Sometimes I got the Error Executing Method iot.agile.Device.Read: null while executing the call: http://device:8080/api/device/bleB0B448BE7D83/Temperature

If I immediately do the create device post it will fail with a timeout.
The solution is to wait a few minutes, create the device again and than it works again.'

Logs of the start of the problem, first lines are ok (got few hundred interations above)

A possible quickfix is to try to connect to the device if the read fails because the object is null.
And in the future it would be great if the connection to the devices will be monitored by a service.

Who should handle reconnection is a nasty topic. If it is offloaded to the service, then states are:
CONNECTED, DISCONNECTED, and CONNECTING (i.e., the service is trying to connect, but it can't for some reason, e.g. the device is out of reach)
For the methods, instead, you typically need:

  • a non-blocking Connect: from now on the service tries to connect ... and reconnect
  • a non-blocking Disconnect: disconnect and do not try to connect in the future
    However, if these are non-blocking, you also would like to receive status change notifications, right?
    So we either need blocking versions as well, or a way to have device status notifications.
    Opinions?
