Devo 12s 3in1 / 4in1 RF module neat installation.

Did a open filed range test with 3-in-1 module+Devo10 today,

CC2500:
DEVO 8S + CC2500 : Frsky D4R-II @ 3mw >>170M (Environmental limitation) RSSI min. 42db
DEVO10 + 3-in-1 : Frsky D4R-II @ 3mw ~150M~160M RSSI min. 23db

A7105:
DEVO8S doesn't install A7105. Do not test.
DEVO10 + 3-in-1 : Flysky FS-GR3E(RC car receiver) @3mw ~120M

nRF24L01:
DEVO 8S + CC2500 : V2x2 JJ1000 @ 3mw ~140M
DEVO10 + 3-in-1 : V2x2 JJ1000 @ 3mw ~130M

I don't know why it is but i have had this issue before. Full format of drive copy fresh, exit USB nice and bam it wiorked direct on B3.
Maybe devo does no take that you edit and save direct from notepad++, anyway no clue as othe modules worked. But I had same before in the pas.

just found this thread yesterday. placed an order for 3 in 1 immediately.
since i have four 7e on hand, i would set up one on devo and use it as a yard stick in testing out the range check against other protocols.

Welcome back!
I think you can get it soon, would you please help to check control range and power consumption of 3-in1 ?
Thanks.

I did a test,I connect 3-in-1 LNAEN pin to VCC,and it works perfect! I made a indoor test also @3mw , D4R-II frsky condition get almost same result as DEVO8S+CC2500 , control range and telemetry range improved. I don't know why that Skyartec Wasp Nano CP heli receiver get same control range as DEVO8S+CC2500,why LNAEN can do that ??

Is there any A7105 & nRF24L01 receivers have telemetry function? want to do some more telemetry test.

EDIT : New Flysky protocol with telemetry function seems under developing HERE .

The only currently supported A7105 protocol with telemetry is Hubsan, and it only supports voltage. The Estes Proto X is a nice inexpensive nano-quad that provides voltage output. Not really useful given it's size and LED LVC warning, but it's there.

The YD717 and Cflie protocols (NRF24L01) both support telemetry, but it's disabled in the build for some reason. It appears both provide frameloss data, and maybe (the comments imply it, but I can't find where it's set) voltage data. I have no idea which - if any - of the supported craft actually provide it. However, if you get one and want a custom build, let me know.

It's disabled in yd717 because it doesn't provide much benefit in a quad that small and it's only pseudo-telemetry anyway. The aircraft doesn't send any info - the data comes from the tx count of missed packet acknowledgements. No help for checking the LNA.

You might see better range on the quad without laggy behavior due to missed acks, but that would be pretty subjective.

The frame loss count from the Tx is actually useful - if it's accurate. FrSky provides something similar - the Tx-side RSSI - in their telemetry data. It comes out of a CC2500 register, and hexfet & I have talked about adding it to the exiting FrSky telemetry.

If we're actually going to do a more complete Hubsan telemetry, i think we need a better telemetry test page. Right now, the code actually includes three different versions of the page, some of them multiple pages long. But that really belongs on a new thread.

How about the PA & LNA switching? On a CC2500 module it is done by using the GDO pins.
Or does it mean, on this 3in1 it is done the same way but internally and with a given option to tie this to a certain function?

I have no idea about PA/LNA switching, and I can't find GDO pin on 3in1 module, it supposed to be done in internal MCU I think.

Hopefully, they wired the pins up properly on the PCB. The question is, did they wrote it for 4.0.1 or later?

Just discovered this thread .... Amazing ....

To resume :

Possibility to install the 3-in-1 module now in 7E,10, 8S ?
No LNA in the 3-in-1 so shorter range ?

Can the 4-in-1 be installed in a 7E ?

Did a range test again, after I connected LNAEN to VCC, all same power 3mw setting.
CC2500:
DEVO 8S + CC2500 : Frsky D4R-II >200M (Environmental limitation) RSSI min. 45db
DEVO10 + 3-in-1 : Frsky D4R-II >200M (Environmental limitation) RSSI min. 43db
DEVO 8S + CC2500 : Skyartec AP301 receiver >200M (Environmental limitation)
DEVO10 + 3-in-1 : Skyartec AP301 receiver 150M~170M
It seems independent CC2500 module still better than 3in1.

A7105:
DEVO8S doesn't install A7105. Do not test.
DEVO10 + 3-in-1 : Flysky FS-GR3E(RC car receiver) 150M OK,150M~200M unstable, at 200M not totally lost signal,just unstable.

nRF24L01: not tested today

Reference:
DEVO 8S + RX1002 : <180M OK, 180M~200M unstable
DEVO 10 + RX1002 : <180M OK, 180M~200M unstable

I just want to say ,frsky is amazing, and it's pretty tired to do range test.

I will try to contact with seller and find the answer.

If you have good soldering skill, Yes, 3-in-1 could be installed on 7E/10/8S.

It now has LNA.

Can the 4-in-1 be installed in a 7E ?

I don't know at this moment, can someone help to deal with PE1/PE2 connection problem?
or just wait for daughter board.

Do you mean there will be some revision of these two boards ?

The TaoBao seller told me he will try to make daughter board, but there is no schedule info,
and he did not agree to provide schematic of these two modules.

.

Just one note.
The A7105-500 does at 3mW more than 200m with ease.

I know this, because the year before last I nearly lost one of my V911 in strong wind
At estimated 230m I switched the transmitter off and let the heli drop . She was found at 265 m ( google maps measurement)
