Hi, how can I change ports? They are highlighted in grey by default , but they are wrong defined .. PORTC3 and PORTC4 instead of PORTC4 and PORTC5

Hi, rzeszurzeszu.
Thank you for letting us know.
I have fixed the issue and the BMP280 has now been pushed onto the update system.
Can you let us know how you get on, please?

Hello
thank you for update.
FYI : communication works but I get 0 for temp and value 0 for pressure, so something is not correct with this component. This sensor works correctlyIn Flowcode 8.2 .
Additionally this sensor (BMP280) has no humidity element, it has only pressure and temperature.
Humidity is in BME280
Working of sensor is confirmed using Arduino IDE.
Best Regards,

I have a BME280 Module & the BMP280 component working is for me.
I can see the correct Pressure and Temperature.

Hello,
I can confirm that using device BMP280 we got zero (0) as output.
Is there someone else how could check ?
Using BME280 COmponent I get "stange" ASCII signs as output

Can you post your flowchart so I can try it with my UNO and Redboard?

Your flowchart is working for me:
- Pressure & Temp.png (16.35 KiB) Viewed 4316 times
Can you try the attached sniffer, my results for the BME shows:
- Sniffer - BMP280.png (1.95 KiB) Viewed 4316 times
Perhaps the Ardunio is not seeing your device, or the address is incorrect?

Hello,
Port is detected, but the output is still 0 from sensor.
I just tested it using sample code for IDE and it works ... so sensor is OK.
I have found something strange, If i click in gray area on Panel I got information like attached, SDA and SCL are still wrong (D3 and D4)... but in HX711 properties are correct (D4 and D5)
Do you have more idea what could be wrong ?
BR,
mateusz
