all. They are mainly for physical support of the mounted module, not for signals. You can easily cut it off, which I did.

Thanks a bunch - these pins are to go now

-mike-

what maximum range you can get with this modules? which is better, buying the anylink box(i don't mind the wires) or installing the module to my devo 8s. thank you in advance
