Hi,
There are 3 useful LEDs on the back of the board for GPS, AIS RX and AIS TX ... unfortunately, without a system of mirrrors, these are of no use once the unit is installed and are not copied to GPIO pins.
I can detect whether the Maiana has GPS position from the NMEA messages, so that part is not a problem ... but I would REALLY like to be able to detect the TX status ... to see in SignalK if it has transmit enabled, maybe the time since last transmission would be nice ... is there anything I can do to assist with this?
The reason I ask is last year it worked great, but I had it just connected in the cabin with a short length of RJ45 and an SMA->BNC to feed the spare antenna. This year, I made an aerial and installed it properly on the back of the boat. The antenna match is very good, but it only seems to want to transmit occasionally. When it does, I get great range (I have been received by stations 20 miles away) but most of the time, despite a good GPS position, it seems not to transmit.
I have a version 10.0 Maiana board ... it would be good to be able to tell if it thinks it should be transmitting or not!
