Hello, alright? I need some very urgent help now, I hope you can help me again. I have the following configuration, Bar30 sensor, connected to the I2C port of the Navigator that is with Ardupilot, and RaspiberryPI4 with BlueOS. The problem is the following, everything works perfectly, only the p…

Hey, i did that, didn´t help. I used 3 Ferrite cores between the sensors ant the Navigator Board. That did the trick.

Hi @Igor , I suspect this is a parameter issue. Can you make sure you’re using QGC 4.2.3 open the Parameters page save your parameters to file (as a backup) reset default parameters (which will hopefully solve your issue)

Hi @EliotBR , I was keeping up with @Igor today, and we noted the mavlink message SCALED_PRESSURE2 wasn’t showing up. He tried both reinstall QGC and reflash BlueOs with no success. He tested two different BAR30 in 3 different Navigators, and none of them have worked. Tomorrow morning we’ll try to…

Most likely the issue is one of the following: [image] Depth Sensor Not Connected message Can you confirm the following parameters: Parameter Value BARO_EXT_BUS 6 BARO_PRIMARY 2ndBaro (1) that the sensor is plugged in to one of the I²C 6 ports, rather than one of the ADC ports in …

Unfortunately it didn’t work. The BARO_EXT_BUS is showing as Unknown:6 [image]

[image] Vagner Martini: The BARO_EXT_BUS is showing as Unknown:6 That should be fine. Can you please confirm that You’re using QGC 4.2.3 The sensor is plugged in to an I2C 6 port [image] The MS5611 (Bar30) sensor is detected as a barometer on the Summary page [Screen Shot 2022-08-19 at 1…

Hi, This is how the sensor is plugged in (tried both): [image] And the sensor is not being detected: [image] And I set the parameters as specified. We are going to a field job this weekend, and we’ll use the old setup with Pixhawk + old Bar30 version I’ll try to test the sensors myself as so…

Hi @EliotBR , I tried to run the Code Guide to Using the Bar30 with a Raspberry Pi directly on RPI4, but when i initialize the sensor I got: >>> sensor.init() PROM read error, CRC failed! False

I expect that’s either from noisy communications (you may wish to try again, preferably making sure the cable is away from other electronics), or from a faulty/broken sensor. If that doesn’t help I’d recommend emailing support, in case they have more ideas, or they determine it’s best to replace the…

Hi Elliot, It’s been a long time since this thread was opened, but only now we could put together all the pieces in the workbench to test them. Unfortunately, one of the pressure sensors is not working at all, no matter the tests we do.

Hi @VMartini , If a product you’ve bought from us is faulty / isn’t working then you’ll need to contact support@bluerobotics.com , to let them know what’s going on feel free to link to this post for some context how the product has been stored and handled any tests you’ve done, and the order num…
