I am trying to establish a bidirectional LORAWAN link between a ST Discovery B-L072Z-LRWAN1 card and a cayenne mydevice application through a TTN gateway.
I used as a basis of work:
I added the cayenne library which allows to build the payload in cayenne format.
The rising link works perfectly, I get the graphics information on cayenne.mydevices.com
On the other hand, the descending information coming from the site cayenne.mydevices.com reach the gateway, are transmitted to the node B-L072Z-LRWAN1 which indicates well the reception of a message but the software indicates a reception error in the terminal:
The code -1001 seems to indicate a lack of data received, but this indicates the transmission.
Has anyone encountered this problem?
Can you help me ?
