Hello, I had this happen when I was bench testing the PDM, but wrote it off to just me being new to the platform. Today I finished wiring in my PDM15 to my vehicle and only once was I able to retrieve the config. Now I can neither send nor recieve a config, I just get the circle icon on the send or receive button. SOmetimes the Rx and Tx show activity when retrieving, but as soon as I hit send it stops. Any ideas?
