Sensor data problem

[ghost]

hello again, hope not to disturb. I loaded the last update and I found that it does not recognize the sensor, the probe takes 15 seconds to start, it takes 35 seconds, and it does not throw the sensor data. Could something have happened in the code? I was able to visualize with the weather station logo but with zero values. Sorry for so many questions, and there is very little to work. Thank you

[mikaelnousiainen]

@aledorrego Can you post your new config.h file contents here so we can check what is enabled/disabled? I can try to test the same config locally.

//does not send sensor data neither in cw nor aprs. it pretends not to recognize the sensor. will the change have something to do with using nmea gps output?

Config looks good. I can do some more testing locally with a BMP280. The code did work for me before I committed it to GitHub 🤞

[ghost]

hello. I've been testing builds prior to the weather station update and the sensor is working fine. in fact at this moment I appear in aprs.fi . but with wx firmware it no longer read sensor data. greetings LW7EEA

[ghost]

Hi, friend. could you find if there was any problem in the code? or will I have a local problem with my program? Cheers!!

[mikaelnousiainen]

@aledorrego I tested the current code with your config file and it seems to work for me just fine:

Are you sure that you don't have any other changes in your code, except for the config.h file?

[ghost]

around here we continue testing. The last thing we did was just modify the config.h and compile in Fedora, before we used Ubuntu. The following message appears. Still not getting sensor data

Sorry to hear about the sensor trouble. I'm not able to replicate the issue here -- at least for now.

The latest change with the APRS weather station code does not include any changes to reading the sensor or I²C in general...

Have you verified that you have got the pull-up resistors required by the I²C bus applied to both SCL (clock) and SDA (data) lines? Many BMP280 break-out boards have them, but it's worth checking.

The warning you get during compile is expected and it comes from some test code I have in the repository, not from the actual firmware compilation.

[mikaelnousiainen]

You can try to enable debug logs by following the "Developing / debugging the firmware" instructions in the README file.

That will allow you to get detailed text output about what the firmware does and sends out -- you will need to run the firmware with the (ST-LINK) programmer connected to your computer.

Please let the sonde transmit a couple of APRS packets and paste the full text output here.

[ghost]

Well, I'm going to leave it as I have it working now, with the tower symbol it sends the data well. I tried to install a virtual machine to access with fedora, but my cpu does not support virtual machine. I appreciate all your effort to help me this time, but I have certain technological limitations here. A hug

[leon5265]

Same problem here..

[mikaelnousiainen]

Closing issue with no activity. We have several people that have confirmed BMP280 and BME280 working with the firmware.

Some sensors seem to be picky about the I²C bus speed, so you might want to reduce I²C bus speed to 10000 (= 10 kHz) using the I2C_BUS_CLOCK_SPEED setting in config.h:

RS41ng/src/config.h

Line 30 in 873e281

#define I2C_BUS_CLOCK_SPEED 100000
