All - I am testing my custom device driver with the community edition of ThingPark.

Uplink Decoding and Downlink Decoding is working with no issues through the test tabs on the Driver Code pane.

If I try to simulate Encode Downlink I see the following error message.

{"code":"400 BAD_REQUEST","message":""}

Is there anything I need to do for the Encode Downlink test feature to work? I've checked the Abeeway Asset Tracker device and this feature works OK, but I can't understand what else needs to be done due to this being performed in a simulated context?

Many thanks,

Greg.
