I’m using a The Things Uno and a Dragino LoRa Shield with Arduino Uno.
Today, for the first time, and after some weeks using cayenne dashboard on Web and Android sending downlink commands and checking uplink data from devices, it appeared the following message -> “Problem sending command: certificate has expired”.
I’ve checked TTN data right after that and no downlink was even scheduled. However, uplink messages are ok and cayenne dashboard is updating the sensors data with no problem.
I tried to send downlink manually through TTN just to check if there was any problem with the device or the gateway. The downlink message appeared in TTN data and the actuator did what it was supposed to do. So I guess there might me a problem with Cayenne.
Has anyone ever had this issue before? Hope someone can help.
