no sensor data shown

[Troubadix]

I flashed the latest_en.bin to brand new nodemcu, entered wifi password and connected SEN55 to nodemcu board:

Pin1 - VIN Pin2 - GND Pin3 - D3 Pin4 - D4 Pin5 - GND Pin6 - GND

and did the config as shown in this file: https://github.com/FijnStofGroep/sensors-software-Leusden/blob/master/bin/picture/ConfigSen5X.JPG

Sadly, no sensor data is shown on "Current data" Site

Whats wrong?

Do not connect PIN 6

Have you add pull up resistors (10k)

We have update (more info and Gerber file PCB) https://github.com/FijnStofGroep/sensors-software-Leusden/tree/master/Doc/PCB_model2

Thanks, I removed Pin 6 but no changes. Read on sensor.community that pullup resistors are not needed? Don't have Pullup resistors on my hand now, need some time to get some and will come back to this later...

With original sensor.community firmware the page shows the sensor but with "-" instead of values when no sensor is connected. This confuses me - why is this not the case with your fw? Had the exact same problem with sensor.community beta a year ago...

Can you check the USB(serial)port with putty Most BME280 has an internal pull up resister Example (BME280 is not connected)

@Troubadix Your question: With original sensor.community firmware the page shows the sensor but with "-" instead of values when no sensor is connected. This confuses me - why is this not the case with your fw?

There are two way of no sensor communication:

1. sensor is connected but rans in a time out (no sensor data will be sent) in this case our fw display "-" values.
2. sensor is NOT connected properly to the NodeMCU board (wiring problem, etc..). there is totally no communication. in this case our fw will not display sensor type at all.
