Is there an api call to check the status of a downlink message? At first the messages were delivered to the device but not anymore so if there is a way to check that would be nice!
There is no option to query the status of a downlink message. Buffering of downlink messages may occur on different places in our solution it is hard to give an clear response to such a request due to the asynchronous nature of the protocols.
Note: after sending an uplink message we will try to downlink all buffered messages.
