RE: Connecting NMEA Wind data from NASA Clipper - rmenghe - 2018-05-11 [attachment=281 Wrote:Smartell pid='5052' dateline='1525254924'] Hi Paddy, tomorrow i'm doing the same test: connection of NasaMarine Clipper tactical system to Openplotter. As you can see by the attached file, i'll test two connectivities schema: my preferred one is the option 1 with 2 GPS. RE: Connecting NMEA Wind data from NASA Clipper - Smartell - 2018-05-15 Rmenghe...are you already getting the correct information from your Nasa clipper tactical wind system? (aside from the issue with the GPS connection?) I would like to solve one problem at a time in this thread and getting references from a GPS may be a next step. Any more ideas on how to proceed with connecting Nasa products to openplotter or am I beating a dead horse here? /M Connecting NMEA Wind data from NASA Clipper - Saqqara - 2018-05-16 Here is the simple config I have. Though the label says auto_mpx1 I made manual change of the port. Sent from my Moto G (5) Plus using Tapatalk Some information about my hardware and proof of life. I don't have the Tactical version just nasamarine nmea wind. Sent from my Moto G (5) Plus using Tapatalk Note that I am using inexpensive Prolific PL-2303 USB/serial converters. The other one communicates with a Garmin plotter at the helm.

I will compare my setup with yours when I get back home (vacation in Spain) even if it looks the same. My main question is how you manage to get Openplotter to accept your wind data? Have you connected the cables from the Nasa wind directly to the PL-2303 without having problems with the checksums etc or are you using an arduino converter? Tactical or not, the wind sensor is the same so that should not create any problems. Thanks again for your help! /M Connecting NMEA Wind data from NASA Clipper - Saqqara - 2018-05-19 Your checksums look fine to me. I found an nmea checksum calculator online and checked a few. I just hook it to the USB converters, no Arduino on the boat. The only difficulty I have had is with getting the settings saved by auto config to work, and problems saving things on USB tab. Don't need USB tab, cut out middle man, use the port Linux assigns the USB adapter. I had trouble with my nasamarine unit flooding. Their support was helpful and sent me a new circuit board and a different gasket at a reasonable price. I used silicone and sealed the thing up tight and it has been fine since. I hope they have improved their product. Sent from my Moto G (5) Plus using Tapatalk Nevermind what I said about checksums. I don't know why you get such varied results from different USB adapters. Ftdi are supposed to be better than Prolific. If you had consistent failures I would say take it up with nasamarine. If checksums are wrong it isn't conforming to standard and it should. Their support is said to be better than their quality. Another thing, when my circuit board was wet I had strangeness too, until it corroded out and stopped working.

Does hyperterminal remove any checksums etc? The wind instrument reports the windspeed with one decimal but i don't see that in the messages... /M RE: Connecting NMEA Wind data from NASA Clipper - PaddyB - 2018-06-02 (2018-06-02, 11:22 AM)Smartell Wrote: I connected the mast unit directly to hyperterminal and what i got was this: Just had a look at mine in Putty - got this - (checksum is wrong) Quote:$YXXDR,C,26,C*4D RE: Connecting NMEA Wind data from NASA Clipper - Smartell - 2018-06-03 Thanks for the hint Paddy - Ok, so i tried Putty this time, and got a much better result: $WIMWV,28,R,4.7,N,A*04 $WIMWV,28,R,4.7,N,A*04 $WIMWV,29,R,4.4,N,A*06 $WIMWV,30,R,4.2,N,A*08 $WIMWV,31,R,4.1,N,A*0A $WIMWV,34,R,3.9,N,A*00 $WIMWV,35,R,3.8,N,A*00 $WIMWV,35,R,3.7,N,A*0F $WIMWV,36,R,3.6,N,A*0D $WIMWV,36,R,3.6,N,A*0D $WIMWV,37,R,3.5,N,A*0F $WIMWV,37,R,3.5,N,A*0F $WIMWV,36,R,3.4,N,A*0F $WIMWV,35,R,3.4,N,A*0C $WIMWV,35,R,3.4,N,A*0C $WIMWV,35,R,3.4,N,A*0C $WIMWV,34,R,3.3,N,A*0A $WIMWV,34,R,3.3,N,A*0A $WIMWV,33,R,3.3,N,A*0D $WIMWV,33,R,3.3,N,A*0D $WIMWV,33,R,3.3,N,A*0D $WIMWV,33,R,3.3,N,A*0D $WIMWV,33,R,3.3,N,A*0D $WIMWV,33,R,3.3,N,A*0D $WIMWV,33,R,3.3,N,A*0D $WIMWV,33,R,3.3,N,A*0D $WIMWV,33,R,3.3,N,A*0D $WIMWV,33,R,2.7,N,A*08 $WIMWV,33,R,2.3,N,A*0C $WIMWV,33,R,1.9,N,A*05 $WIMWV,33,R,1.5,N,A*09 $WIMWV,33,R,1.3,N,A*0F $WIMWV,33,R,1.1,N,A*0D Here i see wind data (with decimals) and, as it looks, with the correct checksums - consistently ! (Must be something wonky with Hyperterminal or my setup) So, if this is what the NASA Tactical wind sends when i am using a computer to diagnose the issue... why would this not be acceptable to OpenPlotter? It is also not exactly what i see in the auto-setup process - there the last checksum figure is truncated etc. (see my earlier posts) It is also strange that the auto setup hangs when it enters the auto name creation, just stops/hangs until i remove the RS232 connector by which time it continues to create names etc. /M RE: Connecting NMEA Wind data from NASA Clipper - PaddyB - 2018-06-05 (2018-06-03, 12:10 AM)Smartell Wrote: Thanks for the hint Paddy - Ok, so i tried Putty this time, and got a much better result: Hi , just some more info which might help - I just sent one of your messages to Openplotter over UDP from node-red running in another machine - seems to work fine, openplotter recognizes it and converts to signalk - so whatever is happening your end it seems to be before KPLEX.. RE: Connecting NMEA Wind data from NASA Clipper - Smartell - 2018-06-06 Thanks Paddy ! "Sending one of my messages through NodeRed" ... Cool, more to learn! Problems before Kplex ... so what is there? Hardwarewise i have minimized my rig, disconnected all the additional sensors relays etc. I also use the same setup for the input from the mast sensor as i use with computer/putty. Before Kplex would be in the addition of the mast sensor an that is where i see other problems like the autosetup hanging and the garbled messages from my mast sensor that i see during autosetup I have tried to restart with a clean setup, re-installing raspbian and soforth, "but to no avail" I have more raspberries i can try with but i guess that the latest one, PI 3 B+ is not yet supported so it has to be one of the older ones. (?) Maybe there are some voltage potential/grounding issues messing with the setup? Thanks again for your support Paddy! (No Wind sensor mounted yet!) |
