As for the wiring, it's exactly the same as the documentation. The 12v is connected directly to the battery, GND is connected to my main neg bus bar. I have a 12v switch wire connected on the Seatalk One interface next to the yellow SeaTalk data cable.
My SeaTalk instruments - Autohelm - Depth - Wind are all running from a separate switch on my panel.
I can't see any yellow LED blinking
I'm also not getting the SeaTalk link error that I previously had on the autohelm
Ok, thanks for clarifying.
The other user who already reported his test with v1.1 is different from yours but no data either.
To summarize:
Our test
Testing at lab connecting a MFD Raymarine E80 directly to the HAT following the docs instructions. The E80 is getting AIS and GPS data from NMEA 0183 and sending seatalk1 data. The LED is blinking and Signal K is is receiving data without loss.
Dylan test
HAT connection to a seatalk1 bus following the documents. Data is flowing on the bus and the LED is blinking as expected, but no signal in GPIO20 and no data in signal K. There are no errors on setalk1 devices.
Duncan test
HAT connection to a seatalk1 bus following the documents. Data is flowing on the bus but the LED is on and fixed. No data in Signal K. There are no errors on setalk1 devices.
Boatingbaileys test
Waiting for it.
Next moves.
We are waiting from Dylan for some oscilloscope measurements on the input and output of the transistor connected to the GPIO20 to find out why the GPIO is not getting data.
Duncan's case is strange. We could expect the same behavior as Dylan but that LED always on makes me think that it could be a wiring error. Is the brightness intensity high or low? Could you try the wiring option without the power module? Adrian, any idea or extra test or measurement for Duncan?
Hopefully the Boatingbaileys tests are positive because right now it is a mystery why it only works in the lab.
