Built a Grove Solar powered Weatherpi station and having an issue with the BMP280 pressure sensor on the Weather board. The behavior I'm seeing is sometimes its present but get an I/O error. Reboot and get not present. On very rare occasions, I get it to work. Anyone run into this issue? I'm thinking bad board.

Intermittent problems like this are rarely electrical and almost always physical. BP

Thanks for the response. All parts are new and hasn't been outside yet. I double the connections and look good. All new grove connectors. I think I found the issue. I changed the power adapter I was using. It seemed to be a little under powered. After powering up with a different adapter, I can see the barometric pressure now. But if I stop the software and restart it, it fails again. I Hoping it will be ok after I setup up the battery and solar power.

This still seems to be a problem.

I first start the GroveWeatherPi software, I can see the BMP280 present. I get and actual value in the output.

(' bmp180Temperature=', 25.25)

After one cycle of the main routine I start seeing

('Unexpected bmp280 error:', <type 'exceptions.IOError'>)

When I restart the software, its not present. I run a TCA9545 test and 0x77 is not there.

Same thing happens when I power off and on the board. When it does work I get a pressure reading but Fails after the first reading. As I'm typing this its currently 30.16 in. Hasn't changed and getting the exception error. Seems like the first time through the routine it takes a measurement then fails after that. If I power off or stop and start the program, I'll get a measurement of 0.00in. I may try to isolate the weather board from the rest of the sensors. Try on a different raspi computer on a test bench. very strange.

I'm also having issues with the OLED display and UV. Tackling one sensor at a time. All else appears to work, weather rack sensors, DS3231 RTC, and HUT21D-F inside hum/temp.

Here is the database entries for the BMP280. You can see that when it did work work, the values are static. Almost as if the variables in the code don't update. This tells me the it worked the first time through the code then failed. The zeros are times it didn't work at startup.

Forgive me if I have asked this before, but do you have an I2C Mux in the system?

If so, disconnect it and hook up the BMP280 directly to the I2C port on the Pi2Grover and re run your tests.

This is really weird.

I am coming down on the side of a bad BMP280. It always comes back after a Power cycle right? Next time it happens, unplug the I2C and plug it in again (BTW, make sure there aren't any other grove cables plugged into the weather board. They also supply 5V.).

Thanks BP. Yeah my last 2 posts were tests done without the mux board. I connected the weather board directly to the pi2Grover. Test results were the same. I do have an HTU21D-f soldered to the board and that works fine. Also the Real time clock which works as well. Shame, it was a new board to. I ordered a new weather board and will test again with that. I'm also leaning towards a bad bmp280. Thanks again.

I tested a new weatherboard i just received and getting same thing. Bmp280 fails after first pass running simpletest.py. I'm wondering now if it isn't the raspberry pi OS, python library, or where the libraries are located in the files stem. I'm using a Raspberry pi 3 A+ board with the latest Buster OS. Python version 2.7 and python 3 installed. The groveWeatherPi software is using python 2.7. I need to understand the PureIO library location. Should it be inside or outside the SDL_Pi_GroveWeatherPi folder?

OK. Please summarize your tests again. I need to see a pattern here.

Current assumptions and questions:

1) We know it is very likely not the BMP280. You have two boards and the behave the same.

2) This is not a systemic board problem. We haven't heard about this from anywhere else.

3) I am wondering if you have a bad Raspberry Pi or SD Card? Can you swap out those too? Give us details on the Pi and SDCard

4) Could this be some kind of a driver problem? Driver version problem? Once we have a simple test defined, I'll duplicate it here.

Thanks for the reply.

I'm using a Pi3 A+ connected to a AC power adapter and not battery. I installed Raspbian Stretch thinking it could be a OS version issue. I've also tried the latest Buster version with same result. I've tried using an old Pi A+ board. with same result. I'm waiting on a pi zero but think I'm going to see the same thing.

Image of my connection to weather board. Very simple for testing.

I ran a simpletest_280.py of the BMP. I get a result the first time I execute but fails the second time. I see the error is related to the I2C.
