Flysky AFHDS 2A, protocol as used i10, i6, iT4,

G'day all!

Any more news on the telemetry for AFHDS 2A?

I have been flying my micro quad with the FS-A8S and Devo 7e for the last few weeks and love it! Connection seems to be rock solid! This receiver does not seem to support telemetry.

I have also got my X6B RX set up with a control board. I haven't finished building the quad yet but can verify that the transmitter binds and everything looks good in Betaflight.

Cheers!

Hi, mazi.
How did you get the iA6B receiver to bind using Devo 10. I have iA6C. Not sure what protocol to choose for binding. Suggestion is appreciated.

I have been using iA6B receiver with my Devo 10 and love it. Does X6B receiver work with Devo before I order one? Thanks.

Hi, goebish.
has to have A7105 module installed in your Devo 10 to make use of this AFHDS2A protocol?

Hello everyone!

First of all i want to congratulate goebish for his great work reverse engineering AFHDS 2A protocol,
and everybody else that is involved. I have project in mind and i need your advice if it is doable.

I want to add a Bluetooth SOC in my FlySky-i6, listen to A7105 SDIO port for RX packets,
and capture AFHDS 2A telemetry data sent by Cleanflight to upgraded FS-iA6B's sense ibus.
I am using those projects as a base:
www.insidegadgets.com/2015/09/03/adding-...-tgy-i6-transmitter/
github.com/benb0jangles/FlySky-i6-Mod-/t...20Mod%20i6%20Updater
www.rcgroups.com/forums/showthread.php?2...e-1-6-with-a-ST-Link

I think benb0jangles' latest firmware for FS-i6 supports extended telemetry.
Searching around deviation src, i was only able to find these sensor ID's in flysky_afhds2a_a7105.c :
Are there any other known sensor ID's available at the moment? And most important, is this project doable?
I know my question is out of the scope of this topic, but i was not able to find any other data about
AFHDS 2A and A7105 on the internet. Thank you for your time and keep up the good work. Cheers!

Yes, see here:

Iirc I got the other one via Betaflight/Cleanflight.

Hi all,

Can anyone please tell me how to update FS-IA6 RX firmware (Not B )
My RS seems to have old firmware and therfore sending wrong RSSI signal.

Regards,

Jasper

Sorry if this is a stupid question - but is A7105 module something I can buy and fit. i am not sure I can lick a stamp and get positive results though!
I have a Devo 10 - which I never use and nobody want to buy and I use an FSi6S - so if I can get my Devo 10 to see the FS rx... it may get an extended life...

EDIT: afterthought - its well know that getting the FSiA6 RX to bind with other TX - RCGroups has a lot of posts about this issue with the FS and TGY versions.

Does this apply with the Devo?

Hey guys just to report something weird, but I expect has more to do with the RX firmware than deviation.
Using FS-X6B, receiver.

When connecting ibus to betaflight Airbot F4, I get ranges 1000-0-2000, all fine
But when setting same receiver to Sbus also betaflight Airbot F4 the range is bit off. 1030 - 15 - 2000
Anyone seen that?

Just adjust endpoint accordingly. Whenever you change Rx / Protocol you must adjust endpoints/center.
We all do this, while looking at Betaflight Configurator. But the over-the-air protocol is the same, and and digital no matter what output comes from the Rx.

Is this all channels ro only Throttle ? I have actually seen throttle seems be have a higher default minimum across different transmitters.

I can take your explanation for PWM and PPM signals.
For digtal signal SBUS and IBUS, I would assume the digital value are sent to be same. I use same RX same TX, same flightcontrol just change ibus to sbus settings.

Anyway indeed you could get away with it and adjust endpoints, but this is kind of harsh solution.
I reporting it here just to point out that maybe the Flysky RX, SBUS implementation not fully correct, maybe someone can confirm.

(BTW the RX just received from BG this week, not flashed any firmware, stock it send telemetry, not checked if there is new RX firmware and what to load)

Something else on this protocol, to set Failsave, all movies on the web show, it must be done from the Tx, it is pretty dangerous to fly without. Currently when signal stops it keeps sending the last received values.

Anyone knows ? How can we set the failsave ?

Thanks missed completely about that, will give it a try!

I have seen in different places that the X6B has firmware issues in earlier models.
Failsafe only works on PWM, not PPM/iBus. Does anybody have the new updated firmware ? Or how can I read it out ? Did upgrade 2 old iA6B from 6 to 8 channel PPM output using Goebbish instructions.

And it actually looks like the X6B can be used for full 2-way telemetry as well (From iNav/CleanFlight/Betaflight), somebody saw the sensor requests on one of the iBus pins/pads. Current status of that code is, that it can use a singe serial port if you add a resistor and a diode.

Guys!
Someone can help me on x6b bind? I cant do this. Im turning on receiver while őushing bind button, its flash rapidly after that i push bind on tx but does not bind
Help me out pls!

Goebbish from your iA6B firmware update research, do you think all receivers share same firmware ? Can I flash iA6B fw on x6b?
