error reading data! / One or more keys are of invalid length. #3

Closed tho-wa closed 6 years ago

tho-wa commented 6 years ago

Used AppEUI and Key from Console. In Serial Output following error is shown: "One or more keys are of invalid length". Regarding to google the key should be only 32 lenght, but the key in TheThings console is longer. Sensor data from SDS011 can also not be read successful, tried different sensors and cables. Any idea how to fix? Thanks Thomas

"One or more keys are of invalid length" solved. EUI was wrong.

Hard to debug withour any more information. What node are you using?

"The error reading data" looks like some connectors are not attached correctly or to a wrong serial port.

Hi Matthias, using TheThings Uno, SDS011 and DHT22. TTN connection is now fine, dht22 reading is ok, but no data from SDS011. Already used other SDS, used other cables, configured other TX/RX pins... SDS seems to have power, red led is blinking and fan is running permanent.

Its now working. Seems to be related to defective wires in the frist attemp.
