Update common-storm32-gimbal.rst #885
Conversation
Added warning about RF interference from Storm32 boards.

@olliw42 Do you want to comment on this? |

@OXINARF I can NOT confirm this. I've tested several boards with a RF Explorer and haven't seen any noticeable interference results on the common frequency ranges (433M, 868M, 900M, 1.2G, 2.4G, 5.8G). We have several of these units in industrial environments in production all around the world, so it is important to verify these issues. |

hey, thx oxinarf, and thx luis |

It's quite clear from the discussion on RCG that it has been an issue for
several people.
I added the note as warning (and Ollie even thanked me for it on RCG).

My testing does not confirm your statement. I might have misused the testing equipment (RF-Explorer), so please confirm with some measuring equipment. |

Here's Ollie himself confirming it:

Here's another user testing it on the 433mhz
https://www.rcgroups.com/forums/showpost.php?p=34132760&postcount=579
I have no equpment for testing it against the 915mhz band, but both myself
and another user were unable to reliably connect with the 915mhz telemetry
radios with the gimbal running.
Now, given that safety is always a overriding issue, don't you think it
would be prudent to put up a warning on a product that the developer
himself has repeatedly stated is a hobby project and should not be expected
to perform to professional standards?
Further, if Ollie wants to add solutions, he can add them himself.

Had a STorM32 over here and redid a testing (only one unit so not very relevant) and the difference with the RF Explorer antenna right on top of a STorM32 is very small with or without power (noise floor). Biggest relevant difference is around the 350MHz
a range change shows another peak on around 700MHz
Noise floor increase is negligible all around up to 1150MHz I would start to check if any cabling might be radiating. Note: Just checked that this specific board is from GLB origin, still with the supplied firmware and the original IMU attached |
|
I just checked and there's a notice on the STorM32 wiki about an issue with RF noise, and also a solution to the problem is pointed, but only on a very specific board variant. http://www.olliw.eu/storm32bgc-wiki/STorM32_Boards If you don't mind rephrasing your comment and pointing to the solution it would be beneficial to other users. edit: for completeness, the board tested now is this

Hello all, I have both boards. Someone could confirm if I can use the GLB STorM32 v1.31 without issue into 433mhz band? Thank you |
|
Just in case your STorM32 has a RF noise issue follow these recommendations |

Merged, thanks! |
