Heltec v2: No SPS30 & BME280 data is sent to the TTN Console #7

Closed ThatRed closed 5 days ago

Hello @bertrik, I'm trying to figure out, why no pm & BME data arrives in the console. Only join requests.

As far as I understand, the system consists of the Sensor (Heltec v2 Lora, SPS30 & BME280), someones LoraWAN Gateway, the TTN Console, the sensor-data-bridge and sensor.community/opensensemap.org. So for me it is unclear where the error could be and where to start. The display of the sensor shows what hardware it has detected, the pm measurements and a non working QR-code when the button is pressed. And it wakes up the display. I have included the sensor and console logs.

Can you please give me some hints where to look? Do you need more information?

Thanks in advance.

Turns out it was the antenna and the sensor is to far away from the gateway. The Antenna is probably more tuned to 915Mhz than 868MHz. I tried a different one and now I see the payload in the TTN console and the distance isn't a problem anymore.
