db203can, after flashing OTA firmware 1.14, can no longer access parameters via mission planner DroneCAN viewer

[jkordani]

The units were shipped with 1.13, I connected them to an ODID enabled 4.3.8 ardupilot firmware, connected to the wifi and could see live status. I could connect via Mission Planner and could see the device under the DroneCAN page, inspect the params and save off a copy. After I connected to the website and uploaded 1.14, the webpage still works, I see live data, but when I inspect the parameters in Mission Planner the page is blank. I'm not sure how to edit them anymore. Please advise!

From the vendor

For now the fix is to downgrade the firmware to 1.13 using the webinterface.

Version 1.14 introduced a feature to filter unwanted DroneCAN messages. This is relevant in case there are other CAN devices on the bus that send a lot of packets (CAN ESCs). In such case the ArduRemoteID device cannot handle the amount of CAN traffic. A bug in version 1.14 is that it filters too much packets. Hence, you cannot access the parameters anymore using DroneCAN interface. For now easiest solution is to downgrade until there is a fix.
