MAIANA invalid checksums, shifted date ...
#1
Hello,

I bought a MacArthur HAT and MAIANA and I am trying to get it running, but I am still running into issues   Sad

My setup:
HW:
- Raspberry Pi 5, 8GB
- Suptronics - X1004 NVMe dual SSD shield, with 1 SSD (currently; then I will add second one with a clone of fully configured system for redundancy)
- MacArthur HAT (ordered in July; v1.2), with power module
- MAIANA (ordered in July; firmware 4412, HW revision 11.9.1)

SW:
- OpenPlotter 4, after installing available updates: 
   - SignalK 2.11.0
   - Serial 4.1.0
   - MAIANA AIS transponder 4.1.0

Issues:
1. In the MAIANA app, sometimes I am having issues even connecting to the transponder, but in SignalK I can see NMEA messages incoming at the same time.
2. The vast majority (90-100%) of incoming NMEA 0183 messages from MAIANA have invalid checksums => in Data Browser I am seeing updates once per 1-2 minutes – which is not optimal as I would like to forward the GPS position to my VHF (using NMEA0183) which expects the data at least every minute. I had to disable the checksum verification to get frequent updates.
3. Received date (and time) is incorrect, floating and inconsitent across different NMEA message types.
Specifically:
- GLL message - the date is 1-2 days in advance, incorrect time (random hours, minutes always 00)
- RMC message - the date is one month late (08/21), but at least the time is correct
4. In the SignalK log there is some [Object] [Object] error (without any more information) appearing from time-to-time
5. In the SignalK Data Browser: MAIANA.MCUtype = "1" and sometimes correctly "STM.." - and other metadata sometimes seems to be incorrect

Among other things (OpenPlotter reinstall, SignalK reinstall, various troubleshooting efforts, trying different Ethernet cables), I tried enabling the debug mode in Settings and running the MAIANA app from command line `openplotter-maiana` and there was only the Gtk-CRITICAL errors about the GtkScrollbar, which I found here are to be ignored.

Do you have any tips how to get it running properly?

Thank you a lot in advance for any help!
