[BeauBrewski]

@JulioCesarMatias any chance of getting a RUSHBLADEF7 fix for BMP280 too? 🙏

[JulioCesarMatias]

• @BeauBrewski , please let me know as soon as RUSHBLADEF7 BMP280 is validated.
• the code for both FC are in a single PR
• i'd like to merge before setting up for 0.4.0 release so that i can "freeze" from merging for a bit.

[nerdCopter]

@BeauBrewski , here is 0.3.4 version for public-testers

[JulioCesarMatias]

@BeauBrewski can you tell if it worked for a RUSHBLADEF7?

[BeauBrewski]

@JulioCesarMatias I still haven't heard back from the guy who asked for it.

[BeauBrewski]

Got reply that test file 0.3.4 and new release 0 4.0 did not show the baro for RushBladeF7 and BMP280.

[JulioCesarMatias]

Got reply that test file 0.3.4 and new release 0 4.0 did not show the baro for RushBladeF7 and BMP280.

this is weird.

1 - Is FC looking for the BMP280 automatically on the I2C bus?

2 - Is the SDA and SCL connection correct?

[BeauBrewski]

1 - I'm not sure but can try to ask.
2 - I am assuming so as it works fine with BF.
Here is screen cap of it not working on Emu w/ the 0.3.4 test build:

I've also seen some boards only work the barometer with the battery connected, I don't know if this is the case

[BeauBrewski]

Not showing up with battery connected also.

[JulioCesarMatias]

Not showing up with battery connected also.

How sad, I don't know why it didn't work, I did everything correctly in PR #671

[JulioCesarMatias]

which .hex file did you send the guy to test? Mine or NerdCopter?

[JulioCesarMatias]

I was downloaded and looked at NerdCopter .hex file, and the one he uploaded is smaller than mine. Are you sure you sent mine?

[BeauBrewski]

I had sent nerdcopters .hex. Did the code make it into 0.4.0 for this fw? The tester also had tried 0.4.0 without baro showing.

[nerdCopter]

@JulioCesarMatias , i cherry-picked your mods into older branch, because i did not want the pilot to flash something that the 0.3.6 GUI was not ready to set all features. now that 0.4.0 is out, you can merge master into your branch and send out new .hex.

however, the cherry-pick used your target-definition, so it's still an unsolved problem irregardless.

[JulioCesarMatias]

ok @BeauBrewski and @nerdCopter , so i don't know anymore why it doesn't work.

[BeauBrewski]

Crap. I had an idea/realization. This has been RushBladeF7 HD flight controller that it is being tested on. I don't know if there is any real difference between the RUSHBLADEF7 and RUSHBLADEF7HD, but that might be part of the issue.

I have rush blade f7 hd, if you need me to test something let me know
