The adapter light stayed solid blue also, but the radio wasn't communicating with seaclear.

I think he's overly negative. The SH radio uses an older NMEA 0183 protocol, and lacks the easy plug-and-play hookup of NMEA 2000. But if you're trying to interface with older instruments that lack the NMEA 2000 anyway (as I was), it's irrelevant. If I were trying to install a brand new turnkey system with the latest specs, I would get a VHF/DSC/AIS system with NMEA 2000. But that's not my situation, and I suspect it's not yours either.

Without knowing anything about your bluetooth adapter, I can't help much. The blue light might mean that computer is connected, but that may not mean that the adapter is set properly to get NMEA from the radio. What does the configuration software for your bluetooth adapter say? As I said already, I bet it's set to communicate at 9600 by default, and you need to change it to 4800.

I seriously doubt that your radio is malfunctioning or otherwise "busted." It's not the snazzy new NMEA 2000 protocol, but it works fine once it's configured properly, as demonstrated in this other thread.
