The range is only about 4 to 5 feet. I did not change anything in hardware and software configuration.
Does this mean the 4-in-1 module is gone, or can it also be another hardware or software problem.
I already checked connecting a different antenna direct to the 4-in-1 module, this has no effect.

I was thinking that too, but antenne was never off with the transmitter on....vlad_vy wrote: Most likely you damage RF power amplifier at 4in1 module. It can be damaged if transmitter powered on without connected antenna.

I have indeed a white Devo10, is there an easy way to check that connector?vlad_vy wrote: If you have white Devo 10 with detachable antenna, I think it has UFL connector at small PCB inside antenna holder. That UFL connector can lost contact with antenna, I had such case with Devo 8s.
Otherwise I might replace the 4-in-1 and immediately have the same problem...

Do you mean the connector on the wire that is going to the antenna? If yes, both ground and center are zero at both ends, meaning they should be OK.vlad_vy wrote: You can check resistance between RF module UFL connector and output Antenna connector, for both ground and both center contarts.
Is it also possible to check resistance with UFL connector connected to the 4-in-1 board? For ground that should be no problem because I think the shielding on the board is grounded, but is there a connector point on the 4-in-1 that is directly connected to the antenna signal?

I'm afraid I'm not expert enough to do that.wasp09 wrote: Replace RF power amplifier.
Is there a way to check that is the problem or can there be no other reason to cause these problems.
I still don't understand what can have happened, since al antenna connections seem to be OK now.

I replaced the 4-in-1 module completely and now my Devo 10 is working OK again.llinde wrote: What to do next, replace 4-in-1 module?
I'm not happy because I don't know what caused this, all measurements on the antenna were OK.
Is there something I can examine or repair on the defect module?

Picture of F7 Board with NRF24L01 (U.FL Antenna) on right.
Attachment not found
Can anyone confirm what the pins get connected to.
From what I've read it connects to A13, A14 and A15 for the Multi module.
I only need one of these but don't know where it is on the board.
NRF24L01 (U.FL Antenna)
Attachment not found
4 in 1 Module (for pin identification)
Attachment not found
On the Module I can see i need to connect,
From NRF24L01 to existing RF Module.
3.3V and CE to VN
Mosi to Mosi
Miso to Miso
Gnd to Gnd
Sck to Sck
I'm assuming CSN goes to either A13, A14 or A15 (dont know where they are).
I'm unsure where to connect IRQ from the NRF24L01
Any and all help is apreciated.
